Large-capacity lithium storage battery industry and new energy synchronized planning

The increasing scarcity of traditional energy and the environment is getting worse, greatly Laptop Battery promoted the development of new energy, new energy power generation scale rising fast. However, wind power, solar power inherent in their own random, intermittent in nature determine its large-scale development are bound to the safe operation of power peak-shaving and the system has brought a significant impact, there must be an advanced energy storage technology as their support.

Abroad, the study shows that if the total installed capacity of wind power installed capacity accounted for 10% of the proportion of less than rely on traditional power technologies, and increase the water and electricity, gas-fired units and other means, the basic grid can guarantee security; However,Digital Camera Battery if the proportion of 20% or even higher power grid's peak load capacity and safe operation will face enormous challenges. Energy storage technology to a large extent solved the randomness of new energy power generation, volatility problem, you can achieve smooth output of sony DSC-T7 battery new energy power generation, can effectively regulate the new energy power generation power grid caused by voltage, frequency and phase changes, so that a large-scale wind power and solar power convenient and reliable way into the conventional power grid.

China's imminent large-scale development of new energy on the storage industry has a more pressing practical needs. 2020, wind power and solar power generation equipment to break 170 million kilowatts, accounting for the proportion of total installed generation capacity will exceed 15%. However, as China's power system, a high proportion of coal in some areas are primarily peaking capacity of poor heating units, nuclear power has developed rapidly but they can not participate in peak shaving, water, electricity, gas and power generation peak-shaving power of superior performance percentage is too low, leading to the existing power system is weak acceptance of new energy sources.

Energy resources with China's seat away from sony NP-FE1 battery the load more, the forced implementation of wind power, photovoltaic focus on developing large-scale, long-distance transmission, which further increased the power grid operation and control risk. With the new domestic scale of the rapid expansion of power generation, power grids and new energy sources will be more striking, more urgent the demand for energy storage.

Large-capacity storage but also to improve energy efficiency, in order to save the country substantial investment. In response to City peak load power systems add significant investment every year for the power grid and power back-up capacity-building, but the utilization rate is very low. The Case of Shanghai, 2004 to 2006, in order to solve the city's annual increase of 183.25 hours of peak load, only the grid side of the investment each year by more than 200 billion yuan, for which purpose the formation of transmission and distribution capacity of the average annual utilization rate is not to 2%.

But also in response to peak load, shift to high-capacity storage technology, not only investment will be greatly reduced, and because the storage facility sony NP-F10 battery occupies a small, non-emissions, the festival, the energy-saving, emission reduction measures in effect in other peaking can not be compared.

The world's large-capacity storage technology, a diversified development pattern was

The world's main energy storage technology, physical storage, chemical storage and electromagnetic energy storage (such as superconducting magnetic energy storage, etc.) three categories.

Current technology the most improved chemical energy storage, in which sodium sulfur, vanadium flow and lithium-ion battery technology in the security, energy conversion efficiency and economy and achieved a major breakthrough in terms of industrial application matures. sony NP-FM51 battery Sodium sulfur battery charging efficiency are able to achieve 80% of the energy density of lead-acid batteries three times longer cycle life. Japan has a leading position in this technology.

In 2004 Japan's Hitachi automated factory-installed at the time the world's largest sodium-sulfur battery system, when the capacity is 9.6 MW / 57.6 megawatt-hour. Vanadium redox flow battery based material is vanadium, the battery with energy efficiency, electrical storage capacity, to 100% depth of discharge, long life, etc., has entered the commercial phase. Lithium-ion battery is a lithium-based materials, has begun in electric bicycles, electric vehicles and other field applications. In recent years, due to Lithium iron phosphate, lithium iron phosphate nanotechnology and other new materials development and application of greatly improved the safety of lithium-ion battery performance and cycle life, high-capacity lithium battery energy storage power plant is gradually emerging.

Chinese enterprises have mastered the key to large-scale energy storage technologies with independent intellectual property rights. sony NP-FM50 battery Such as Beijing Pu can VRBPOWER Canadian companies through acquisitions, has in the world, has more than 50% of the vanadium battery core of invention patents, including 15 core patents in 24 countries and regions in the world applied.

The key materials in the battery, domestic enterprises have also shown a strong ability to innovate, often breaking the monopoly of foreign enterprises of products and patents blockade. Beijing Golden able to create their own fuel-cell companies use the resin dissolved in the casting method, has been mass-produced perfluorinated ion-exchange membrane, breaking the U.S. market for DuPont's long-standing monopoly.

Shenzhen Star source material through the past five years of independent research and development has now mastered the production of lithium-ion battery membrane key material used in the core technology and production processes, and has been the use of low-cost domestic product, the unique advantage of the rapid breaking of the Japanese, the United States and other country's few companies a monopoly on diaphragm material. The Shenzhen side Denamy technology companies use nanotechnology, sony NP-FR1 battery has successfully developed nano-lithium iron phosphate cathode material, the main technical indicators of the world's leading.

Energy storage technology is toward large-capacity, high conversion rate and the direction of application of low-cost development, which has independent intellectual property rights and the simultaneous advantages of low-cost production in China, providing a rare opportunity to lead. If the policy in place, China's fast-growing storage industry can have a major impact in the global emerging strategic industries, will greatly promote the domestic large-scale development of new energy sources.

China's large-capacity storage industry still faces many institutional and policy constraints

Lack of storage planning. In recent years the rapid development of new domestic energy sources, exposing the preparations of the many deficiencies. On the one hand the development of network planning and power supply out of touch, power grids, could not keep up with the timely development of new sources of energy; the other hand, technological progress is energy storage, as well as energy storage in the new energy development, the special role of the lack of knowledge, energy storage planning and grid, disconnect the power plan. "Two out of touch," a direct sony NP-F550 battery result of the contradictions is that the new energy and power gradual deterioration.

Pricing policies for energy storage power station and return on investment mechanisms missing. Now grid side, power generation side, the user in increasing awareness of the unique role of energy storage technologies, energy storage industry also attracted many investors. However, due to two aspects of price policy is not in place, energy storage industry is a lack of investment return on the mechanism.

The first peak and valley price. As the stored energy is low when the "charge storage," peak "electricity supply" peak and valley price difference is a basic source of income for investment in energy storage. Europe, the United States, Japan and other countries and regions mature peak and valley price policy. canon NB-5H battery In China, except in very few areas have pockets of the TOU rate, the basic failure to implement TOU pricing. There is no peak and valley spread, who is willing to invest in energy storage?

The second is electricity storage. As the energy storage technology to increase power generation equipment use hours and power quality, enhanced power peaking capacity, saving the system investment, promoting a new energy development, there are significant effects of emissions, therefore, should establish a separate storage price policy. But our country is currently no specific storage price of the existing pricing system, the storage of construction and operating costs can not find a channel to divert.

Lack of incentive policies. Although in recent years, China's technological achievements in large-capacity storage and a considerable accumulation of talent, and vanadium flow batteries and lithium-ion batteries and other energy storage technology is a world leader, or even related companies products have been recognized in foreign markets, but the China has not yet an application demonstration project, the Government's large-capacity storage technology, R & D investment is also very small, let alone the application of financial subsidies. In contrast, canon NB-4L battery the U.S. and Japan and other countries to support large-capacity storage technology research and development and industrialization of the intensity of the major applications was unprecedented.

The U.S. government has supported a large-scale energy storage technology to locate new energy development, strategic technology, in the first half of this year has allocated two billion U.S. dollars in support of including a large-scale energy storage battery technology, including research and development. Developed in the United States Department of Energy on the smart grid scheme, the energy storage technology projects, more than all the other items, up to 19, financial support to the greatest.

According to the adoption in 2009 of "stored energy bill," the United States for high-capacity storage investment will provide 20% of the investment tax deductible, for families, factories, commercial centers, distributed renewable energy applications in the storage section, also provides 20% of the investment tax deduction. California also meet the technical requirements, and wind power or fuel cell energy storage system supporting the construction of two U.S. dollars / watt of additional subsidies. In addition to direct support of the Government of Japan early stage research and development, the recent years to support a large number of demonstration projects to encourage large-capacity storage technology popularization and application.

Supporting the management rules and technical standards missing. canon NB-4L battery In addition to economic incentives, the strict technical standards and standardized management, but also drive the development of energy storage industry, an important driving force. Such as Spain and other countries stipulates that all wind power in the Internet before fans to contribute to the power grid to provide short-term forecasts curve and the power curve, the error can not exceed a certain percentage, or they will be punished.

This will take the initiative to adopt Daobi power forecasting techniques and energy storage technology to realize new energy power generation and grid construction of the benign development. But our attitude towards wind power network has not yet mandatory processes and technical requirements, many enterprises believe that as long as the issue of wind power electricity, regardless of how many pros and cons, power grids must be received in full, in this case, the power generation companies have no incentive use of natural energy storage technology.

The promotion of large-capacity storage industry development policy recommendations

 

The stored energy and new energy development plan simultaneously. In accordance with the grid system to achieve safe operation and optimum efficiency canon NB-5L battery of the principle in the planning of new energy power generation and grid transmission lines at the same time, should propose appropriate storage solutions, clear the scale of development and construction of storage areas and so on. To try to prevent the already in the field of wind power and solar power generation there hair, transmission, storage gap phenomenon.

The implementation of TOU pricing and tariff policy of energy storage. Peak and valley price might be somewhat different in different regions, but it should be as far as power grid peak load shifting and to attract investment and create more space for storage. Storage tariff may refer desulfurization of thermal power electricity prices, electricity prices in the original on the basis of new energy to add a few PCT money, and the formation of a new energy package containing storage tariff. Under the guidance proposed in the government tendering mechanism for the formation of through market competition.

Specification requirements and new energy power generation technologies, canon BP-511 battery and network management. States should put on the new energy and nets mandatory technical standards, to build and network certification and testing system. Implementation of the new short-term forecasts of energy generation to contribute to the reporting system to improve the capacity and the level of short-term forecasts. Complete the full acquisition system, power companies meet the requirements of electricity network should be received promptly and in full, to poor power quality, power generation, large forecast errors of the new energy power generation option to receive, and establish the appropriate punishment mechanism.

To encourage investment diversification. Investment in large-capacity storage power station is not appropriate to apply to countries currently for pumped storage power station can only be made by a wholly-owned grid company building, does not allow other investors equity requirements. In rationalizing the return on investment mechanism to standardize the technical requirements under the premise of network access should be encouraged power producers, power companies, clients, third-party independent energy storage enterprises of any conditional investors to invest in energy storage.

To intensify over arrangements for storage demonstration projects. Through the implementation of a number of energy storage demonstration projects provide an important enterprise for its own energy storage engineering practice opportunities for the future accumulation of large-scale application of technical data and operational experience.

In the demonstration project, in conjunction with the performance of various types of energy storage technologies, in a comprehensive assessment based canon NB-2L battery on the specific uses the appropriate choice of energy storage technology. The early demonstration projects may be first with wind power, solar power combine to explore an integrated model of reservoir scenery. Electric

Network is an important demonstration project organizers and builders, national authorities, upon request, and support the construction of several demonstration projects Grid Corporation of China. Need to be further clear that the sources of technology demonstration projects should be based on the main domestic enterprises, mainly to support their own technological development, can not model the process of using financial subsidies to imply support for foreign parts or the whole machine works.

Increase large-capacity storage technology, R & D investment to encourage diversification of energy storage technology. Energy storage technology research should be ahead of demand for development, and can not wait until a bottleneck when consider increased. Should be a large-scale energy storage technology research and its industrial application of major projects included in the national science and technology.

Since there is currently no fully qualified for an energy storage technology, the requirements of a variety of application areas, and therefore focus on support for vanadium redox flow batteries, lithium-ion batteries key technologies, we should also encourage and support other energy storage technology development. canon NB-1L battery Further increase of the energy storage technology, investment in basic research and encourage original innovation, master intellectual property.

Building a base lithium battery recycling

2015, 1 million hybrid / electric vehicles, cars that will be into the streets of the United States. Laptop Battery In this replacement behind the revolution, a more thorny issues that must be resolved: the battery recall problem.

Recently, the U.S. Department of Energy grant 95 million U.S. dollars to support California a recycling company, to enhance the productive capacity of lithium batteries. This battery can be for the international market, a variety of new hybrid / electric cars energy power.

A US-based recycling company, equipped to handle different types of lithium battery capacity. They use the funds, in the Lancaster and Ohio, investment in plant and equipment, production for automotive batteries. The plant, not only the production of hybrid / electric vehicles commonly used in nickel-metal hydride batteries, also produce large-capacity lead-acid battery. Last month, 2.4 billion U.S. dollars for the fund launched to stimulate and support the U.S. domestic automotive battery manufacturing and development. Allocation of funds to the company, is part of the plan, Sony CCD-TR2 battery but also President Obama to change the country dependent on imported oil and battery operations component.

"The U.S. market for hybrid / electric vehicle demand continues to grow, and we will be a safe, environmentally friendly way of recycling waste batteries." Tuodi Ke Yang, the company's executive vice president says.

Last month, Nissan Motor Company announced a new zero-emission electric vehicle "leaf", General Motors has released a "Chevrolet Volt", which are used in battery electric vehicles in 2010, after the completion of the mission, the final ownership of land is likely to This company is the United States Lancaster factory. There, they were processed into a variety of metal materials, such as cobalt, copper, nickel, lithium carbonate.

The company's Canadian subsidiary, Sony CCD-TR3 battery based in British Columbia plant, has begun to recover from a variety of devices, lithium batteries, such as notebook computers, industrial equipment, Tesla Motors all produced electric double convertible. Lithium-ion batteries be recycled before it gets frozen to -325 degrees Fahrenheit to remove the lithium metal, and then cut, separation.

Although lithium metal in the free market is now very difficult to sell, but the lithium battery inside other metal elements, such as nickel, cobalt, are very precious, if the lithium-ion battery directly to the garbage dump on the pity. Kojan also said Lancaster extract lithium carbonate plant has the capability for the production of automotive battery recycling, so if there is market demand.

Other recyclers, and actively respond to the new changes in electric vehicles

Belgium-based Umicore, a spokesman for Sony NP-F550 battery (Tim Weeks) said that with the increased demand for electric vehicles, car battery metal also increases the demand for raw materials, such as cobalt, nickel, manganese. They have also applied for a U.S. fund for the promotion, production and eco-car batteries, but have not yet been approved.

"We believe that one day the electric powertrain will be achieved." Vickers said. The company hopes to by 2015, hybrid (electric) vehicles to reach 5% market share, so that is bound to bring new opportunities for the recycling industry.

Umicore the face of rapid expansion of the electric car market, is actively looking for their market position.

Sony NP-QM91 battery (Carlos Ghosn), has just opened a new electric car leaves the mystery of the Nissan's CEO told us that by 2020 electric cars will reach 10% market share in reference to last year, car sales, which is equivalent to sold 650 million electric vehicles. "

But the London-based Asian automotive intelligence advisory company, managing director of Ashe temperature Dakota (Ashvin Chota) think this estimate too optimistic. Even if the electric cars at competitive prices, by 2020, market demand for electric cars was only a few millions only. Automotive consultancy services company expects 2015 production of electric vehicles will reach 289,000.

Umicore experimental base in Sweden have begun to recover a small amount of lithium batteries, the lithium carbonate extracted can be used as an additive used in the construction industry. However, with the lithium metal market need to grow, the company expects its U.S. recycling plants can be provided directly to the battery manufacturers lithium metal.

Although the recovery of lithium is not much value, but for recycling companies, lithium batteries and nickel-metal hydride particles have the same battery Sony NP-QM90 battery recycling value. "More importantly, the lithium-ion battery more economical. Vickers said.

In addition, from the perspective of environmental protection, recycling battery materials, but also very meaningful. Although the lithium batteries and lead-acid batteries is different it does not contain corrosive chemicals. However, if allowed to pile up in the garbage dump, not only wasteful, but there is the potential risk of groundwater contamination.

In Keyang view, the recovery of lithium-ion battery, which the material is more valuable, and now a conclusion is premature. Because developers and manufacturers of the battery is still very confidential formula. Recall the batteries, only a few people through a limited open channels learned of the product formulations. He said that in the new round of lithium-ion battery replacement, he will not know more than the general population.

A large number of lithium metal, the flow of surface

Lithium produced mainly in Bolivia, Chile and China. Sony NP-FM71 battery It is said that the construction of the car battery recycling bases, although they would help the United States out of the "peak oil theory" of the shadow, but will inevitably fall into the "lithium metal peak theory" trap.

As the global economic recession, the demand for lithium inevitably have been pressed, but, according to TRU predicts that by 2013, world lithium demand is rising. Toronto, an industry research organization, said that with the increased demand for electric vehicles, to 2017, or even earlier, the lithium will be in short supply.

From Chicago, Argonne National Laboratory analyst Linda Gu Jamison (Linda Gaimes) think this is too early to worry about. He is conducting research activities for a period of 4 years to study the energy lithium battery can power the United States over to the battery-driven era.

"Even if we have a very convincing electric vehicle plans, but we still do not intend all use lithium batteries." Jamison said. His research indicates that at least 2050,Sony NP-QM51 battery lithium production was up to go to market equilibrium. This data would mean that by mid-century, the United States would be about 500 million electric cars, in other words, car companies have to spend about 21 million sold.

If people are worried about the supply of battery materials, particularly cobalt, precious because it is several times more than lithium. Jamison told people that this fear is totally unnecessary. Because of the near future, it may not re-use of this material. On the other hand, according to the U.S. Geological Survey data show that the United States rely mainly on foreign imports of lithium. The U.S. Currently, only one company in the Nevada desert, the use of extracted lithium metal halide technology. More than 85 percent of the world's lithium reserves in Bolivia, Chile and China.

Jamison's research shows that if the effective recycling of lithium batteries, lithium-ion batteries used in the production of lithium needs to be reduced by half.

"If the United States to seriously implement the recovery program, the lithium can become Sony NP-QM70 battery self-sufficient." Gaines said. "Ideally, the overall separation of the battery, clean-up and then as a new battery recycling."
