Lowest indicator 300 Wh/kg power battery industry "action plan" landing

Recently, the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Science and Technology, and the Ministry of Finance jointly issued the "Action Plan for Promoting the Development of Automotive Power Battery Industry" (hereinafter referred to as "Action Plan"), so that the development of the power battery industry has a more definite development goal. With direction.

The "Action Plan" pointed out that after more than ten years of development, China's power battery industry has made considerable progress, but the current product performance, quality and cost are still difficult to meet the requirements for the promotion of new energy vehicles, especially in the basic key materials, system integration technology, manufacturing There is still a big gap between the international advanced level in terms of equipment and technology.

Compared with previous policies issued by the Ministry of Industry and Information Technology, such as the "Automotive Battery Regulatory Industry Specification", the "Action Plan" issued this time refers to the pain points in the power battery industry, sets a clear development goal, breaks down key tasks, and proposes guarantees. Measures to further promote the rapid development of the power battery industry.

Lithium battery has a significant increase in specific energy

The "Action Plan" proposes that the main direction of China's power batteries is to continuously improve the performance, quality and safety of existing products, further reduce costs, ensure the supply of high-quality power batteries by 2018, and vigorously promote the development and industrialization of new lithium-ion power batteries. In 2020, large-scale applications will be realized; efforts will be made to strengthen the basic research of the new system power battery, and to achieve technological change and development testing in 2025.

The “Action Plan” also strictly stipulates the timeline of the key indicator of the specific energy of the power battery: By 2020, the specific energy of the new lithium-ion power battery will exceed 300 Wh/kg; the system specific energy will strive to reach 260 Wh/ Kg, the cost is reduced to 1 yuan/Wh, the use of environment -30 °C to 55 °C, with 3C charging capability.

For the above requirements, Han Guangxin, deputy general manager of Henan Universal Solar Energy Technology Co., Ltd., told the “China Automotive News” reporter: “By 2020, the minimum specific energy index for lithium-ion battery cells is 300 Wh/kg, which is large. Most companies have great challenges.” According to a survey conducted by the reporter, the current specific power consumption of Panasonic battery packs for Tesla models is 230 watt-hour/kg, and the Samsung SDI has a single-cell specific energy of 250 watt-hour/kg. "The Panasonic NCA series (nickel-cobalt-aluminum) battery has achieved the ultimate in specific energy." Han Guangxin said that if the specific energy of lithium-ion power battery cells is increased from 230 watt-hour-hours/kilogram, safety parameters cannot be ignored. In-depth study of basic materials and improved battery system integration technology. ”

Strengthen new system battery development

One of the nine key tasks put forward in the Action Plan is the implementation of a power battery upgrade project, which is to support the research and development of power batteries through national science and technology plans (special funds, funds), and to achieve a specific energy of over 300 Wh/kg in 2020. Continuously improve product performance, speed up the implementation of high-level product loading applications; encourage leading battery companies to collaborate with upstream and downstream resources, and concentrate on breakthroughs in materials and components, battery cells, and system key technologies to significantly improve the performance and safety of power battery products. We will strive to realize the industrialization of new lithium ion products and vehicle applications at 350 watt-hour/kg for the monomer and 260 watt-hours/kg for the system.

Liu Guanwei, a professor at Tsinghua University who has long been engaged in power battery research, believes that the 2020 lithium battery specific energy index set in the “Action Plan” should not be a problem for companies to sample, but it is not difficult to really enter the mass production stage.

Liu Yanlong, secretary-general of the Chinese Chemical and Physical Power Industry Association, also expressed similar views when interviewed by a reporter from China Automotive News. He stated that it is very challenging to realize the industrialization of power batteries based on the above standards.

In fact, the "Action Plan" also revealed information in another aspect. At present, the government's attitude toward the development of the power battery industry is all-dimensional and multi-dimensional. It is not limited to the application of certain materials, but allows "hundred flowers and hundreds of schools of thought to contend". .

The key tasks set forth in the Action Plan include strengthening the research of the new system power battery: through the national key R&D programs and the National Natural Science Foundation, encourage universities, research institutes, key enterprises, etc. to collaborate in the development of new system power battery products. Actively promote the research and engineering development of new system batteries such as lithium-sulfur batteries, metal air batteries, and solid-state batteries. This task also quantifies the performance indicators and time nodes. By 2020, the specific energy per unit cell will reach 400 Wh/kg and will reach 500 Wh/kg in 2025.

Han Guangxin also emphasized to the reporter of China Automotive News that in the future, automotive battery technology must move toward high safety, long life, high specific energy and high power. To this end, China's automotive power battery companies should strengthen technological innovations, such as the application of nanotechnology in the field of power batteries.

The "Action Plan" also proposes that accelerating the development and industrialization of key equipment is also a key task. Through the major short board equipment upgrade project, promote the industrialization of intelligent manufacturing equipment, encourage the combination of power battery production companies and equipment manufacturers, explore the establishment of cooperation models for capital and risk sharing, and strengthen the coordination of key equipment manufacturing equipment. To tackle the problems, promote the industrialization of digital manufacturing equipment and improve the stability and reliability of equipment accuracy and the level of intelligence, and effectively meet the demand for power battery manufacturing and resource recycling. Han Guangxin said: "There is still much room for improvement in key equipment areas."

"In addition to the continuous support of the national policy, we must also increase the intensity of research and development of new materials and ensure the development of industrialization in terms of technology development, manufacturing, and the degree of intelligence." Liu Yanlong told the "China Automotive News" reporter.

Building open and shared innovation platform

In the “Action Plan”, the construction of a power battery innovation center was put on the agenda. The project was led by the Ministry of Industry and Information Technology. The "Action Plan" pointed out that we must promote large-scale small and medium-sized enterprises, universities, research institutes, etc. to build collaborative innovation, open and shared power battery innovation platform, and guide and support the establishment of a market-oriented innovation center for advantageous resources. The main purpose of the center is to speed up the construction of internationally advanced R&D, pilot development, test verification, and industry service capabilities. Major key common technologies, basic technologies, and forward-looking technologies such as power battery key materials, single cells, and battery systems will be developed. Research, as well as research on the layout and reserves of intellectual property rights, provide support to the industry in terms of technology development, standard setting, personnel training, and international exchanges.

In this regard, Han Guangxin is looking forward to. However, he also said: "The power battery innovation center should be based on the natural sciences, study the applicable technologies and processes, cultivate outstanding talents, and must not become a 'catwalk show' that sets the threshold and supports the scene." Liu Yanlong told the "China Automotive News" reporter He expressed the hope that the positioning of the Innovation Center will be clearly defined and differentiated. He said: "At present, China's mainstream power battery companies have built their own research centers, and the investment is not small." In addition, Liu Yanlong is also very concerned about the innovation center's technical results can make every enterprise truly benefit.

The power battery is the heart of the electric vehicle and is the key to the development of the new energy automotive industry. The government has always attached great importance to the improvement of power battery performance and industrialization. "In recent years, the state has subsidy and support policies for new energy vehicles and key parts and components. Enterprises should cherish the opportunity to develop their internal strengths so as not to miss the opportunity for great development," Liu Yanlong confided.

“The “Action Plan” will play a positive role in guiding and encouraging the power battery industry.” According to Han Guangxin, the “Action Plan” can clarify the direction for the development of China’s power battery industry, guide enterprises to take detours, and achieve greater effectiveness. Promote the development of new energy automotive industry. Other industry sources also pointed out that this document is a far-reaching policy revision that will have a far-reaching impact on the power battery industry in the next few years. It not only shows the government's determination and attitude toward the development of new energy sources for battery power in the automotive industry, but also shows enough ambition and confidence. , contains potential benefits for the development of the industry.
