At the end of June, a development seminar on new energy vehicle power lithium-ion batteries was held in Beijing, and the Minister of Industry and Information Technology and the two deputy deputy director participated. At the meeting, in addition to discussing the development strategy of the dynamic lithium-ion battery, the National Power Lithium Ion Battery Innovation Center is also established, which is dedicated to the key technical problems that hinder the development of the powerful lithium-ion battery industry. On the eve of the new energy car broke out, this innovation center was given a hopes.

Power lithium-ion battery meets bottleneck 2015 new energy my country's new energy vehicle output exceeds 300,000 units, my country has become the world's largest new energy auto market, and it is expected that the number of market insurance will reach 5 million units in 2020, and the output will reach 2 million. , More than 100GWH for power lithium-ion battery. Regrettably, when my country's new energy auto production scale is rapidly expanding, the research and development of dynamic lithium-ion batteries cannot keep up with the pace in time.

At present, it has become a bottleneck that restricts further development of new energy vehicles in my country. Xiong Boqing, Vice President, Beijing Nonferrous Metal Research Center, told reporters that my country's independent research and development of dynamic lithium-ion battery is weak, and at the same time, it is expensive, which greatly affects the popularity of new energy vehicles. How to solve the production and technology of the bottleneck and lithium-ion battery? Taking a 1.

5-ton new energy vehicle as an example, if it reaches 400 kilometers of charging battery life, under the current technical level, only the battery weight is close to 600 kg, the battery manufacturing cost is 150,000 yuan, plus The price of the car, a general new energy car price is nearly 400,000 yuan, and the general consumer is difficult to accept. At present, it relies on huge financial subsidies support, but it is difficult to continue for a long time. Therefore, while how to reduce the battery weight, do not reduce the battery life, and reduce the price, test the breakthrough of battery technology.

It is reported that the domestic power lithium-ion battery is important to have three bottlenecks: the first ratio is low; the second battery is high; the third battery system is not enough, about 5 ~ 8 years, the battery is all eliminated. On the other hand, frequent electric vehicle explosions and combustion events also make battery safety problems more prominent. Safety is the fundamental guarantee of future development of new energy vehicles, with power lithium-ion battery is key joint.

If you don't do it, it will seriously dampen consumer confidence and affect the development of the entire industry. Forming a combined effort to break the breakthrough, in the technical research and development of the power lithium-ion battery, Japan South Korea has been going in front. "Japan and South Korea is technically more advanced for approximately 3 to 5 years.

Now our lithium electricity is still in the laboratory stage, Japan and South Korea has taken engineered samples. Xiong Boqing said. How to catch up with them, realize the curve overtaking, a major challenge in front of my country's powered lithium-ion battery companies.

"The first maximum integration of the resources of the whole industry, including the establishment of the national power lithium-ion battery innovation center, in addition to more than ten shareholders set up the powerful lithium-ion battery innovation alliance, and collect domestic universities, research institutes, including companies, have gathered together 560, in the alliance established a good intellectual property sharing mechanism, jointly contributing wisdom, sharing the future five-year power lithium-ion battery development results. Xiong Boqing said. A maximum weakness of my country's motivational lithium-ion battery production company is that the R & D capability is not strong.

The company is fighting, it is difficult to form a cooperation. Xin Guobin, deputy director of the Ministry of Industry and Information Technology, frankly: Overall, my country's dynamic lithium-ion battery industry has also facing problems such as small, scattered, weak, weak, research and development, and lack of labor, and the comprehensive strength and international advanced companies have some gap, product technology Level, industrial innovation ability and market competitiveness need to be improved. It is understood that my country's powered lithium-ion battery production company is more than four or five hundred industrial dispersions, and universal strength is weak.

The 100,000 kilowatt battery production capacity company only ten, the largest company BYD's market share is less than 15 %. Only technical breakthroughs can only be achieved in effectively integrated domestic research and development power. With the support of the Ministry of Industry and Information Technology, the National International Bureau of Automotive Lithium Ion Battery Research Institute was established in September 2014 to build a domestic dynamic lithium-ion battery R & D center, which is completely independent by the company.

At the establishment of the research, there were 9 units of funding 540 million yuan, the Ministry of Science and Technology, the State-owned Assets Supervision, Ministry of Industry and Information Technology, and the Development and Reform Commission. "This has created a good profit model. Through technology radiation, technology transfer, good benefits can be achieved in the next five years, this benefit can support the research and development of powerful lithium-ion batteries.

Xiong Boqing said. In the original vice president of the Chinese Academy of Engineering, the leader of the expert group of the National Manufacturing Innovation Center, the establishment of the dynamic lithium-ion battery innovation center, "important is a centralized innovation ability, concentrate high-end R & D team, forming a working force, in power lithium ion battery Breakthrough in core community technology. "According to him, it is necessary to face the gap in the development of the dynamic lithium-ion battery, especially compared with Japan, South Korea, my country's dynamic lithium-ion battery is 30% ~ 40%, and the endless mileage is 30% ~ 40%.
