New Lithium-ion Battery in China Will Be Industrialized

From the 9th International Conference on New lithium battery for Electric Vehicles(ABAA 9), it was learned that by 2020, China's new lithium-ion battery will be industrialized, power batteries will be intelligent manufactured, and product performance will be greatly improved.

According to Bianshuguang, deputy director of the High-tech Research and Development Center of the Ministry of Science and Technology, the production of lithium-ion power batteries in the world is mainly concentrated in China, Japan, and South Korea. Among them, the number of Chinese companies is the largest and the production capacity is the largest.

At present, China has formed a relatively complete lithium-ion power battery industrial chain system, mastered the power cell formula design, structural design and manufacturing technology, the production line has gradually from semi-automatic to fully automatic large-scale manufacturing transition. Bianshuguang said.

Bianshuguang pointed out that China's lithium-ion battery companies still have a large gap with foreign advanced companies in high-end materials and related basic research, as well as battery safety, reliability and system management technology.

According to the introduction, during the "Twelfth Five-Year Plan" period, the energy ratio of Chinese lithium-ion power batteries reached 160 watt/kg or more, and the cost was less than 3 yuan/watt-hour. According to "Made in China 2025", by 2020, China's lithium-ion batteries will have a specific energy of 300 watt/kg.

Lithium-ion battery technology, which is widely used in new energy vehicles, greatly influences the development of new energy automobile industry

"For quite some time to come, energy conservation in China will focus on popularizing new energy vehicles such as plug-in hybrid vehicles and pure electric vehicles. Therefore, the next step is to improve the intelligent manufacturing level of power batteries, improve the verification and testing methods and standard system, which is the key task for the development of power batteries in China. " said Bianshuguang.
