According to Shuguang, deputy director of the High Technology Research and Development Center of the Ministry of Science and Technology, the current production of lithium-ion battery in the world is mainly concentrated in China, Japan, and South Korea, among which Chinese companies have the largest number and the largest production capacity.
At present, China has formed a relatively complete lithium-ion battery industry chain system, mastering the formulation design, structural design and manufacturing process technology of power batteries, and the production line has gradually transitioned from semi-automatic to fully automated large-scale manufacturing. Twilight said.
Dawning pointed out that China's lithium-ion battery companies still have a large gap with advanced foreign companies in high-end materials and related basic research, as well as battery safety, reliability and system management technology.
According to reports, during the "Twelfth Five-Year Plan" period, China's lithium-ion power battery has a specific energy of more than 160 watt-hours per kilogram, and the cost is less than 3 yuan / watt-hour. According to "Made in China 2025", by 2020, the specific energy of lithium-ion batteries in China will reach 300 watt-hours/kg.
As a power battery widely used in new energy vehicles, lithium battery technology has greatly affected the development of the new energy automobile industry.
"For a long time in the future, China Energy Conservation 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 and improve the verification test methods and standards system. It is a key task for the development of China's power battery," said Shuguang.
