Development/technology licensing of batteries for automotive (EV)

Pioneer of Li-ion batteries for EVs produced in China
Contributed to mass production by conducting "principle prototyping/functional prototyping/pre-production prototyping" as part of process development

Customer needs/background

As part of China's national policy, we are entrusted with the development and process development of lithium-ion batteries, which are the core of EV development.
We were involved in the establishment of standards for batteries related to EVs in China, and we also set up a mass production plant for EVs in China.
In addition, we participated in the domestic EV development in China and were in charge of the battery pack part of the EV that was prototyped and developed in Japan.
