High-capacity Film-type Lithium-ion Battery Developed Using Coating Process


- Achieving world-class triple capacity / higher safety / ten times faster production speeds – 

The R&D Center (Director: Satoshi Uenoyama) of Sekisui Chemical Co., Ltd. (President: Naofumi Negishi, hereinafter called "Sekisui Chemical") has developed a high-capacity film-type lithium-ion battery using a coating process that has simultaneously tripled its capacity (compared to other Sekisui Chemical products), increase its safety (as a result of standard safety testing, e.g. no problems with nail penetration tests or crush tests) and speeded up production by ten times (compared to other Sekisui Chemical products).

Sekisui Chemical has carried out materials technology and process technology development towards realizing the following.
