- 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.
