Teijin Signs Comprehensive License Agreementwith SEMCORP to Develop Solvent-based Coating
Separators for LiBs
Tokyo, Japan, December 22, 2020 --- Teijin Limited announced today that it has signed
a technical license agreement with Shanghai Energy New Materials Technology Co.,
Ltd. (SEMCORP), a leading producer of competitively priced base films for lithium-ion
secondary batteries (LiBs), to manufacture solvent-based coating separators used inLiBs for electric vehicles and additional applications such as electronic devices andenergy storage systems. The comprehensive agreement also includes Teijin’s
development of new solvent-based coating separators.
Through the agreement, Teijin expects to strengthen its market presence by offering
successively new separators for LiBs. Teijin is committed to steadily improving its
coating technologies for extra safe and efficient separators. For SEMCORP, theagreement will allow the company to expand its manufacture and sale of solvent-based
coating separators that meet the functionality and safety needs of customers.
The agreement covers Teijin’s proprietary technologies and patents for coating andproduction processes used in solvent-based coating separators, including aramid- andfluorine-based coatings offering excellent performance and safety. Aramid-based
coatings also provide added heat resistance for superior safety.
In addition, in a separate contract covered under the agreement, Teijin has been
entrusted by SEMCORP to develop new coating separators for high-capacity,extra-safe LiBs.
The growing popularity of EVs is accelerating demands for LiBs capable of safe
performance even during long-distance driving. In November 2019, Teijin andSEMCORP concluded a technical license contract for solvent and fluorine-based
coatings used in EV LiB separators. These separators, which incorporate Teijin's
high-level coating technologies and are produced with SEMCORP’s cost-competitive
base films, have been meeting market demands while earning high evaluations fromcustomers.
