CLPA series

Binders for LIB

This binder has been developed for use with high capacity Si type anodes. Si type is the emerging anode technology for next generation lithium ion rechargeable batteries. CLPA inhibits the collapse of the negative Si electrode that is caused by the repeated volume change during charge/discharge.
