Lithium-ion Batteries PVDF Resin
1. Product Introduction
PVDF exhibits great chemical resistance, electrochemical stability, oxidation resistance and outstanding resistance to electrolyte, which made it a well- recognized binder material for lithium-ion batteries .
Bestmake development of PVDF for batteries dates back to 2005, it owns a professional team with strong background of materials research, production, evaluation and promotion. 2510 is specially used for 3C digital products and energy storage batteries. 2536 is used for high-end 3C digital products and LFP power batteries. 25628, a kind of high performance copolymer products, exhibits excellent in ternary power LIBs. We are also a pioneer in terms of high-end PVDF adhesives developing. New product 25630 and 253 is about to come out, which are respectively applied for high-end ternary and LFP power LIBs. Both have been evaluated by downstream customers with excellent performance .
