POLYSILOXANE RESIN CONTAINING SINGLE-ION CONDUCTOR AND A FILM FOR LITHIUM SECONDARY BATTERY USING THE SAME

摘要

PURPOSE: A polysiloxane polymer resin containing a mono-ionic conductor and a film for lithium secondary batteries are provided to maintain high portability and ion conductivity and enhance electro chemical stability of polyelectrolytes. CONSTITUTION: A polysiloxane polymer resin containing a mono-ionic conductor comprises a polysiloxane precursor, polyfunctional polyethylene oxide, mono-ionic monomers and lithium salt. The polysiloxane is manufactured by a coupling reaction and hydrogen removal polyethylhydrosiloxane and allyl polyether under a platinum catalyst. The polymethylhydrosiloxane has a molecular weight of 1,700-10,000 g/mole and the allyl polyether has a molecular weight of 230-400 g/mole.
