LIQUID POLYMERIZABLE COMPOSITION FOR PRODUCING SOLID ELECTROLYTES AND METHOD FOR ITS CURING Russian patent published in 2004 - IPC

Abstract RU 2234168 C1

FIELD: electrochemistry; solid electrolytes for various electrochemical devices.

SUBSTANCE: proposed liquid polymerizable composition incorporating reactive compounds and nonaqueous solution of lithium salt has 1.0 to 1.5 M of nonaqueous lithium salt solution as well as oligourethan methacrylate and polypropylene glycol monomethacrylate as reactive compound; total amount of oligourethan methacrylate and polypropylene glycol monomethacrylate in nonaqueous solution of lithium salt amounts to 12 - 17 mass percent and their mass proportion is 1 : 1 - 1.1. Method for curing proposed composition includes addition of 1.9 - 2.1 mass percent of polymerization photoinitiator per total amount of oligourethan methacrylate and polypropylene glycol monomethacrylate; curing is conducted under action of ultraviolet rays.

EFFECT: enhanced strength of solid electrolytes and reduced production process time.
