Title:
POLYMER ELECTROLYTE AND LITHIUM POLYMER BATTERY
Document Type and Number:
WIPO Patent Application WO/2012/132957
Kind Code:
A1
Abstract:
A polymer electrolyte which comprises a hyper-branched polymer which is produced by polymerizing a monomer component comprising a monomer (A) having at least two radically polymerizable double bonds in the molecule in the presence of a polymerization initiator in an amount of 5-200 mol% relative to the amount of the monomer component and also comprises an electrolyte salt, wherein the monomer (A) is a compound having a vinyl group and/or a (meth)acryl group. Provided are: a polymer electrolyte which can exhibit good ion conductivity without the need of being impregnated with an electrolytic solution and has superior shape-retaining properties and mechanical strength compared with those of electrolytes each impregnated with a solvent; and a lithium polymer battery produced using the polymer electrolyte.
