Title:
LITHIUM-ION-CONDUCTIVE GEL-FORM ELECTROLYTE AND POLYMER LITHIUM-ION SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2003/075391
Kind Code:
A1
Abstract:
A lithium-ion-conductive gel-form electrolyte having high ionic conductivity at low temperatures. A preferred embodiment comprises a polymer, a lithium salt, and an organic solvent, and is characterized in that the polymer is a copolymer obtained from an ingredient which shows ionic interaction, an ingredient which forms chemical crosslinks, and an acrylic ester and/or methacrylic ester. Also provided is a polymer lithium-ion secondary battery which comprises a positive electrode, a negative electrode, and a gel of the lithium-ion-conductive gel-form electrolyte interposed between the electrodes.
