Title:
POLYMERIC ELECTROLYTE MEMBRANE FOR LITHIUM SECONDARY BATTERIES PREPARED FROM STAR-SHAPED INORGANIC POLYMER COMPOSITES AND LITHIUM SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2012/137995
Kind Code:
A1
Abstract:
The present invention relates to manufacture of a solid-phase polymer, polymeric electrolyte membrane for a lithium secondary battery using a lithium ion conducting polymer containing lithium salts as an electrolyte. Star-shaped polymers are comprised on the inside of high density polymer chains which become less dense toward the outside of the polymeric chains which reduces the crystallinity of the PEO based polymer chains and helps improve the flow within the polymer chains and high ionic conductivity can be expected.
