ORGANIC-INORGANIC HYBRID BLOCK OR RANDOM COPOLYMER AND POLYMER ELECTROLYTE FOR LITHIUM SECONDARY BATTERY USING THE SAME AND LITHIUM SECONDARY BATTERY

摘要

PURPOSE: A block or random type organic-inorganic hybrid copolymer is provided to provide a solid phase polymer electrolyte membrane with excellent mechanical properties and ion conductivity. CONSTITUTION: A block or random type organic-inorganic hybrid copolymer is indicated in chemical formula 1 or 2. A manufacturing method thereof comprises: a step of manufacturing poly(ethylene glycol) methyl ether methacrylate by using reversible addition-fragmentation chain transfer polymerization; a step of mixing the poly(ethylene glycol) methyl ether methacrylate, polyhedral oligomeric silsesquioxane, and azobisisobutyronitrile; and a step of manufacturing the block or random type organic-inorganic hybrid copolymer by using reversible addition-fragmentation chain transfer polymerization.
