ELECTROLYTE MEMBRANE MADE OF RESIN COMPOSITION COMPRISING POLYMER FORMED BY BRANCHING OF BLOCK COPOLYMER COMPRISING POLY(PROPYLENE OXIDE) BLOCK AND POLY(ETHYLENE OXIDE) BLOCK, AND IONIC ELECTROLYTE

摘要

The present invention relates to a supporting body made from a resin composition including a polymer made from by which block copolymers with a polyethylene oxide block and a polypropylene oxide block are connected to each other in a branch connection, an electrolyte membrane including the supporting body and ionic conducting electrolyte supported in the supporting body, a manufacturing method of the electrolyte membrane, and a battery and a supercapacitor including the electrolyte membrane wherein the supporting body manufactured by which block copolymers with a polypropylene oxide (PPO) block and a polyethylene oxide (PEO) block are connected to each other in a branch connection has an excellent capacity to include an ionic conducting electrolyte, so the manufactured electrolyte membrane by using the supporting body has good ionic conductivity and improved physical strength due to the PPO block while maintaining stability due to cross-linking bond even at high temperatures. Therefore, the electrolyte membrane can be used in secondary batteries and supercapacitors.
