Electrolyte membrane made of resin composition comprising polymer formed by branching of multifunctional block copolymer comprising polypropylene oxide block and polyethylene oxide block and ionic electrolyte

摘要

The present invention relates to a support made from a resin composition containing a polymer in which a multifunctional block copolymer including a polypropylene oxide block and a polyethylene oxide block are bound to each other; An electrolyte membrane including the support and the ion conductive electrolyte supported on the support; A method of producing the electrolyte membrane; And a battery and an ultra-high capacity capacitor including the electrolyte membrane. The support prepared from the polymer formed by combining the polyfunctional block copolymer including the polypropylene oxide (PPO) block and the polyethylene oxide (PEO) block of the present invention had a physical strength improved by including the PPO block, The electrolyte membrane produced from the electrolyte membrane has a high ionic conductivity, and the electrolyte membrane having a high ionic conductivity has a high ionic conductivity. A stable electrolyte membrane can be provided. Therefore, the electrolyte membrane can be usefully used in secondary batteries and ultra-high capacity capacitors.
