Block-graft copolymer, self-crosslinked polymer solid electrolyte and composite solid electrolyte manufactured through use of the block- graft copolymer, and solid cell employing the composite solid electrolyte

摘要

There are disclosed a self-crosslinked polymer solid electrolyte, a composite solid electrolyte, and a method of manufacturing the same. A high-energy ray is irradiated to a block-graft copolymer composed of a polymer block chain A represented by formula I and a polymer block chain B represented by formula III in order to crosslink the entire the system. A nonaqueous electrolytic solution is then added to the block-graft polymer to obtain a self-crosslinked polymer solid electrolyte. The self- crosslinked polymer solid electrolyte and an electrically insulating material are combined to obtain a composite solid electrolyte. ##STR1##
