Abstract
The present invention relates to a polyalkylene oxide based polymer composition for solid polymer electrolytes having superior mechanical properties and ionic conductivity by comprising a cross-linking agent with at least two functional groups of phenyl alkyleneglycol acrylate substitited in core molecules; a softener of polyalkyleneglycol alkylether alkyl(metha)acrylate; a plasticizer of polyalkyleneglycol dialkylether; a initiator and lithium salt thus can be useful as an electrolyte for a high capacity lithium-polymer secondary battery for load leveling or electric vehicles as well as an electrolyte for a small capacity lithium-polymer secondary battery for portable information terminals such as a cellular phone and a notebook computer, and electronic products such as a camcorder.
