Abstract
The present invention relates to a phosphate-based acrylate crosslinking agent for polymer electrolyte and a polymer electrolyte composition comprising the phosphate-based acrylate crosslinking agent, and in particular to a phosphate-based acrylate crosslinking agent where a phosphate-based compound is introduced with a polyalkylene oxide group and an acrylate group and a polymer electrolyte composition comprising the phosphate-based acrylate crosslinking agent. The polymer electrolyte composition can be applied to electrolyte thin film and polymer electrolyte of small and large capacity lithium-polymer secondary battery due to its superior ionic conductivity and electrochemical and thermal stability, where the physical properties of electrolyte composition may be controlled by means of the length of polyalkylene oxide of the crosslinking agent.
