  • Patent number: 6783897
    Abstract: The present invention relates to a crosslinking agent comprising methyl siloxane polymer of a backbone having a polyalkylene oxide group as a branch group and acryl groups at both ends, and a crosslinkable solid polymer electrolyte composition comprising a crosslinking agent, a lithium salt, an organic solvent, and a curing initiator mixed in a certain ratio. The crosslinkable solid polymer electrolyte composition has a high ionic conductivity at room temperature and can be readily formed into a film and is thus suitable for use in large-size lithium-polymer secondary batteries applicable to electric cars, power storage devices for power leveling and the like, as well as in small-size lithium-polymer secondary batteries applicable to video cameras, portable data terminals such as cellular phones and notebook computers, and the like.
