SOLID ELECTROLYTE AND LITHIUM BASED BATTERY USING THE SAME

摘要

A solid electrolyte includes an interpenetrating polymer network, a plasticizer and a lithium salt. The plasticizer and the lithium salt are dispersed in the interpenetrating polymer network. The interpenetrating polymer network includes CH2-CH2-On segments, and is formed by polymerizing a first monomer R1-OCH2-CH2-OnR2 with a second monomer R3-OCH2-CH2-OmR4 under an initiator. The "R1", "R2" or "R3" respectively includes -C=C- group or -C=C- group. The "R4" includes an alkyl group or a hydrogen atom. The "m" and "n" are integers. A molecular weight of the first monomer or a molecular weight of the second monomer is greater than or equal to 100, and less than or equal to 800. The first monomer is less than or equal to 50% of the second monomer by weight. The lithium salt is less than or equal to 10% the second monomer by weight. A lithium based battery using the solid electrolyte is also provided.
