  • Lithium secondary battery
    Patent number: 6503661
    Abstract: A composition for forming polymer electrolyte and a lithium secondary battery employing the polymer electrolyte prepared using the composition are provided. The composition for forming polymer solid electrolyte having a polymer resin, a plasticizer, a filler and a solvent, wherein the filler is synthetic zeolite having an affinity for an organic solvent or moisture. Therefore, the mechanical strength and ionic conductivity can be improved by adding synthetic zeolite as a filler when forming polymer electrolyte. Also, use of such polymer electrolyte makes it possible to prepare lithium secondary batteries having good high-current discharge characteristics and excellent discharge capacity characteristics even under repeated charge/discharge conditions.
