A composite polymer electrolyte was prepared by in situ cross-linking between vinyl-functionalized SiO2 particles on the PAN membrane and the electrolyte precursor containing tri(ethylene glycol) diacrylate. The cross-linked composite polymer electrolyte effectively encapsulated the electrolyte solution without leakage. It exhibited good thermal stability as well as favorable interfacial characteristics toward electrodes. Lithium-ion polymer cells composed of a graphite negative electrode and a LiNi(0.)8Co(0.15)Al(0.0)5O(2) positive electrode were assembled with the in situ cross-linked composite polymer electrolyte. The cells with cross-linked composite polymer electrolytes using the fibrous PAN membrane and vinyl-functionalized SiO2 particles exhibited high discharge capacity and good capacity retention at both ambient temperature and elevated temperature.
