| 摘 要： | 1 Introduction With the development of portable electric devices,polymer lithium ion batteries (PLiBs) have been widely used as the power sources because of their high energy density and safe property[1].P(AN-MMA) copolymer is a kind of cheap macromolecules easily dissolving in the polar solvents such as carbonate,it has been applied as gel polymer electrolyte in PLiBs.Here we prepare a kind of highly conductive nano-composite polymer electrolytes using the P(AN-MMA) copolymer incorporated with TiO2 nanoparticles as polymer matrix.The nano-composite polymer materials are prepared by an in-situ polymerization method.Nano-composite polymer electrolytes (NCPEs) are prepared by immersing the obtained porous P(AN-MMA)/TiO2 nano-composite polymer membranes in non-aqueous electrolyte.Their electrochemical characteristics were discussed here.
