Abstract: A number of polymer materials as candidates of host matrix of plastic polymer electrolyte were examined and techniques for preparation of thin_film electrolyte were reported. The results showed that the polymer electrolyte prepared with P(VDF_HFP) copolymer as host matrix and DBP as plasticizer exhibit the satisfactory mechanical strength and ionic conductivity. In comprison with liquid electrolyte systems, thin_film lithium ion battery has almost similar charge_discharge capacity and cycleability. The manufacture methods and the technical factors in making plasticizing lithium ion battery were also described in details.

Key words: Polymer electrolyte, Lithium ion battery, Plasticizing
