Our recent works about nanosized materials for lithium ion batteries are reported, including the synthesis of nanosized Sb, SnSb, CuSn x, Si and CuS, their electrochemical performance as anode or cathode active materials,the variation of crystal structure and morphology during discharge and charge cycling. In addition,the self_plasticization of lithium salt with nanosized anion ion in polymer electrolyte,the influence of the electrochemical Li_doping on the Raman spectra and photoluminescence of nano_Si are also introduced. Furthermore,the relationship between intrinsic properties of nanosized materials and their electrochemical behaviors are discussed. The prospect of nanosized materials for lithium ion batteries is drawn.

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.
