【Abstract】 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.更多还原
