摘　　要：综述了近年来锐钛矿TiO2、金红石TiO2、TiO2[B]及板钛矿TiO2用作锂离子电池负极材料的研究进展;比较了各种晶型的特点和嵌脱锂机理;探讨了制备方法、结构和形貌对TiO2嵌脱锂的影响;提出了TiO2库仑效率、倍率性能和循环性能不佳的原因和可能的解决方法。The research progress in anatase TiO2,rutile TiO2, TiO2[B] and brookite TiO2 used as anode material for Li-ion battery in recent years was reviewed. The features and lithium insertion/extraction mechanisms of different crystalline were eompard. The influences of preparation methods, structure and morphologies to lithium insertion/extraction of TiO2 were discussed. The reasons caused the non-ideal coulombic efficiency, rate capability and cycle performance and the possible solutions were carried out.
