锂离子电池锑基负极材料的研究现状

Research status quo of Sb-based anode materials for Li-ion battery

锑(Sb)基材料用作锂离子电池负极,存在合金化/去合金化过程的体积膨胀问题,阻碍商业化应用。总结金属锑、锑基合金及锑基化合物材料(如锑基氧化物、锑基硒化物和锑基硫化物等)作为锂离子电池负极材料时存在的体积膨胀等问题,归纳相应的解决策略,如材料纳米化、碳包覆等;分析不同改性手段制备材料性能提升的主要原因。对锑基负极材料在未来新能源材料领域的应用方向进行展望。

Antimony(Sb)-based materials were used as anodes for Li-ion battery,there was a problem of volume expansion during the alloying/dealloying process,which hindered its commercial application.The problems such as volume expansion when metal antimony,antimony-based alloys and antimony-based compounds(such as antimony-based oxides,antimony-based selenides and antimony-based sulfides)as anode for Li-ion battery were summarized,the corresponding solutions were concluded,such as material nanocrystallization,carbon coating and so on.The main reasons for the performance improvement of materials prepared by different modification methods were analyzed.The application direction of antimony-based anode materials in the field of new energy materials in the future was prospected.
