摘　　要：介绍了V2O5的发展概况;论述了溶胶-凝胶法合成非晶态V2O5的研究进展;指出了V2O5作为锂金属聚合物(LMP)电池正极时,存在的大电流放电性能差、容量低、循环寿命短等问题,分析了原因,并给出了解决办法,如V2O5掺杂Ag、Cu、聚吡咯和聚噻吩改性等。The developing survey of V2O5 was introduced. Research progress in the preparation of amorphous V2O5 by sol-gel method was discussed. Problems of V2O5 as lithium metal polymer （LMP） battery cathode were pointed out, the causes were analyzed and solutions such as doping Ag, Cu, poly pyrrole and poly thiophene into V2O5 for modification were given.
