The difference of reactive mechanisminduced the difference of their structure . v _ 2o _ 5 product prepared by melting - cooling showed more notable undefined structure . after heat - treating under300 , particle size becomes smaller , and aggregate to globate grain , showesbetter electrochemical performance at low charge - discharge rate 熔融淬冷法合成的样品其无定型结构更明显，前驱体经过300热处理后，材料的粒径变细，团聚成球状的颗粒，球状特征更显著，在低倍率下具有较好的电化学性能。
