摘要
以熔融法合成了锂二次电池正极材料Ｌｉ１＋ ｘＶ３Ｏ８ ，并考查了热处理温度和时间对其首次放电容量的影响。通过Ｘ 射线衍射以及阻抗谱等手段分析了热处理影响材料性能的原因。
Cathode material——Li 1+ x V 3O 8 for secondary lithium ion batteries was synthesized using a smelt process, and the influences of heat treatment temperature and time on its 1st discharge capacity were investigated. The authors analyzed the reason why the heat treatment affect the performances of the material by means of XRD and impedance spectroscopy.
