摘要
为提高锂离子蓄电池正极材料LiFePO4的充放电性能,用V对LiFePO4进行掺杂。研究了V掺杂量对LiFePO4性能的影响,在LiVxFe1!xPO4(x=0.00,0.01,0.03,0.05,0.10)材料中,LiV0.05Fe0.95PO4具有比LiFePO4更好的电化学性能,用80mA/g的电流进行充放电时,首次放电容量为130.429mAh/g,循环20次后为131.196mAh/g。
In this paper, vanadium was doped into LiFePO4 to improve its performance .The effect of V content on the characteristic of LiFePO4 was studied. LiV0.05Fe0.95PO4 showed more higher capacity than LiFePO4 through the research on LiVxFe1-xPO4 （x=0.00, 0.01, 0.03, 0.05, 0.10）. The 1 st discharge capacity of 130.429 mAh/g and the 20 th capacity of 131.196 mAh/g can be obtained at 80 mA/g charge-discharge rate.
