不同碳源包覆LiFePO4/C正极材料的制备及电化学性能
Synthesis and electrochemical performance of LiFePO4/C cathode material with different coated carbon sources
摘要
Abstract
Carbon-coated LiFePO4/C cathode material was synthesized by the solid state reaction method.Different carbon source were employed for the preparation of the LiFePO4/C material.XRD,SEM and CV tester were used for the characterizations of the LiFePO4/C material,and the effects of carbon source on the electrochemical properties of the LiFePO4/C material were studied.The results show that,compared with the LiFePO4/C material made from other carbon sources,the electrochemical performance of the LiFePO4/C material prepared from the PVC carbon source is the best,while the initial discharge specific capacity is 121.3 mAt/g; the retention rote after 5 and 100 cycles are increased to about 98.4％ and 75.2％,respectively.And,the lithium-ion battery fabricated from this LiFePO4/C cathode material exhibits good reversibility and better charging adaptive capability.关键词
