锂离子电池正极材料掺杂和表面包覆研究综述

Review of doping and surface coating of cathode materials for lithium ion batteries

随着国家政策对电动汽车的支持力度不断加大,锂离子电池的电化学性能瓶颈愈发凸显.本文综述了锂离子电池正极材料钻酸锂、猛酸锂、磷酸铁锂及三元材料在掺杂和表面包覆两种工艺对电池电化学方面的影响,并展望了掺杂和表面包覆两种工艺未来的研究方向.

With the increasing support of the national policy on the electric vehicle,the bottleneck of the electrochemical performance of the Li-ion battery is becoming more and more prominent.The safety of the lithium-ion battery has not been resolved since the material's chemical performance is limited.The effects of lithium,lithium,lithium iron phosphate and ternary materials on the electrochemical performance of lithium-ion battery positive electrode material,lithium,lithium manganate,lithium iron phosphate and ternary material on the electrochemical properties of the battery were summarized.
