正极材料是目前锂离子电池中锂离子的唯一或主要提供者,也是锂离子电池能量密度提高和价格降低的瓶颈。本文在简要介绍几类典型的正极材料结构、性能特点及存在的主要问题后,重点介绍本实验室近年来在正极材料的表面改性和结构设计方面的研究进展。
The cathode (positive electrode) is the single (or major) donor of lithium ions in current lithium ion batteries. It is becoming the bottleneck to the increase of energy density and the decrease of cost of lithium ion batteries. This review presents the research progress in our laboratory in surface modification and structural designing of cathode materials after a brief introduction to the structures, the performance features and the main problems of some typical cathode materials.
