锂离子电池正极材料电化学

降低价格提高性能的推动力促使科学工作者不断开发新型锂离子电池正极材料。目前研究和使用的正极材料均具有层状结构或者是隧道式结构作为锂离子扩散和驻留的空间，这不是偶然的现象。本文简述了锂离子正极材料研究现状，在此基础上总结了正极改性和探索新型正极材料的原则。具有层状或隧道式微观结构是选择锂离子电池候选正极材料的必要前提条件。

Electrochemistry of Positive Electrode Materials of Li-ion Battery

Driving by the lower cost and better properties, the development of new positive electrode materials of Li ion battery has been paid more attention by the researchers. It is not occasional for most of positive electrode materials to have a layer type or tunnel structure. In this paper, a brief presentation on the situation of positive electrode materials was done, based on which the fundamentals to improve the positive electrode properties and to find new type materials were proposed. The necessary requirement is to have layer type structure and/or tunnel structure.
