摘要
综述了锰酸锂(LiMnO2)正极材料的研究现状。该材料属于亚稳态结构,通常采用软化学方法合成,如溶胶-凝胶技术、水热反应和离子置换等。由于Mn元素多价态的特点,LiMnO2有很多种微观结构。LiMnO2的循环性能具有一个基本的特点,即初期容量较低,存在活化过程,循环若干次后,放电容量变得稳定。
Research status quo of cathode material lithium manganese oxide （LiMnO2） was summarized. The material was meta- stable phase structure, generally synthesized by soft chemical techniques, such as sol-gel technique, hydrothermal reaction and ion exchange. Due to polyvalent states of Mn element, LiMnO2 had many microstructures. The cycle performance of LiMnO2 had a ba-sic characteristic of low initial capacity. It had activation process, after several cycles, the discharge capacity became stable.
