摘要
尖晶石型锰酸锂具有独特的三维锂离子扩散通道,作为锂离子电池正极材料具有良好的充放电循环性能,且具有原材料价格便宜,对环境无污染等优点,使其成为最有希望替代LiCoO2的正极材料。尖晶石型LiMn2O4的制备方法成为近年来研究的重点,其中溶胶-凝胶法具有突出的优越性。简述了溶胶-凝胶法的基本原理,综述了溶胶-凝胶法在锰酸锂的制备及改性上的研究进展。
Spinel lithium manganate is the most promising anode for lithium-ion batteries as a substitute for Li- CoO2, because of it＇s unique three-dimensional lithium ion diffusion channels. It had excellent charge-discharge cycle performance,low material cost and environmental harmlessness. The methods for preparing spinel LiMn2O4 became the focus of research in recent years and sol-gel method had outstanding advantages. The basic principles of the sol-gel method was outlined. The research progress on preparation and modification of LiMn2O4 by sol-gel method was summarized.
