Abstract

Abstract: Electrochemical performances of Mn-series power batteries produced by MGL were studied, and compared with LiFePO₄ power batteries of other companies. The results indicate that the high capacity and high power batteries with spinel LiMn₂O₄ and multi metal oxides as cathode materials not only have high voltage, high energy density, good high and low temperature properties, excellent rate of charge and discharge, stable thermal performance, but also show the linear of state of charge-open-circuit voltage (SOC-OCV) relationship, and then the battery manage system (BMS) can be easily controlled. Therefore, Mn-series power batteries will be the important direction for future power batteries.

Key words: power battery, multi metal oxides, spinel LiMn₂O₄, LiFePO₄

摘要： 采用尖晶石锰酸锂和以锰为主的多元金属氧化物正极材料分别研制了Mn 系正极高功率和高容量动力锂离子二次电池, 研究并比较了Mn 系动力电池与海内外几家公司制造的LiFePO₄动力电池的电化学性能。结果表明Mn 系高容量和高功率动力电池不仅具有高能量密度、优越的高低温与倍率充放电特性、热稳定性良好, 同时电池的 SOC-OCV 线性关系还有利于管理系统的控制, 因此该类动力电池会成为今后动力电池的一个重要发展方向。
