摘要： 利用化学模式识别方法对不同合成工艺条件制备的锰酸锂材料的放电容量和循环寿命进行了分析, 得出了提高锰酸锂材料相应性能的判据. 在锰酸锂材料的放电容量和循环寿命影响因素中, 锂锰比是最主要的影响因素, 添加剂是次要影响因素,合成温度、合成时间对性能影响很小.

关键词: 锰酸锂, 放电容量, 循环寿命, 化学模式识别

Abstract: The discharge capacity and the cycle lifetime of Li-Mn-O spinel oxide with different technology factors were analyzed by chemical pattern recognition method, and some criteria for improving material properties were obtained. The ratio of lithium to manganese was the primary influencing factor on discharge capacities and cycle lifetime for Li-Mn-O spinel oxide. Additive was the secondary influencing factor. Synthesis temperature and time
impacted the properties slightly.

Key words: Li-Mn-O spinel oxide, Discharge capacity, Cycle life time, Chemical pattern recognition
