Abstract

Abstract: As a green method for materials synthesis, hydrothermal method has the advantage of low cost, low pollution and energy save and becomes more and more popular on synthesis of nano composite cathode materials for lithium ion batteries. In this work, high performance LiFePO₄/C nano composite material obtained by adjust the pH value, temperature and time of the hydrothermal reaction.

Key words: hydrothermal method, green chemistry, LiFePO₄

摘要： 水热法是一种低成本、低能耗、低污染的绿色化学合成方法，在锂离子蓄电池正极粉体材料的制备方面拥有广阔的前景。LiFePO₄/C复合材料因为其高安全性，有着广泛的应用，但在水热条件下不容易获得分散性好的纳米级的LiFePO₄粉体材料。本文通过研究pH值、反应温度、反应时间等影响因素对水热产物性能的影响，使用水热法制备出分散性好、电化学性能优良的LiFePO₄/C纳米复合材料。
