摘要:
采用共沉淀法合成镍钴锰氢氧化物前躯体,使其和碳酸锂混合均匀后,高温焙烧合成锂离子正极材料LiNi0.5Mn0.3Co0.2O2,研究了掺杂Al(OH)3对材料循环性能的影响.用X射线衍射和扫描电镜对合成的粉末进行了表征,用电性能测试仪研究了材料的电化学性能.研究发现:温度为850 ℃时焙烧的材料具有最优的电性能,1C电流初始放电比容量达到157.2 mAh/g(2.75~4.2V),循环50次放电比容量保持率为94.8 %,循环100次材料的放电比容量保持率为90.1 %.通过少量掺杂Al(OH)3的电池材料结晶性有所提高,晶型趋于完整,但是材料的放电比容量有所降低,前100次循环掺杂对材料循环稳定性无显著改善效果.
