dc.description.abstract应用溶胶法由CH3COOL i.2H2O、Mn(CH3COO)2和已二酸制备含锂、锰的干凝胶,经高温焙烧制得尖晶石锰酸锂L iMn2O4.XRD分析显示,该尖晶石样品的结晶度随焙烧温度而升高,容量同时增加,但如超过800℃,则循环性能变差.延长焙烧时间,容量呈先增后降趋势.优化后的焙烧条件为750℃、20 h.以此制备的L iMn2O4初始放电容量为130 mAh.g-1,经过15次循环后仍达125 mAh.g-1.zh_CN
dc.description.abstractSpinel LiMn_(2)O_(4) was prepared from CH_(3)COOLi·2H_(2)O,Mn(CH_(3)COO)_(2) and adipic acid based on sol-gel process.XRD analysis showed that when the sintering temperature increased,the crystallinity increased,and the capacity also increased.However,its cycleability reached a maximum value at 750 ℃.The sintering duration also influenced on the capacity.The optimized performance was obtained when the sintering was carried out at 750 ℃ for 20 h.Under these conditions,as-prepared spinel LiMn_(2)O_(4) presented the initial discharge capacity of 130 mAh g~(-1) and 125 mAh g~(-1) at 15~(th) cycle.zh_CN
