Suppressing the Impedance Rise of LiNi0.8Co0.2O2/Graphite Cells by Al, Ti and Mg Doping
rechargeable batteries doping cathode
2009/11/13
The research on utilizing lithium-ion batteries with LiNi0.8Co0.2O2-based cathode for hybrid electric vehicles is intensively underway in several national laboratories of US Department of Energy. The ...
采用草酸盐前驱体合成Ti4+、Mg2+掺杂正极材料Li(Nil/3Col/3−xMnl/3)MxO2(M=Ti, Mg)。利用XRD和SEM对其结构和形貌进行表征，并采用循环伏安、交流阻抗、恒流/恒压充放电测试其电化学性能。结果表明：Ti4+、Mg2+掺杂后晶胞体积增大，大倍率充放电时LiNil/3Col/3Mnl/3O2的电化学反应阻抗Rct降低，其大倍率充放电性能得到改善，Ti4+...
