Decreasing Li/Ni Disorder and Improving the Electrochemical Performances of Ni-Rich LiNi_0.8Co_0.1Mn_0.1O₂ by Ca Doping

Decreasing Li/Ni disorder has been a challenging problem for layered oxide materials, where disorder seriously restricts their electrochemical performances for lithium-ion batteries (LIBs). Element doping is a great strategy that has been widely used to stabilize the structure of the cathode material of an LIB and improve its electrochemical performance. On the basis of the results of previous studies, we hypothesized that the element of Ca,...
