What is Decreasing Li/Ni Disorder and Improving the Electrochemical Performances of Ni-Rich LiNi~0.8~Co~0.1~Mn~0.1~O~2~ by Ca Doping about?
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, which has a lower valence state and larger radius compared to Ni 2+ , would be an ideal doping element to decrease the Li/Ni disorder of LiMO 2 materials and enhance their electrochemical performances. A Ni-rich LiNi 0.8 Mn 0.1 Co 0.1 O 2 cathode material was selected as the bare material, which usually shows severe Li/Ni disorder and serious capacity attenuation at a high cutoff voltage. So, a series of Ca-doped LiNi 0.8(1-x) Co 0.1 Mn 0.1 Ca 0.8x O 2 (x = 0-8%) samples were synthesized by a traditional solid-state method. As hypothesized, neutron diffraction showed that Ca-doped LiNi 0.8 Co 0.1 Mn 0.1 O 2 possessed a lower degree of Li/Ni disorder, and potentiostatic intermittent titration results showed a faster diffusion coefficient of Li +
