What is Insight into the Role of Co and Mn Elements in Ni-Rich LiNi~0.9~Co~ x ~Mn~0.08– x ~Al~0.02~O~2~ Cathode Materials about?

n a r y l a y e r e d o x i d e L i -Ni x Co y Mn z Al 1-x-y-z O 2 (NCMA, 1xyz ≥ 0.9) is one of the most promising cathode materials for lithium-ion batteries due to its high energy density and low cost. However, the roles of Co and Mn contents in NCMAs remain to be investigated. Herein, LiNi 0.9 Co x Mn 0.08-x Al 0.02 O 2 (x = 0.07, 0.05, 0.03) are synthesized by a hydroxide coprecipitation method and high-temperature solidphase method. The results show that Co can increase the value of the c-axis, decrease the content of Ni 2+ on the surface, and inhibit lattice expansion along the c-axis in the voltage range of 2.7-4.3 V. However, Mn has a superiority in reducing the primary particle size and preventing the sharp collapse of the lattice along the c-axis in the deep delithiated state, corresponding to a voltage range of 4.3-4.5 V. These new insights are intended to guide further research on NCMAs.
