Abstract
The formation of microcracks in agglomerated particles of positive electrode (cathode) material based on Ni-enriched layered oxide LiNi0.6Mn0.2Co0.2O2 has been studied using transmission electron microscopy. The influence of magnesium cations as a doping additive on the stability of the material to the accumulation of structural defects and the formation of cracks during long-term galvanostatic cycling is demonstrated, and a mechanism for stress relaxation is proposed.
