Mechanical strain phenomena in Li-ion battery cathodes are the pivotal in performance degradation and capacity fading. Two lithium-rich layered Mn-Ni-Co (MNC) cathodes were fabricated with fixed 4:1:1 transition metal cation ratio, but distinctly different microstructures. Cathodes produced based on the mixed oxide powders were incorporated in coin cells and subjected to charge cycling, following which they were extracted and extensively characterised using a multi-technique microscopy approach. The results reveal the correlation between microstructure, stress and durability and point out possible avenues for optimising cathode design to improve the stability of future generation batteries.
