Misfit strain-induced mechanical cracking aggravating surface degradation of LiCoO2

open access: yesMaterials Research Letters, 2023
Cycling-induced cathode interfacial degradations are usually attributed to chemical process, while the physical effect is overlooked to a large extent. Herein, we investigate the failure mechanism of LiCoO2 cathode and reveal that misfit strain plays a ...
