Origin of structural degradation in Li-rich layered oxide cathode

Tongchao Liu et al.

Summary: Utilizing Li- and Mn-rich (LMR) cathode materials can increase battery energy density. However, voltage decay issues impede commercialization. In this study, it is revealed that nanostrain and lattice displacement accumulate continuously during operation, leading to structure degradation and oxygen loss, which cause rapid voltage decay. The heterogeneous nature of LMR cathodes results in pernicious phase displacement/strain. Mesostructural design is proposed as a strategy to mitigate lattice displacement and achieve stable voltage and capacity profiles.
