High-Energy Manganese-Rich Rocksalt Cathodes with Engineered Oxygen Vacancies

Key Points

The research aims to investigate the structural transformation of manganese-rich rocksalt cathodes and its implications for energy density.
Characterization of manganese-rich disordered rocksalt (DRX) cathodes
Assessment of structural changes upon cycling
Evaluation of energy density and cycling stability
Manganese-rich DRX cathodes showed transformation to a spinel-like δ-phase upon cycling
This transformation led to increased energy density
Improved cycling stability was observed with engineered oxygen vacancies

Abstract

Manganese-rich (Mn > 0.6) disordered rocksalt (DRX) cathodes undergo structural transformation into a spinel-like δ-phase upon cycling, resulting in enhanced energy density and cycling stability. This transformation is a gradual...
