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

Puntos clave

• 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
