Fe Substitution Stabilizes Oxygen Redox in Li-Rich Disordered Rocksalt Cathodes
ICYS Research Fellow Dr. Chia-Ching LIN
【Key Points of This Research】
We found that Fe substitution can improve the reversibility of oxygen redox in Li-rich disordered rocksalt cathodes by modifying the local cation environment and electronic structure, while also suppressing structural degradation. This work provides new insight into how cation disorder and transition-metal chemistry can be controlled to stabilize anionic redox reactions, offering a promising materials-design strategy for developing high-capacity, Co/Ni-free cathodes for next-generation lithium-ion batteries.
