High energy density and micrometer-sized d0-free disordered rocksalt cathodes

Key Points

• Improved cycling performance was observed in disordered rocksalt cathodes, enhancing battery efficiency.
• Key evidence reveals that these new cathodes are free of critical metals, which reduces manufacturing costs.
• Assessment involved synthesizing new materials with high energy density and evaluating their stability during cycles.
• Findings emphasize the potential of low-cost alternatives to support growing energy storage demands.
