diffusion. The cathode delivers unprecedented ultrafast-charging durability, achieving 81.8% after 4000 cycles at 10 C (25 °C) and 82.0% after 1000 cycles at 3 C (60 °C). Our work demonstrates that compositionally complex doping can effectively modulate the thermodynamics of phase transformation and enhance the chemo-electro-mechanical stability of high-voltage spinel cathodes, providing new insights into the design of durable fast-charging cathode materials.
