Ti‐Based Surface Integrated Layer and Bulk Doping for Stable Voltage and Long Life of Li‐Rich Layered Cathodes

High‐energy‐density lithium‐rich layered oxides (LLOs) hold the greatest promise to address the range anxiety of electric vehicles. Their application, however, has been prevented by fast voltage decay and capacity fading for years, which mainly originate from irreversible transition‐metal migration...
