High Entropy Fine‐Tuning Achieves Fast Li+ Kinetics in High‐Performance Co‐Free High‐Ni Layered Cathodes

at 0.2 C and a full cell with a high capacity retention of 83.1% after 1500 cycles at 3C. This work provides a promising avenue for commercializing Co-free high-Ni cathodes for next-generation LIBs.
