We report the improved kinetic mechanism of a nickel-rich LiNi0.84Mn0.10Co0.03Al0.03O2 cathode. The important role Co/Al in inhibiting cation disorder to increase lithium ion diffusion rate is revealed. Impressively, it retains an excellent capacity retention 76.8% after 200 cycles under high-rate condition (5C).
