Boosting the electrochemical performance of the Ni-rich LiNi0.96Co0.02Mn0.02O2 cathode by high-valence Zr/Mo dual-doping.
Ni-rich oxides are attractive high-energy cathodes for lithium-ion batteries but suffer from inherent instability. Herein, we employed an ectopic Zr4+/Mo6+ dual-doping strategy to reinforce the layered structure through robust M-O bonds and the pillar effect. This strategy mitigates lattice distortion during cycling and inhibits the interface side reactions.
