Regulating Surface Chemistry and Interfacial Kinetics of Ni-Rich NCM Cathodes via a Polyaniline-Derived Interphase.

Ni-rich LiNixCoyMn1-x-yO2 cathodes (NCM, Ni ≥ 80%) are promising for high-energy lithium-ion batteries, but their practical use is constrained by surface instability, interfacial side reactions, and sluggish charge-transfer kinetics during cycling. Herein, a conductive interphase derived from polyaniline (PANI) was con...
