Boosting Fast-Charging Performance of Ni-Rich NCM9055 Cathodes with Nb<sub>2</sub>O<sub>5</sub> Dual Functional Modification. [PDF]
Adv Sci (Weinh)A dual‐functional Nb2O5 modulation strategy is reported to overcome kinetic limitations in Ni‐rich cathodes. The formation of LiNbO3 phase at the grain boundary of the polycrystalline NCM9055 cathode preserves a radially aligned microstructure and establishes fast lithium‐ion pathways.
