Presentation Title：Modulation of crystal structures in Ni-rich ternary cathode by Nb modification

Abstract：

A comprehensive investigation explored the effects of Niobium (Nb) modification across various scales—from bulk doping to surface coating—while simultaneously optimizing the preparation process to achieve synergistic enhancements. Several key strategies were successfully implemented to create integrated bulk-surface modifications, including utilizing diverse Nb sources, such as Nb₂O₅ and NbOPO₄, employing conventional solid-state, two-step sintering process and an innovative in situ liquid-phase coprecipitation technique, which all proved particularly effective for achieving significant improvement.
