High-capacity power battery can be attained through the elevation of cut-off voltage for LiNi0.83Co0.12Mn0.05O2 high-nickel material. Nevertheless, unstable lattice oxygen would released during lithium deep extraction. To solve above issues, electronic structure is reconstructed by substituting Li+ ions with Y3+ ions. The dopant within Li layer could transfer electrons to adjacent oxygen. Subsequently, accumulated in site are transferred nickel highly valence state under action reduction coupling mechanism. modified strategy suppresses generation defects regulating local structure, but more importantly, it reduces concentration reactive Ni4+ species charging state, thus avoiding evolution an unexpected phase transition. Strengthening strength between layers and transition metal finally realizes fast-charging performance improvement cycling stability enhancement high voltage. Authors report on restructuring a material This mechanism improving high-voltage stability.
