Electronic structure formed by Y2O3-doping in lithium position assists improvement of charging-voltage for high-nickel cathodes - Nature Communications

AbstractHigh-capacity power battery can be attained through the elevation of the cut-off voltage for LiNi0.83Co0.12Mn0.05O2 high-nickel material. Nevertheless, unstable lattice oxygen would be released during the lithium deep extraction. To solve the above issues, the electronic structure is reconstructed by substituting Li+ ions with Y3+ ions. The dopant within the Li layer could transfer electrons to the adjacent lattice oxygen.
