Regulating π-Type Interactions between O 2p and TM t2g Orbitals via Ti Doping and Surface Dielectric Coatings for Li-Rich Cathode

The irreversible anionic redox reaction and oxygen release of Li-rich layered oxide cathodes seriously hinder their commercial application. Here, a synergistic modification strategy of surface dielectric coating (TiNb2O7) and bulk...
