However, uncontrollable anionic redox process usually leads to structural deterioration and electrochemical degradation. Herein, a Mo\/Cl co\u2010doping strategy is proposed to regulate the relative position of energy band for modulating the anionic redox chemistry and strengthening the structural stability of Co\u2010free Li<jats:sub>1.16<\/jats:sub>Mn<jats:sub>0.56<\/jats:sub>Ni<jats:sub>0.28<\/jats:sub>O<jats:sub>2<\/jats:sub> cathodes. The incorporation of Mo with high d state orbit and Cl with low electronegativity can narrow the band energy gap between bonding and antibonding bands via increasing the filled lower\u2010Hubbard band (LHB) and decreasing the non\u2010bonding O 2p energy bands, promoting the anionic redox reversibility. In addition, strong covalent Mo\u2500O and Mn\u2500Cl bonding further increases the covalency of Mn\u2500O band to further stabilize the O<jats:sub>2<\/jats:sub><jats:sup>n\u2212<\/jats:sup> species and enhance the reversible distortion of MnO<jats:sub>6<\/jats:sub> octahedron. The strengthening electronic conductivity, together with the epitaxial structure Li<jats:sub>2<\/jats:sub>MoO<jats:sub>4<\/jats:sub> facilitates the fast Li<jats:sup>+<\/jats:sup> kinetics. As a result, the dual doping material exhibits enhanced anionic redox reversibility and suppressed oxygen release with increased cyclic stability and excellent rate performance. This strategy provides some guidance to design high\u2010energy\u2010density LLOs with desirable anionic redox reversibility and stable crystal structure via band structure engineering.<\/jats:p>","DOI":"10.1002\/smll.202401132","type":"journal-article","created":{"date-parts":[[2024,3,29]],"date-time":"2024-03-29T21:29:46Z","timestamp":1711747786000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Band Structure Engineering Promotes Anionic Redox Reversibility of Cobalt\u2010Free Li\u2010Rich Layered Oxides Cathodes"],"prefix":"10.1002","volume":"20","author":[{"given":"Xianggang","family":"Gao","sequence":"first","affiliation":[{"name":"School of Metallurgy and Environment Hunan Province Key Laboratory of Nonferrous Value\u2010Added Metallurgy Engineering Research Center of the Ministry of Education for Advanced Battery Materials Central South University  Changsha Hunan 410083 P.
