ABSTRACT: In this study, pure and Mg2+/Cr3+ co-doped Ni/Mn bimetallic oxides were used as precursors to synthesize pristine and doped LNMO samples. The LNMO samples exhibited the same crystal structure as the precursors. XRD analysis confirmed the successful synthesis of LNMO cathode materials using Ni/Mn bimetallic oxides as precursors. FTIR and Raman spectroscopy reveal that Mg2+/Cr3+ co-doping promotes the formation of the Fd3m disordered phase, effectively reducing electrochemical polarization and charge transfer resistance. Furthermore, co-doping significantly lowers the Mn3+ content on the LNMO surface, thereby mitigating Mn3+ dissolution. Significantly, Mg2+/Cr3+ co-doping induces the emergence of high-sur
