Carbon-coated Ni_0.5Mg_0.5Fe_1.7Mn_0.3O₄ nanoparticles as a novel anode material for high energy density lithium-ion batteries

Abstract

The Ni0.5Mg0.5Fe1.7Mn0.3O4/C composite electrode demonstrates a higher capacity (>800 mAh g−1), surpassing graphite and other spinel anodes. With an energy density of 360 Wh kg−1, it shows promising potential for enhancing the electrochemical performance of Li-ion batteries.
