A new spinel high-entropy oxide (Mg0.2Ti0.2Zn0.2Cu0.2Fe0.2)3O4 with fast reaction kinetics and excellent stability as an anode material for lithium ion batteries

Here we present novel (Mg_0.2Ti_0.2Zn_0.2Cu_0.2Fe_0.2)₃O₄ materials prepared via one-step solid state reaction method and subsequently high-energy ball-milling. When used as anodes for LIBs, it exhibits superior lithium storage properties.
