A new spinel high-entropy oxide (Mg_0.2Ti_0.2Zn_0.2Cu_0.2Fe_0.2)₃O₄ with fast reaction kinetics and excellent stability as an anode material for lithium ion batteries.

ABSTRACT: It is well known that transition metal oxides (TMOs) have attracted extensive attention as promising anodes for next-generation lithium ion batteries (LIBs) owing to their low cost and high theoretical capacities. However, the huge volume changes upon lithiation/delithiation cycling gradually cause drastic particle pulverization in the electrodes, thus leading to fast capacity fading and limiting their practical applications. High-entropy oxides with enhanced electronic conductivity and multiple electrochemically active elements display stepwise lithium storage behaviors, thus efficiently alleviating the volume change induced electrode pulverization problem. Herein, we report the synthesis of a new kind of spinel (Mg_0.2Ti_0.2Zn_0.2Cu_0.2Fe_0.2</
