Lithium metal batteries hold immense potential for high-energy applications, yet they face significant challenges such as lithium dendrite, dead lithium formation, and volume expansion. Herein, an innovative strategy is proposed to address these issues. Specifically, a high-entropy alloy (HEA) composed of Mg, Ag, Cu, Mn, and Ni is synthesized on graphitized carbon paper via a simple impregnation and high-temperature thermal reduction method, serving as the anode for lithium metal batteries.
