Utilizing earth-abundant metals as the primary choice and combining with advantageous strategies of the multi-metal system, one could design materials for high-performance rechargeable energy storage systems. The so-called high entropy oxalates (HEOx) are an emerging class of materials in which the stabilization of a single-phase with multimetal composition leads to unique electrochemical properties and potential application as electrode material for Li-ion and Na-ion batteries. In this work, we developed high-entropy transition metal oxalates by a simple yet scalable chemical co-precipitation route. The synthesized materials were characterized for physical and chemical properties by numerous techniques, including XRD, XPS, STEM, etc., and performance evaluated as anode materials for rechargeable Li-ion and Na-ion batteries. The HEOx showed higher specific capacity, rate capability, and cyclability than binary metal oxalates and thus, offer great potential to be utilized as anode material for emerging Li-ion and Na-ion batteries.
