Abstract
Abstract Research on high‐entropy ceramics (HEC) is rapidly expanding; the myriad of unexplored compositions creates unique opportunities. Compared to the state of the art materials, HECs have shown favorable improvement on the long‐term stability and durability of secondary batteries (i.e., Li, Na, K, and S). This short review summarizes the recent (2015‐2020) progress done in the field of HECs for reversible energy storage (26 peer reviewed papers); it gives an overview on materials chemistry, reactivity/synthesis, processing routes, electrochemical performance, and applications. It also surveys 18 patents to trace the growing technological interest. The charge and discharge performance are analyzed and compared with reference established materials.
