Recent Developments in Alloying‐type Anode Materials for Potassium‐Ion Batteries.

As an energy‐storage system, rechargeable potassium‐ion batteries (PIBs) have aroused widespread attention in recent years due to their earth abundance, low standard redox potential, and high ionic conductivity. The development of high‐performance electrode materials is key to optimize the battery performance and useful to improve the feasibility of PIB technology. In this sense, a minireview on alloying‐type anode materials for advanced PIBs is provided, covering the potassium storage properties, reaction mechanisms, theoretical analysis, electrochemical performance, and suitable binders and electrolytes.
