Potassium ion batteries (PIBs) are considered as promising alternatives to lithium-ion batteries due to the abundant potassium resources in earth curst. Establishing promising anode material for PIBs is an important part. Recently, rapid growing number of efforts have been devoted to developing novel anodes materials for PIBs. Alloy-based anode materials undergoing alloying reaction and featuring combined conversion and alloying reactions are attractive candidates due to their high theoretical capacities. In this review, the current understanding of mechanisms of alloy-based anode materials for PIBs are presented. The modification strategies and recent research progress of alloy-based and their composites for potassium storage is summarized and discussed. The challenges and future perspective corresponding to these materials are proposed.
