Potassium ion batteries (PIBs) are regarded as one of promising low-cost energy storage technologies. Achieving long cycle life and high energy density has been considered as important tasks for developing high-performance PIBs. The alloy-based anodes for PIBs have attracted great attentions because of their high theoretical capacity and relatively low operating voltage. In this review, the latest advance in the related alloy-based anodes was overviewed. Specifically, the correlations among the morphology and potassium storage performance, phase transition mechanisms, the formation of solid electrolyte interphases and ionic transport kinetics are critically discussed. It is expected that this review will provide meaningful guidance and possible pathways for the developments of alloy-based anodes for PIBs. In this review, the latest advance in the related alloy-based anodes was overviewed.
