Recent developments in electrode materials for potassium-ion batteries

Author affiliations

Abstract

Due to their abundant resources and potential price advantage, potassium-ion batteries (KIBs) have recently drawn increasing attention as a promising alternative to lithium-ion batteries (LIBs) for their applications in electrochemical energy storage applications. Despite the continuous progress in identifying possible electrode materials, the development of KIBs has been challenged by different problems including low reversible capacities, unsatisfactory cycling stability, and insufficient energy density, which become serious concerns for the practical application of KIBs. In this review, we will summarize the recent advancements in both cathode and anode materials with focus on their structure–performance relationship. Meanwhile, challenges and opportunities related to the future development of KIBs are also discussed.
