Summary: Phosphorus composite anodes are considered promising candidates for sodium-ion batteries and potassium-ion batteries, but their practical use is limited by poor cycling stability and sluggish electrochemical reaction dynamics caused by volume variation and low electronic conductivity. Compositing with a suitable second component has been proposed as an effective strategy to potentially resolve these issues.

Summary: The current performance of Li-, Na-, or K-ion batteries is mainly limited by the specific capacity of the positive electrode. It is crucial to achieve the highest capacity possible for a given electrode material. In this study, the performance limitation of KVPO4F, a potential material for K-ion batteries, is investigated. The capacity limitation of KVPO4F is found to be related to a kinetic competition between K+ deinsertion and side reactions caused by electrolyte degradation at high potentials.
