Metal phosphides are regarded as promising anode candidates for high‐energy‐density potassium‐ion batteries (PIBs) due to their high theoretical capacity and relatively low operation voltage. The failure mechanism of the metal phosphides originates from the large volume variation during cycling, which leads to fast capacity degradation. Herein, concentrated electrolyte is used to achieve impressive cycling stability for K‐metal and K‐ion batteries over their more dilute counterparts, mainly…
