A Comparison of as-synthesized P2-K0.70[Cr0.85Sb0.15]O2 and Ion-Exchanged P2-K0.62Na0.08[Cr0.85Sb0.15]O2 Demonstrates the Superiority of the Latter as a Potassium-Ion Battery Cathode

In this study, P2-type K0.7[Cr0.85Sb0.15]O2 (KCSO) is prepared via a solid-state route and its electrochemical properties are compared with those of P2-K0.62Na0.08[Cr0.85Sb0.15]O2 (IE-KCSO), which is prepared via an electrochemical ion-exchange of P2-Na0.7[Cr0.85Sb0.15]O2. Despite the near-identical...
