Abstract

The unconventional ionic solid, K6[Rh4Zn4(L‐cys)12O]·nH2O, exhibited excellent formability as well as high ionic conductivity. These features enabled a straightforward assembly of all‐solid‐state potassium‐ion battery: A cold‐pressed solid sample of K6[Rh4Zn4(L‐cys)12O]·nH2O, which was sandwiched by solid samples of K2Ni[Fe(CN)6] and chloranil as cathode, and anode, respectively, displayed an initial discharge capacity of 21.6 mAh g−1‐electrodes at 25 °C at a current density of 0.5 mA cm−2 (∼0.34C). Energy dispersive X‐ray spectroscopy analysis confirmed that K+ ions swiftly conduct through K6[Rh4Zn4(L‐cys)12O]·nH2O between the cathode and anode during charge–discharge cycles.
