The Cover Feature illustrates a structural schematic of the flexible full K‐ion battery using a superconcentrated water‐in‐salt hydrogel electrolyte. Such a high‐voltage and high‐safety battery assembled using a KMnFe(CN) 6 cathode and a KTi 2 (PO4) 3 /C anode shows significant potential for wearable and flexible electronic devices.
