An all‐solid‐state silver battery made from a single material is reported. NASICON‐type Ag_1.5Cr_0.5Ti_1.5(PO₄)₃ functioned as the anode, cathode, and electrolyte. High rate capability at 298 K and low temperature operation (233 K) were possible due to its high electrical conductivity and low interfacial resistance with the concept of a single‐phase battery. The redox reactions of Ag/Ag⁺ (anode) and Cr³⁺/Cr⁴⁺ (cathode) were confirmed from X‐ray diffraction and X‐ray photoelectron spectroscopy measurements. The operating voltage of the battery in this study was higher than that for a silver battery using an AgI solid electrolyte because of the high redox potential of the cathode and the wider potential window of Ag_1.5Cr_0.5Ti_1.5(PO₄)₃ than that of AgI. Therefore, Ag_1.5Cr_0.5Ti_1.5(PO₄)₃‐based single‐phase battery is a promising new concept to obtain a high voltage silver‐ion battery, high‐rate capability and low temperature operation.
