Silver(I,III) oxide is a chemical compound used as part of the manufacture of silver oxide-zinc alkaline batteries. It has an empirical formula AgO, which might suggest that silver is in the +2 oxidation state. However, evidence such as the observed diamagnetism of the compound and X-ray diffraction studies show that it is better formulated as AgIAgIIIO2.[1] It is also known as silver peroxide, although it does not have peroxide (O22−) anions.
