A silver-oxide battery is a primary, non-rechargeable cell that uses silver oxide as its cathode material and zinc for its anode, and it holds a nearly constant nominal voltage throughout discharge until the cell is fully depleted, a property that makes it attractive for devices needing steady voltage over their whole working life. Silver-oxide batteries are most commonly sold in the small button-cell format, where only a minimal amount of silver is required, keeping the silver content from becoming a prohibitively expensive part of the finished product cost; in Japan, silver-oxide primary batteries accounted for roughly 30 percent of all primary battery sales in February 2020, 64 million cells out of 212 million sold that month.
