Silver oxide battery
Battery using silver oxide as the cathode material
A silver oxide battery (IEC code: S) is a primary cell using silver oxide as the cathode material and zinc for the anode. These cells maintain a nearly constant nominal voltage during discharge until fully depleted.[2] They are available in small sizes as button cells, where the amount of silver used is minimal and not a prohibitively expensive contributor to the overall product cost.

Silver oxide primary batteries account for 30% of all primary battery sales in Japan (64 out of 212 million in February 2020).[3]
Large silver oxide batteries were used on early ICBM's and satellites because of their high energy-to-weight ratio. For example the Corona reconnaissance satellites used them, as did the Agena-D rocket upper stage.[4] Later, they were also used in the Apollo Lunar Module and lunar rover.[5][6]
