Silver oxide batteries can be recycled to recover the mercury through the use of both Hydrometallurgical methods and pyrometallurgical methods. [14] More recent silver oxide batteries no longer contain mercury and the process of recycling them does not give cause for concern for releasing mercury into the environment. [14]
A silver oxide battery uses silver(I) oxide as the positive electrode , zinc as the negative electrode , plus an alkaline electrolyte, usually sodium hydroxide (NaOH) or potassium hydroxide (KOH). The silver is reduced at the cathode from Ag(I) to Ag, and the zinc is oxidized from Zn to Zn(II).
Silver zinc cells share most of the characteristics of the silver-oxide battery, and in addition, is able to deliver one of the highest specific energies of all presently known electrochemical power sources.
