Abstract
This invention provides a rechargeable cell comprising an electrode including: a plurality of porous clusters of silver particles, wherein each cluster includes: (a) a plurality of silver particles, and (b) crystalline particles of zirconium oxide (ZrO), wherein at least a portion of the crystalline particles of ZrOis located in pores formed by a surface of the plurality of silver particles. Electrodes of the present invention catalyze the reduction of oxygen in alkaline solution. When the cell is charged, the silver in the electrodes can be oxidized to AgO and further to AgO. Upon discharge, the reduction of the oxidized silver results in additional available energy. This invention provides electrodes for use in rechargeable cells or batteries and methods of making thereof.
