Functioning Of Inorganicorganic Battery

Separators used in silver-zinc (Ag-Zn) alkaline secondary batteries are often made from regenerated cellulose. Cells using regenerated cellulose separators usually fail because the separator deteriorates through oxidation of the cellulose by soluble silver species present in the concentrated aqueous potassium hydroxide (KOH) electrolyte.
