However, though the zinc ion can diffuse through the solution, there is nowhere for the two electrons to go, so they are trapped within the electrode. This excess charge opposes further oxidation—it becomes more and more difficult to force more charge into the electrode. For this reason, zinc electrodes do basically nothing in neutral …

Zinc-silver batteries are composed of zinc metal/oxides as a negative electrode, silver/silver oxides (AgO or Ag 2 O) as a positive electrode, and potassium hydroxide (KOH) aqueous solution as an electrolyte.
Zinc-silver batteries use metal zinc as negative electrode, silver oxide (AgO, Ag 2 O or a mixture of them) as positive electrode, 22 and KOH or NaOH aqueous solution as electrolyte. The divalent oxide is relatively stable at ambient temperatures but is inclined to degrade to the monovalent state with increasing temperature and time.
