Silver electrodes were studied in 20% at 25°C and in 35% or 50% at 0°C. The capacity decreased when an electrode was cycled in 20% at 25° mainly due to loss of active material during current flow. In 35% at 0° the electrode capacity was close to that at 25°, the capacity decreased with increasing charge current similar to results at 25° although polarization had increased, and the charge‐discharge efficiency was 100% at low currents but less when using high currents. In 50% at 0° the capacity was much less than at 25°, the charge acceptance was relatively poor, under certain conditions a silver peroxy compound may form, and the electrode discharged even less readily than it charged.
