This battery showed good results in heavy load discharge and discharge at low temperature compared to those of Examples 1 and 2. This is probably because silver oxide is added to the electrode in the layer close to the cathode, and is released from the silver oxide.
- the part where the AgO surface and the plastic sheet are in contact is not reduced because the reduction of the AgO surface has not progressed compared to other parts.
- Ag 20 and And / or the reduced layer of Ag was not substantially formed. This is because it is difficult for the electrolyte to enter the area
