Technical Field

Background

The zinc-silver reserve battery has the characteristics of high specific energy, high specific power, capability of discharging with large current, stable discharging voltage, high voltage precision, good reliability and safety and the like, and is widely applied to various fields. At present, the traditional pasted or powder pressed zinc electrode is adopted, and compared with the zinc electrode electrodeposited, the zinc electrode electrodeposited is an electrode with high activity, can have high specific surface and porosity, has good electrode uniformity, and is suitable for discharging under the requirements of high current density and short time, so the zinc electrode is mainly applied to bipolar zinc-silver reserve battery packs.

The bipolar zinc-silver reserve battery pack has the outstanding advantages of short activation time (which can be less than 0.5s), high specific power and the like. Since the electrode generally needs to be cut into a circular shape, the active material around the circular edge is loose, and thus the electrode generally needs to be protected by an adhesive tape. The existing adhesive tape protection bonding is manually operated, and has high requirement on operators, long operation time and low yield. The adhesive tapes of the circular electrodes of the currently known bipolar zinc-silver reserve battery pack are all in a manual operation mode; therefore, a special round electrode edge-wrapping device for the zinc-silver battery and a preparation method thereof are not available.
