Optimization of zinc electrodeposition from zinc-air cell discharge performance

Porous zinc electrodes were prepared from an acidic, chloride electrolytic bath for application in zinc-air microbattery. The aim is to produce a high specific surface area zinc coating in order to obtain high storage capacity and high limiting current density of the microbattery. The electrolytic b...
