Zn-air Battery

Considering global warming and the growing energy demand in modern society have motivated the researchers to develop better energy conversion and storage systems. Zinc is one of the most widely used electrodes and has various advantages, such as environmentally friendly, earth abundant, low cost, easy to handle, stable in aqueous solution. In the zinc air battery, zinc and oxygen from the air work together to generate a steady level of power, which makes it the ideal battery for new generation digital hearing aids. It consists of a porous air cathode and a Zn metal anode, separated using a membrane separator and filled with a concentrated alkaline electrolyte. Zinc-air secondary batteries can be classified into two categories: electrically rechargeable and mechanically rechargeable systems. EESC lab doing research on rechargeable zinc-air battery components with different aspects.
