摘要：

In this paper, a simple and feasible method of making a coin-type Li-air battery (about 20mm in diameter and 28mm in height) was proposed. A special separator having function of air breathing and moisture prevention was adopted to act as a cover to let air breathe and prevent moisture invasion as well in cathode side. At the same time, a lithium ion conductive membrane was used between a Celgard membrane and a thin lithium foil to stop oxygen infiltrate into anode side. Compared with the prior art, electrochemical performance testing results showed that the cell had both better power performance and longer service life.
