Abstract
Disclosed herein is a cylindrical zinc-air cell and fabricating method thereof. The zinc-air cell comprises a film including an air anode membrane and a separator, the film being formed in a substantially cylindrical bent shape; and a junction element adapted to receive both ends of the film therein. The junction element is at least partly deformed to pressurize the both ends of the film so as to be joined to the film. By doing so, leakage of the zinc gel can be easily prevented in the fabrication of the cylindrical zinc-air cell, thereby extending the application area of the zinc-air cell.
