LITHIUM AIR BATTERY

摘要

Provided is a lithium air battery in which a catalyst layer of a cathode contacting an electrolyte and using oxygen in the air as an active material is coupled to a membrane through which lithium ions pass, such that even though charge and discharge of the battery is repeated, the catalyst layer may not be detached, and a microporous polyolefin-based film is applied to the battery, such that a water-based electrolyte solvent may be prevented from being evaporated, thereby preventing performance deterioration due to repetition of the charge and discharge of the lithium air battery, and extending life span.

主权项

1. A lithium air battery comprising:
a first electrode part including a lithium metal; a second electrode part including a gas diffusion layer of which one side contacts an air, a catalyst layer formed at the other side of the gas diffusion layer, and a membrane coupled to the catalyst layer so that lithium ions pass therethrough, and spaced apart from the first electrode part; and an electrolyte part provided between the first electrode part and the second electrode part.
