Abstract
Disclosed herein are a lithium air battery having a multi-layered electrolyte membrane and a method of manufacturing the same. The lithium air battery includes a first electrolyte membrane capable of obtaining high ionic conductivity on a lithium negative electrode surface while minimizing the content of polymer and positioning a second electrolyte membrane with high resistance to oxygen radicals on the air electrode. Accordingly, the multi-layered electrolyte membrane can improve an electrolyte filling characteristic and a conductive characteristic of lithium ions, suppress oxygen radicals from being carried from an air electrode, and suppress a growth of lithium dendrite to largely improve a battery lifespan.
