Due to its high energy density, lithium-air battery has been one of the research hotspots. However, there are still many issues that need to be addressed, especially when working in an open environment. In this paper, the pouch-type non-rechargeable lithium-air batteries were fabricated by using high loading air electrode and waterproof and breathable PDMS film, and their discharge performance in an open environment was studied. Due to the high waterproof and breathable performance of PDMS, the battery has better discharge and storage performance. The discharge time is more than
