Abstract
A rechargeable aqueous lithium-air battery with a water-stable high lithium-ion conductivity and an excellent bending strength solid electrolyte as a separator between the lithium metal anode and aqueous electrolyte was developed. The cell consists of a lithium metal anode, a buffer layer of 4â¯M lithium bis(fluorosulfonyl)imide in ethylene glycol dimethyl ether, a lithium-ion conducting solid electrolyte separator of Li1.3Al0.5Nb0.2Ti1.3(PO4)3 (LANTP), a 10â¯M LiCl aqueous solution with 1.5â¯M LiOH, and an activated MnO2 air electrode. The tape-cast water-impermeable LANTP film with a small amount of epoxy resin was used as the separator between the lithium anode and aqueous electrolyte. The conductivity and 3-point bending strength of the ca 0.2â¯mm thick film was 9.1â¯Ãâ¯10â4â¯Sâ¯cmâ1 at 25â¯Â°C and 100â¯MPa, respectively. The cell with the LANTP film was operated successfully at 0.26â¯mAâ¯cmâ2 for more than 30â¯cycles at room temperature in air.
