Water-Stable Lithium Electrode and Its Application in Aqueous Lithium/Air Secondary Batteries

Abstract

A water-stable lithium electrode (WSLE) consisting of a lithium sheet as active layer, a nanocomposite polymer membrane as buffer layer, and lithium-ion conducting glass ceramics as water-stable protective layer, was fabricated as the anode for aqueous lithium-air secondary batteries. The WSLE with the polymer electrolyte containing BaTiO₃ nano-filler (average particle size 40 nm) showed a total electrode resistance of 118 Ω cm² in the WSLE/1 M LiCl/Pt black, air cell at 60°C, and exhibited a good cyclic performance for the dissolution and deposition of the lithium ions.
