The all-solid-state Li-air battery has been fabricated, which is constructed by a lithium foil anode, NASICON-type solid state electrolyte Li1+xAlyGe2-y(PO4)3 (LAGP) and single-walled carbon nanotubes (SWCNTs)/LAGP nanoparticles composite as air electrode. Its electrochemical performance was investigated in atmosphere. Particularly, this exhibited larger capacity about 2800 mAh g(-1) for the first cycle, while comparatively with multiwalled (MWCNTs)/LAGP cathode had of only 1700 g(-1). Also, SWCNTs/LAGP showed improved cycling reversible 1000 at current density 200 mA Our result demonstrated that catalyst considerable potential practical application.
