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