We report the fabrication of an all-solid-state lithium-ion battery composed of self-supported titania nanotubes (TiO(2)nts) as anode, a thin film of polyethylene oxide (PEO) carrying bis(trifluoromethanesulfone)imide (LiTFSI) as electrolyte and a layer of LiNi0.5Mn1.5O4 as cathode. The battery shows an operating voltage of 2.1 V and delivers a stable discharge capacity of 80 mA h g(-1) (30 mu A h cm(-2) mu m(-1)) at a kinetic rate of C/10 with a capacity retention of 91.5% and a coulombic efficiency of 96.7%. This full cell showing high performance is compatible with the integrated circuit technology.
