• Self-supported TiO2 nanotubes are used as a negative electrode for micropower source.
• The Li-ion battery consists of a polymer electrolyte and LiNi0.5Mn1.5O4 thin films.
• The all-solid-state battery shows a relative high electrochemical performance.
• The full cell delivers a stable capacity at different rates up to 100 cycles.
• The capacity is comparable to values reported in liquid electrolyte system.
We report the fabrication of an all-solid-state lithium-ion battery composed of self-supported titania nanotubes (TiO2nts) 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 μA h cm− 2 μm− 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.
