This paper presents a Review on the development of thin‐film (all‐solid‐state) Li‐ion microbatteries. The need to move from 2D to 3D configurations, the ever‐increasing necessity to adopt Li‐ion or rocking‐chair technology in microbatteries, and the development of new processing techniques and materials are discussed. Materials based on TiO2 are very promising as negative electrodes for Li‐ion microbatteries. Strong emphasis is placed on the possibility of utilising TiO2, especially self‐supported nanotubular TiO2, as an anode material for commercial 2D or 3D Li‐ion microbatteries. The use of TiO2 is ecologically and economically competitive and provides cells with low self‐discharge while eliminating the risk of overcharging due to its relatively high operating voltage. The high operating voltage of TiO2 also presents the advantage of negligible electrolyte decomposition. Each polymorphic form of TiO2 (anatase, rutile, TiO2(B), or brookite) has an attractive lithium storage behaviour, especially, when nanostructured. Owing to their remarkable nanoarchitecture, TiO2 nanotubes grown by potentiostatic anodization, and their derivatives (cation‐ or anion‐doped and hierarchical composites with nanostructured metals or metal oxides), deserve attention for the fabrication of 2D or 3D Li‐ion microbatteries.

“…As a function of the anodization conditions, diameters may vary between 30 and 200nm while lengths can be adjusted between 200nm and 1000 μm when working in non-aqueous electrolytes (27,28). More recently, it was shown that self-assembled titania nanotubes can be used as seed layers for the fabrication of vertical tin nanowires (29)(30)(31). The fact that self-assembled TiO 2 nanotube arrays can be prepared on Si wafers (32)(33)(34) constitutes another important asset of these materials opening the path towards on-chip integration of many of the applications mentioned above.…”

Electrolyte contacts were used to investigate the properties of pure and N-doped titania nanotubes (ntTiO 2 ). Mott-Schottky analysis gave a flat-band potential E fb = -0.57V vs. Ag/AgCl for pure ntTiO 2 and E fb = -0.22V vs. Ag/AgCl for N-doped ntTiO 2 . The charge carrier density was N D = 6.7 10 20 cm -3 for pure ntTiO 2 and N D = 3.9 10 20 for N-doped ntTiO 2 . This investigation also allowed estimation of the apparent diffusion coefficient of H + in ntTiO 2 . Following the Randles-Sevcik method, the effective proton diffusion coefficient in ntTiO 2 is (2±1)·10 -11 cm 2 s -1 while in Ndoped ntTiO 2 it is (4±1)·10 -11 cm 2 s -1 . Using the Warburg diffusion element determined by electrochemical impedance spectroscopy, the proton diffusion coefficient is (2±1)·10 -11 cm 2 s -1 for pure ntTiO 2 while for nitrogen-doped ntTiO 2 a value of (7±3)·10 -11 cm 2 s -1 is found. These values are consistent with those of the RandlesSevcik method.
