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.

A low cost, up-scalable and one-pot wet-mechanochemical approach is designed for fabricating TiO 2 -SnO 2 @graphene nanocomposites where TiO 2 and SnO 2 solid solution nanoparticles are evenly anchored on graphene sheets. As an anode material of lithium ion batteries (LIBs), the as-prepared nanocomposites deliver a superior rate performance of 388 mA h g À1 at 1.5 A g À1 and an outstanding reversible cycling stability (617 mA h g À1 at 0.4 A g À1 after 750 cycles, 92.2% capacity retention), due to the synergistic effects contributed from individual components, i.e., high specific capacity of SnO 2 , excellent conductivity of 3D porous graphene networks, good rate capability and structural stability of TiO 2 structures.

“…Until now, SnO 2 @TiO 2 heterostructures with good lattice and bandgap matches between rutile SnO 2 and rutile TiO 2 have been successfully prepared, and a promotion of the optoelectronic performance has also been realized. [13,14] In this report, SnO 2 @TiO 2 heterostructures were successfully grown on a carbon cloth and were directly used as a binderfree anode to assemble coin cells with the inner carbon cloth as the current collector. The hybrid anode material exhibits a high initial coulombic efficiency of 80 % and a reversible capacity of 700 mAh g À1 after 100 discharge/charge cycles, an excellent cycle stability and a good rate performance.…”

SnO₂@TiO₂ Heterojunction Nanostructures for Lithium‐Ion Batteries and Self‐Powered UV Photodetectors with Improved Performances

To overcome the issue of inferior cycling stability and rate capacity for SnO2 anode materials in lithium‐ion batteries, an effective strategy is explored to prepare a hybrid material consisting of rutile SnO2 nanoparticles and rutile TiO2 nanorods, considering not only the small lattice mismatch to achieve a better composited lattice structure but also their superior synergistic effect in electrochemical performances. The as‐prepared SnO2@TiO2 material, directly formed on a carbon cloth as a binder‐free anode, exhibits a reversible capacity of 700 mAh g−1 after 100 discharge/charge cycles at 200 mA g−1, as well as excellent cycling stability and rate capacity. After being calcinated at high temperature, the produced hollow SnO2@TiO2 hybrid microtubes were directly used to fabricate photoelectrochemical (PEC) UV detectors for future devices with self‐powered function. A high photocurrent response of 0.1 mA cm−2 was observed, together with an excellent self‐powered and fast response and “visible blind” characteristics. Such a hybrid material could achieve a complementary effect in lithium‐ion batteries and a superior band gap match in photovoltaic devices, and could consequently be extended to applications such as dye‐sensitized solar cells and supercapacitors.
