The search for cleaner and more efficient energy storage and conversion technologies has become an urgent task due to increasing environmental issues and limited energy resources. The aim of energy storage and conversion is to obtain energy with environmental benefit, high efficiency, and low cost (namely, maximum atomic and recycling economy). Progress has been made in the fields of hydrogen storage and rechargeable batteries. The emerging nanotechnology offers great opportunities to improve the performance of existing energy storage systems. Applying nanoscale materials to energy storage offers a higher capacity compared to the bulk counterparts due to the unique properties of nanomaterials such as high surface areas, large surface-to-volume atom ratio, and size-confinement effect. In particular, one- dimensional (1D) inorganic nanostructures like tubes and wires exhibit superior electrochemical characteristics because of the combined advantages of small size and 1D morphology. Hydrogen and lithium can be stored in different 1D nanostructures in various ways, including physical and/or chemical sorption, intercalation, and electrochemical reactions. This review highlights some of the latest progress with the studies of hydrogen and lithium storage in inorganic nanotubes and nanowires such as MoS2, WS2, TiS2, BN, TiO2, MnO2, V2O5, Fe2O3, Co3O4, NiO, and SnO2.

TiO2-based materials have been widely studied in the field of photocatalysis, sensors, and solar cells. Besides that, TiO2-based materials are of great interest for energy storage and conversion devices, in particular rechargeable lithium ion batteries (LIBs). TiO2has significant advantage due to its low volume change (<4%) during Li ion insertion/desertions process, short paths for fast lithium ion diffusion, and large exposed surface offering more lithium insertion channels. However, the relatively low theoretical capacity and electrical conductivity of TiO2greatly hampered its practical application. Various strategies have been developed to solve these problems, such as designing different nanostructured TiO2to improve electronic conductivity, coating or combining TiO2with carbonaceous materials, incorporating metal oxides to enhance its capacity, and doping with cationic or anionic dopants to form more open channels and active sites for Li ion transport. This review is devoted to the recent progress in enhancing the LIBs performance of TiO2with various synthetic strategies and architectures control. Based on the lithium storage mechanism, we will also bring forward the existing challenges for future exploitation and development of TiO2-based anodes in energy storage, which would guide the development for rationally and efficiently designing more efficient TiO2-based LIBs anodes.
