“…[295] Various efforts have been devoted to improve Li + diffusion rate and electronic conductivity of TiO 2 anodes, including constructing micro/nanostructure and composite structure (hybridization with carbon materials), surface modification (coating), defect engineering, and phase engineering. [295][296][297] Constructing materials with nanostructures is the most versatile method. Benefiting from the larger specific surface area and shorter Li + diffusion/electron transport pathway of 2D nanostructures compared with bulk materials, the construction of sheet-like TiO 2 has attracted considerable attention.…”

utilization of environmentally friendly renewable energy sources, such as solar energy, wind energy, and tidal energy. However, these renewable energy sources are intermittent in nature, which makes them unable to provide a stable energy supply. Therefore, energy storage devices play an integral role in setting up renewable energy systems. [1] At present, electrochemical energy storage (EES) technologies are the most commonly used due to high energy conversion efficiency, wide range of energy and power densities, relatively long lifetime, and low maintenance costs, among which lithium-ion batteries (LIBs) and supercapacitors (SCs) are considered to be the promising two. [2,3] LIBs, which have occupied half of the market of EES devices since their successful commercialization more than 30 years ago, have the advantages of high energy density, stable performance, and moderate cost, but their low power density and poor cycle performance are detrimental to fast and longterm energy storage. [4][5][6] By contrast, SCs, another excellent energy storage device, have the ability to store and release energy quickly and has an extremely long cycle life and good safety. The very limited energy density however greatly increases the number of equipment required to store the same energy, thus making SCs undesirable to meet the actual demand for high energy storage. [7][8][9] Consequently, in order to assist in realizing the vision of replacing nonrenewable fossil energy with environmentally friendly renewable energy, EES devices that can concurrently provide good energy density and high power performance are urgently needed.As a new type of EES device emerging after metal-ion batteries (MIBs) and SCs, metal-ion hybrid capacitors (MHCs) blessed with fabulous power performance, decent energy density, and remarkable cycle stability are considered to be one of the most prospective EES devices. [10] In 2001, the first MHC, using activated carbon (AC) as the cathode and nanostructured Li 4 Ti 5 O 12 (LTO) as the anode, was constructed by Amatucci et al., which possessed an energy density as high as 20 Wh kg −1 , about threefold than that of traditional SCs, showing promising rate capability in the meanwhile. [11] ThisThe design and development of advanced energy storage devices with good energy/power densities and remarkable cycle life has long been a research hotspot. Metal-ion hybrid capacitors (MHCs) are considered as emerging and highly prospective candidates deriving from the integrated merits of metal-ion batteries with high energy density and supercapacitors with excellent power output and cycling stability. The realization of high-performance MHCs needs to conquer the inevitable imbalance in reaction kinetics between anode and cathode with different energy storage mechanisms. Featured by large specific surface area, short ion diffusion distance, ameliorated in-plane charge transport kinetics, and tunable surface and/or interlayer structures, 2D nanomaterials provide a promising platform for manufacturing battery-type electrod...

TiO2 nanotube (TNT) is synthesized by a facile microwave method. Physical properties of TNT are characterized by transmission electron microscopy, X‐ray diffraction, Raman, thermal gravimetric analysis‐differential scanning calorimetry, X‐ray photoelectron spectroscopy, and nitrogen adsorption‐desorption. Meanwhile, the electrochemical and kinetic performances are investigated. TNT anode in lithium‐ion batteries exhibits a long cycling life (71 mAh g−1 after 20000 cycles at 3 A g−1), outstanding rate capability (123 mAh g−1 at 5 A g−1), and fast Li+‐transport (1.42×10−13 cm2 s−1 by EIS). Furthermore, TNT anode in dual‐ion batteries also displays superior cyclic stability (75 mAh g−1 after 1000 cycles at 0.5 A g−1).

The demand for power is increasing due to the rapid growth of the population. Therefore, energy harvesting (EH) from ambient sources has become popular. The reduction of power consumption in modern wireless systems provides a basis for the replacement of batteries with the electromagnetic energy harvesting (EMEH) approach. This study presents a general review of the EMEH techniques for autonomous sensor (ATS) applications. Electromagnetic devices show great potential when used to power such ATS technologies or convert mechanical energy to electrical energy. As its power source, this stage harvests ambient energy and features a self-starting and self-powered process without the use of batteries. Therefore, it consumes low power and is highly stable for harvesting energy from the environment with low ambient energy sources. The review highlights EMEH circuits, low power EMEH devices, power electronic converters, and controllers utilized in numerous applications, and described their impacts on energy conservation, benefits, and limitation. This study ultimately aims to suggest a smart, low-voltage electronic circuit for a low-power sensor that harvests electromagnetic energy. This review also focuses on various issues and suggestions of future EMEH for low power autonomous sensors.
