“…Due to the high energy surface of TiO 2 , the nanoparticles show a tendency to selfaggregate during the charge-discharge process, and this is the main cause of the decay of the capacity upon cycling [73]. The best results have been obtained with special morphologies that avoid this irregular aggregation: one example is hollow nanostructures composed of nanosized primary building blocks [74].…”

International audienceAnatase TiO2 nanoparticles were prepared by a simple sol-gel method at moderate temperature. X-ray powder diffraction (XRD) and Raman spectroscopy revealed the exclusive presence of anatase TiO2 without impurities such as rutile or brookite TiO2. Thermogravimetric analysis confirmed the formation of TiO2 at about 400 °C. Particle size of about 20 nm observed by transmission electron microscopy matches well with the dimension of crystallites calculated from XRD. The electrochemical tests of the sol-gel-prepared anatase TiO2 show promising results as electrode for lithium-ion batteries with a stable specific capacity of 174 mAh g−1 after 30 cycles at C/10 rate. The results show that improvement of the electrochemical properties of TiO2 to reach the performance required for use as an electrode for lithium-ion batteries requires not only nanosized porous particles but also a morphology that prevents the self-aggregation of the particles during cycling

“…To address these issues, rechargeable sodium-ion batteries (NIBs) are proposed as a potential candidate for large-scale energy storage due to the natural abundance and lower cost of sodium 7,8 . For the NIB anode materials, much effort has been focused on low-voltage metal oxide anodes, among which, TiO 2 has attracted considerable attention 2,[9][10][11][12][13] due to its low operation voltage, high capacity, nontoxicity, and low production cost.…”

Sodium-ion batteries are considered to be a promising low-cost alternative to common lithium-ion batteries in the areas where specific energy is less critical. Among all the anode materials studied so far, TiO2 is very promsing due to its low operation voltage, high capacity, nontoxicity, and low production cost. Herein, we present Nb-doped anatase TiO2 nanoparticles with high capacity, excellent cycling performance, and excellent rate capability. The optimized Nb-doped TiO2 anode delivers a high reversible capacity of 177 mAh/g at 0.1 C and 108.8 mAh/g at 5 C, in contrast to 150.4 mAh/g at 0.1 C and only 54.6 mAh/g at 5 C for the pristine TiO2. The good performance is likely to be associated with enhanced conductivity and lattice expansion due to Nb doping. These results, in combination with its environmental friendliness and cost efficiency, render Nb-doped TiO2 a promising anode material for high-power sodium-ion batteries.Nb-doped anatase TiO 2 anode materials with high reversible sodium storage capacities, excellent cycling stability and rate capability were synthesized by sol-gel method.

“…Besides the 3D architectures of MoS 2 with carbonaceous materials, recently 3D networks of MoS 2 have also been prepared with TiO 2 microspheres to enhance the electrochemical performance of LIBs [86]. For instance, a firework shaped TiO 2 (3D F-TiO 2 ) microspheres have been used as template, in which 3D F-TiO 2 microspheres were embedded with MoS 2 NSs by two step hydrothermal methods [86].…”

Abstract:With an ever increasing energy demand and environmental issues, many state-of-the-art nanostructured electrode materials have been developed for energy storage devices and they include batteries, supercapacitors and fuel cells. Among these electrode materials, L-TMD (layered transition metal dichalcogenide) nanosheets (especially, S (sulfur) and Se (selenium) based dichalcogenides) have received a lot of attention due to their intriguing layered structure for enhanced electrochemical properties. L-TMD composites have recently been investigated not only as a main charge storage specie but also, as a substrate to hold the active specie. This review highlights the recent advancements in L-TMD composites with 0D (0-dimensional), 1D, 2D, 3D and various forms of carbon structures and their potential applications in LIB (lithium ion battery) and SIB (sodium ion battery).
