Progress on One-dimensional Vanadium Pentoxide-based Nanomaterials for Advanced Energy Storage ANSTEEL Research Institute of Vanadium & Titanium (Iron & Steel), China.

One-dimensional (1D) vanadium-based nanostructures have advantageous properties and are showing emerging critical applications in the fields of catalysis, smart devices, and electrochemical energy storage. We herein timely gave an overview of the 1D vanadium pentoxide (VO)-based nanomaterials for these promising applications, especially regarding the merits of different synthetic methods, structures and properties combined with recent research frontiers in advanced energy storage, including batteries, supercapacitors and like. The high capacity, high rate and flexibility of 1D VO-based nanomaterials endow them with great potential in high-energy-density, high-power energy devices and specific/harsh environments.

Low-Dimensional Vanadium-Based High-Voltage Cathode Materials for Promising Rechargeable Alkali-Ion Batteries.

Owing to their rich structural chemistry and unique electrochemical properties, vanadium-based materials, especially the low-dimensional ones, are showing promising applications in energy storage and conversion. In this invited review, low-dimensional vanadium-based materials (including 0D, 1D, and 2D nanostructures of vanadium-containing oxides, polyanions, and mixed-polyanions) and their emerging applications in advanced alkali-metal-ion batteries (e.g.

A Review: Synthesis and Applications of Titanium Sub-Oxides.

Magnéli phase titanium oxides, also called titanium sub-oxides (TiO, 4 < n < 9), are a series of electrically conducting ceramic materials. The synthesis and applications of these materials have recently attracted tremendous attention because of their applications in a number of existing and emerging areas. Titanium sub-oxides are generally synthesized through the reduction of titanium dioxide using hydrogen, carbon, metals or metal hydrides as reduction agents.

Dicyandiamide-assisted synthesis of N-doped porous CoMn-Nx@N-C carbon nanotube composites MOFs as efficient trifunctional electrocatalysts in the same electrolyte.

The development of low-cost, long-term stability, and good oxygen reversible catalytic reaction (ORR/OER) and hydrogen evolution (HER) activity under the same electrolyte concentration of electrocatalytic materials has an important role in the construction of large-scale applications and more valuable sustainable energy systems. Among them, the representative CoMn-Nx@N-C-900-0.2 showed good ORR/OER/HER catalytic activity in 0.

Research progress on ZnSe and ZnTe anodes for rechargeable batteries.

Transition-metal chalcogenides (TMCs) with tunable direct bandgaps and interlayer spacing are attractive for energy-related applications. Semiconducting zinc chalcogenides, especially their selenides (ZnSe) and tellurides (ZnTe), with enhanced conductivity, high theoretical capacity, low operation voltage and abundance, have appeared on the horizon and receive increasing interest in terms of electrochemical energy storage and conversion. Despite the existing typical obstruction owing to the large volume change, relatively low electrical conductivity and sluggish ion diffusion kinetics into the bulk phase, several effective strategies such as compositing, doping, nanostructuring, and electrode/cell design have exhibited promising applications.
