“…Thus, V 2 O 3 has received increasing interest in recent years and has lots of promising properties for various applications, such as intelligent windows [25], field effect transistors [25], aqueous lithium ion batteries [27,28], supercapacitors [29], temperature sensors [30], conductive composite polymer [31], catalyst [32] and so on. Therefore, in past decades, many routes have been performed to synthesize V 2 O 3 , including O 2 eH 2 flame fusion [33], evaporative decomposition and H 2 reduction [34], pyrolysis [35], nonaqueous route [36], supercritical fluid [37] and hydrothermal method [38]. However, only bulk V 2 O 3 powders or spherical V 2 O 3 nanopowders are obtained by these methods.…”

“…The V-doped LFP samples made herein via CHFS have been obtained starting from a V 4+ salt (VOSO4) in a reducing environment resulting from the partial breakdown of fructose (the carbon source) under the extreme hydrothermal conditions. Vanadyl salts alone in similar synthetic conditions can reduce to V 3+ (V2O3) [46]. Therefore, the presence of V 5+ in the samples is counterintuitive and needs understanding.…”

A high performance vanadium-doped LiFePO4 (LFP) electrode is synthesized using a continuous hydrothermal method at a rate of 6 kg per day. The supercritical water solvent rapidly generates core/shell nanoparticles with a thin, continuous carbon coating on the surface of LFP, which aids electron transport dynamics across the particle surface. Vanadium dopant concentration has a profound effect on the performance of LFP, where the composition LiFe0.95V0.05PO4 achieves a specific discharge capacity which is among the highest in the literature (119 mA h g-1 at a discharge rate of 1500 mA g-1). Additionally, a combination of Xray absorption spectroscopy analysis and hybrid-exchange density functional theory suggest that vanadium ions replace both phosphorous and iron in the structure, thereby facilitating Li + diffusion due to Li + vacancy generation and changes in the crystal structure.

“…71 V 2 O 3 shows a much larger size with several micrometers, and the morphologies of the V 2 O 3 particles were micrometer layered structures that were assembled by nanometer or micrometer sheets. Tao et al 72 reported that the V 2 O 3 nanoparticles had been synthesized by supercritical ethanol fluid reduction of VOC 2 O 4 with an average size of 50 μm. Madanagurusamy et al employed the oxidation way to obtain the V 2 O 3 nanosheets.…”
