Hydrothermal synthesis of carbon/vanadium dioxide core–shell microspheres with good cycling performance in both organic and aqueous electrolytes

Electrochemical performance of B and M phases VO2 nanoflowers

“…The above data show that the discharge capacities of the VO 2 (B) nanoflowers is comparable to those reported for VO 2 (B) nanostructures [12,13], in the meanwhile, the shape of the curve for the B phase sample is exhibiting a flat plateau in the middle of the capacity range, which is similar to the reported result by Wang group [14], referring to lithium-ion de-intercalation and intercalation reactions.…”

Superior electrochemical properties of rutile VO2-carbon composite microspheres as a promising anode material for lithium ion batteries

“…Yan [34]. Spherical VO x -C composite materials have been scarcely prepared by conventional solution methods because of the rod-like crystal growth characteristics of vanadium oxide [35][36][37]. However, LIB applications generally require spherical micron sized powders with a narrow size distribution.…”

Hydrothermal synthesis of Li4Ti5O12/C nanostructured composites: Morphology and electrochemical performance

“…The hydrothermal (HT) synthesis of electrode materials shows the advantages over conventional methods for obtaining the particles of narrow size distribution and controlled morphology [17][18][19][20][21][22]. It was reported that carbon particles may serve as nucleation centers in the HT synthesis of LiFePO 4 [19], MnO 2 [20], and VO 2 [21], influencing also their electrochemical performance.…”

“…It was reported that carbon particles may serve as nucleation centers in the HT synthesis of LiFePO 4 [19], MnO 2 [20], and VO 2 [21], influencing also their electrochemical performance. Recently Lin and Duh [22] have used carbon black in HT reaction as a template for obtaining carbon free mesoporous LTO for high-rate lithium ion batteries.…”
