Hydrothermal ammoniated treatment of PAN-graphite felt for vanadium redox flow battery

Influence of antimony ions in negative electrolyte on the electrochemical performance of vanadium redox flow batteries

“…Graphite felts (GFs) are the most widely used electrode materials in VRFB system, because they possess these advanced characteristics: low cost, high conductivity, good stability, strong corrosion resistance and high surface area [19][20][21][22]. However, their use as active electrode materials is still limited for their poor kinetics reversibility.…”

Synthesis of Low-Density Heat-Resisting Polystyrene/Graphite Composite Microspheres Used as Water Carrying Fracturing Proppants

“…The FTIR spectra of graphite, pure polystyrene and PS= graphite (2.5%) composite microsphere were shown in Figure 2a) at about 1652, 1561 and 1508 cm À1 , were attributed to the aromatic carbon skeleton stretching vibration [17] . As shown in Figure 2b, the peak at 3024 cm À1 corresponded to aromatic C-H stretching and the peak at 698 cm À1 belonged to the benzene C-H bending vibration.…”

Mn3O4 anchored on carbon nanotubes as an electrode reaction catalyst of V(IV)/V(V) couple for vanadium redox flow batteries

“…However, their electrochemical activity is not perfect enough. Therefore, a series of modification methods have been reported for enhancing the electrochemical properties of these carbon electrodes, such as acid treatment [16], electrochemical oxidation [17], thermal oxidation treatment [8], and introducing functional groups or metal elements [18][19][20]. However, these methods are not advantageous to commercial application because of the tedious synthesis procedures or the use of noble metals.…”
