A New Benchmark Capacitance for Supercapacitor Anodes by Mixed‐Valence Sulfur‐Doped V6O13−x. (30th July 2014) - Zhai, Teng
Abstract A new pseudocapacitor anode, sulfur‐doped V6O13−x, is reported. It achieves a benchmark capacitance of 1353 F/g (0.72 F/cm2) at a current density of 1.9 A/g (1 mA/cm2) in 5 M LiCl solution. The charges are stored chemically in the electrode via reversible redox reactions that involve multiple oxidation states of vanadium (V3+, V4+ and V5+).
