The facile hydrothermal synthesis of a patronite VS 4 /single‐walled carbon nanotube/reduced graphene oxide hybrid is reported. Detailed electrochemical investigations of the hybrid revealed an exceptionally high energy density of ca. 174 W h/kg. A comparison of this value with those of other supercapacitor electrodes based on metal sulfides and also some with high energy‐density values revealed the potential of the patronite hybrid as a fitting candidate for possible application in energy‐storage devices. Charge–discharge stability measurements showed the excellent specific capacitance of the hybrid, which has a retention capability of ca. 97 % after 1000 continuous charge–discharge cycles.
