Ni(OH) 2 /CoO/reduced graphene oxide composites with excellent electrochemical properties

Ni(OH)2/CoO/rGO composites, which were synthesized via a one-step solvothermal route, exhibit excellent electrochemical properties, e.g., a specific capacitance up to 1317 F g−1 at a current density of 2 A g−1 and 1056 F g−1 at 5 mV s−1 with good cyclability.
