Herein, we report the hybrid structure of metallic VSe(2)and multi-walled carbon nanotube (MWCNT) based hybrid materials for high performance energy storage and high power operation applications. The dominance of capacitive energy storage performance behaviour of VSe2/MWCNT hybrids is observed. A symmetric supercapacitor cell device fabricated using VSe2/80 mg MWCNT delivered a high energy density of 46.66 W h kg(-1)and a maximum power density of 14.4 kW kg(-1)with a stable cyclic operation of 87% after 5000 cycles in an aqueous electrolyte. Using density functional theory calculations we have presented structural and electronic properties of the hybrid VSe2/MWCNT structure. Enhanced states near the Fermi level and higher quantum capacitance for the hybrid structure contribute towards higher energy and power density for the nanotube/VSe2.
