Description:
Supercapacitors have higher power density than conventional batteries and a higher energy density than regular capacitors. They have proven invaluable for grid energy storage systems, especially with the upcoming intermittent renewable energy sources. This technology has developed a novel transition metal oxide for electrochemical capacitors ‘supercapacitors’ that is a core-shell nanostructure composed of a vanadium oxide core and an electronically active phase nanoshell.
Reference Number: D-1085
Market Applications:
- Transportation, industrial, and energy storage industries
- Grid energy storage systems, especially with the upcoming intermittent renewable energy sources.
Features, Benefits, & Advantages:
This technology discloses a new vanadium oxides core/shell nanostructure based electrode to overcome the resistivity challenge of transition metal oxides (TMOs) for rapid pseudocapacitive electrochemical (EC) supercapacitor design. The design employs graphene sheets as the conductive framework, anchored with quasi-metallic conductive V2O3 as nano-cores that are further encapsulated with VOx acting as active oxides.
- Increased power density in supercapacitors while maintaining energy density
- Improved charge-discharge rate by 100 times
