The present invention relates to a rechargeable power source comprising a flexible supercapacitor and a charge connection unit. The flexible supercapacitor comprises an electrolyte sandwiched between nickel foams electrodeposited with a nanocomposite. The nanocomposite comprises of a conducting polymer, graphene oxide and a metal oxide. The charge connection unit comprises a microcontroller having an electrical connection line connecting an energy collecting unit with the flexible supercapacitor.

Rechargeable power source comprising flexible supercapacitor

A flexible supercapacitor comprising an electrolyte sandwiched between nickel foams electrodeposited with a nano-composite. The nanocomposite comprises of a conducting polymer, graphene oxide and a metal oxide. Process of fabricating the flexible supercapacitor is also provided. The process comprises electrodepositing a nanocomposite electro-potentiostatically on a nickel foam from an aqueous solution comprising of a conducting monomer, graphene oxide and a metal salt, placed in one compartment cell followed by compressing an electrolyte between at least two layers of electrodeposited nickel foams.
