MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202511018936 A) filed by Kumaun University; and Kurukshetra University on March 03, 2025, for Zncl2 Activated Nano Carbon Soot And Composites With Waste Plastic Derived Graphene For Supercapacitor Application Thereof.
Inventors include Suman Mahendia; Nanda Gopal Sahoo; Manoj Karakoti; and Ritu Jangra.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention relates to a method for synthesis and characterization of hierarchical porous activated nitrogen-doped carbon from pyrolysis of dried marigold flower precursor as an effect of different impregnation zinc chloride (ZnCl2) (1:1, 1:3 and 1:5), referred as, FZ11, FZ13, and FZ15. The BET and FESEM results show the enhancement in porosity and surface area with activation with highest specific surface area of 1274.45m2/g for FZ15. The XPS confirms the engineering of nitrogen content into functional nitrogen doped sites upon the action of ZnCl2 activation as N-reservoir which results in increase in specific capacitance of fabricated symmetric cell, without any conductive black, increases with activation and shows the highest specific capacitance of 179 F/g, energy density of 23 Wh/Kg and power density of 556 W/Kg for FZ15 sample. Addition of carbon black helps in lowering ESR to 0.77 O and enhancement in energy density and series combination of 3 such cells glow yellow LED for ~3 minutes.
