Abstract
Study of carbon based solid state EDLCs at high sweep rates. C.K. Subramaniam, K. K. Cheralathan, G.Velayutham and Sri Bollepalli a Materials Division, School of Advanced Sciences, VIT University, Vellore, 632014, TN, INDIA. b Anabond Sainergy Fuel Cell India Pvt., Ltd., 288 Burma Colony, Perungudi Chennai 600096, INDIA. c Sainergy Tech, Inc., 869 Pickens Industrial Drive, Suite 11, Marietta, GA 30062,USA, Solid state carbon based Electrochemical Double Layer capacitors (EDLC) was assembled and cyclic voltammetry (CV) was studied at high sweep rates. The carbons used were Vulcan XC carbon with typical surface area of 260 m2/gm, templated mesoporous carbon, (CMK-3), typical surface area of 1260 m2/gm, and a blend of Vulcan XC carbon and mesoporous carbon (90:10 % by weight). Solid ionic polymers of perfluorosulphonic acid were used as electrolyte. CV was performed for scan rates as high as 800V/s. The polymer electrolyte membrane can support high scan rates.
