Elaboration of a microstructured inkjet-printed carbon electrochemical capacitor

a b s t r a c t Carbon-based micro-supercapacitors dedicated to energy storage in self-powered modules were fabricated with inkjet printing technology on silicon substrate.Aninkwasfirst prepared by mixing an activated carbon powder with a PTFE polymer binder in ethylene glycol stabilized with a surfactant then deposited by inkjet on patterned gold current collectors with the substrate heate…
