The recent scientific strategy is to manufacture environmentally friendly, low-cost, and flexible devices for powering miniaturized electronic systems, as well as portable and wearable electronic devices. In this context, this work presents a carbon based solid-state symmetrical supercapacitor with electrochemical performances relatively similar to those based on commercial carbon. Indeed, Biomass-derived electrodes were implemented with a quasi-solid-state electrolyte in an optimized sandwich structure using flexible substrates, to guarantee a combination of flexibility and low-cost aspect. The fabricated supercapacitor exhibits interesting electrochemical performances in terms of areal capacitance, power and energy densities comparing to the commercial carbon-based devices. According to the literature, the fabricated supercapacitor may be a promising candidate for microelectronic and wearable electronic applications. My name is Elyes BEL HADJ JRAD, I’m holding a master degree of research in electronic microsystems at the higher institute of applied sciences and technologies of Sousse. I am currently a PhD student in physics engineering at the Centre for Research on Microelectronics and Nanotechnology of Sousse (NANOMISENE laboratory). My thesis focuses on the study and development of ecological and low-cost supercapacitors based on green nanotechnology, for wearable electronics and microsystems applications.
