Abstract
This paper reports on the electrochemical performance of symmetric electrochemical capacitors operating in an aqueous electrolyte (1 mol L−1 Li2SO4 solution) whose viscosity is modified by various amounts of carboxymethyl cellulose additive.

This paper reports on the electrochemical performance of symmetric carbon/carbon electrochemical capacitors operating in an aqueous electrolyte (1 mol LÀ1 Li2SO4 solution) whose viscosity is modified by various amounts of carboxymethyl cellulose additive
In this article, we present that the impact of the electrolyte viscosity on the electrochemical capacitor energy and power performance is determined by the pore structure of carbon and pore accessibility
Summary
Energy generation and consumption are currently among the most important economic and social considerations, especially in highly developed countries. All these processes will lead to a reduction in voltage and a loss of stored energy of the charged device Several solutions to this problem have been proposed, including the formation of an insulating layer on the electrode by depositing a thin lm of poly(p-phenylene oxide).[53] Another method is to use an ionexchange membrane for active redox[54] or addition of surfactants to the electrolyte.[55] Due to the long alkyl chain, surfactants adsorbed on the surface of the electrode should serve as a micro-insulator and hinder the ow of discharge current. The obtained result provides new insights into the problem of electrolyte viscosity and shows that viscosity itself is not the limiting parameter
