An active contribution: The specific capacitance of carbon-based supercapacitors can be significantly improved by the addition an electrochemically compound (hydroquinone) to supporting electrolyte. strong contribution redox-active electrolyte pseudocapacitance system results in largest values obtained for activated supercapacitor. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made...
The mechanisms involved in the storage of energy carbon-based supercapacitors modified by addition an electrochemically active compound (quinone/hydroquinone, Q/HQ) into electrolyte (H2SO4) are investigated. Besides charging double-layer characteristic carbon materials, galvanostatic cycling experiments performed on each electrode revealed a battery-type behavior anode and pseudocapacitive hydrogen electrosorption process cathode as consequence asymmetric split voltage between electrodes...
The proliferation of novel types and designs electrochemical capacitors makes it necessary to obtain a better understanding the behavior these systems together with more systematic classification them.
A graphite felt decorated with bismuth nanoparticles was studied as negative electrode in a vanadium redox flow battery (VRFB). The results confirm the excellent electrochemical performance of modified terms reversibility V(3+) /V(2+) reactions and its long-term cycling performance. Moreover mechanism that explains role Bi play this half-cell is proposed. favor formation BiHx , an intermediate reduces to V(2+) and, therefore, inhibits competitive irreversible reaction hydrogen (responsible...
A pyrolysis product derived from a coal-tar pitch was chemically activated using KOH in KOH/carbon proportion of 5:1. The carbon used as electrode-active material for capacitive deionization (CDI). Electrochemical parameters, such current values, charge, specific charge and charge−discharge efficiencies were investigated unit cell solutions NaCl different concentrations. parent shows an excellent behavior CDI, removing more salt than other carbons previously described the literature....
This work describes the chemical activation of a coke using two different activating agents to investigate their behavior as electrodes in supercapacitors. A was chemically activated with hydroxides (KOH and NaOH) under nitrogen flow, at constant mass hydroxide/coke ratio 2 temperatures 600, 650, 700 °C. All samples were characterized terms porosity by N2 sorption 77 K, surface chemistry temperature-programmed desorption (TPD), electrical conductivity. Their electrochemical electric...
