Characterization of pistachio shell-derived carbons activated by a combination of KOH and CO2 for electric double-layer capacitors

Cyclic Voltammometry of Binderless Activated Carbon Monoliths based supercapacitor from Mixtures of Pre-carbonized of Fibers of Empty Fruit Bunches and Green Petroleum Coke

“…Compared to the holding time of activation of 1 hour [9], the holding time of activation of 1.5 and 2 hours were very effective to improve the performance of supercapacitor. Hu et al reported that the effect of activation of CO 2 [10] and holding time of activation of carbon electrodes could eliminate the redox peaks as observed in our study.…”

“…Consequently, the square characteristic of potential window decrease resulted from ain order pore structure, andhighly unordered pore network [16]. CV slowly becomes tilted from the horizontal line as the scan rate increase, which indicates the value of ESR significantly increase because of ionic conductivity of H 2 SO 4 electrolyte becomes to be smaller [10].…”

Cherry stones as precursor of activated carbons for supercapacitors

“…The search for lower-cost carbons is a priority and lignocellulosic wastes have become interesting candidates for electrochemical applications [8][9][10][11][12][13].…”

Effect of poly(3,4-ethylenedioxythiophene) (PEDOT) in carbon-based composite electrodes for electrochemical supercapacitors

“…An EDLC stores the energy by accumulating the opposite charges on the thin double layer (5~10Å) [2] at the interface between the porous electrode and the electrolyte through electrostatic force. Carbonaceous materials such as aerogel [3][4] and powder [5] [6] are the most commonly used electrode materials in EDLC devices due to carbon's high surface area, chemical and thermal stability, relatively low cost and low environmental impact. Carbonaceous materials are usually activated [4] [7] to produce a large porous surface area before being used for EDLC electrodes.…”
