On the Mechanism of Selective Electroadsorption of Protons in the Pores of Carbon Molecular Sieves

Energy and power performance of vanadium carbide derived carbon electrode materials for supercapacitors

“…The mesopore volume increases and micropore volume decreases noticeably with increasing chlorination temperature higher than 1000°C [11]. These results are in a good agreement with the data for others carbide derived carbons prepared using the same chlorination method [3,4,6,[12][13][14][15][16][17][18][19][20].…”

“…All these properties as well as high electrical efficiency (up to 98%), high power density and good cyclability make supercapacitors useful in the power electronic systems and many fields of modern technology: military, space technology, transportation, lifting systems, etc. [7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

The contribution of sulfate ions and protons to the specific capacitance of microporous carbon monoliths

“…0.5 nm and 0.6-1 nm, respectively, have been reported [30,43,[45][46][47]. The proton size is still uncertain and the size seems to depend on the pH and counter ion [48][49][50]. To check how the S DFT surface area changes in relation to the size of the micropores, the sizes above 0.6, 0.75 and 1 nm were arbitrarily chosen and the S DFT values obtained for the three monoliths are shown in Table 1.…”

Energy and power performance of electrochemical double-layer capacitors based on molybdenum carbide derived carbon

“…On the other hand, the establishment of the adsorption equilibrium [8][9][10][16][17][18]30,31] in the micropores is a slow process. It is caused by the small "effective" diffusion coefficient values of ions in the micropores because of the distributed RC network [1,[7][8][9][10][30][31][32][33][34] within the porous C(Mo 2 C) electrode which can account for significantly hindered penetration depth of ions in smaller pores [7][8][9][10][11][12][16][17][18]. Therefore, C(Mo 2 C) carbons having narrow pore diameter cannot be used in peak power generation EDLCs due to the long charging/discharging times.…”

“…EDLCs are important energy storage systems, which can be used in various areas of modern technology starting from the pulse energy generation systems and finishing with the consumer goods [12][13][14][15]. Differently from batteries the EDLCs, based mainly on the electrostatic interactions, show good coulombic reversibility (from 97 to 99%) and excellent cyclability (over 10 6 cycles) [1][2][3][4][5][6].…”
