Abstract in different language: | The capacity of glassy carbon in aprotic salt solutions in propylene carbonate (PC) is investigated as an approach to the optimalisation of electrochemical supercapacitors. The strong influence of water residuum on capacities at negative potentials is indicated. The capacities exhibit a shallow minimum at potential from 0 V to +0.5 V (vss. Cd/Cd2+ reference electrode) and they increase with increasing electrolyte concentration. The admittance of the electrode in pure PC (as received) is by 2 – 3 orders of magnitude smaller. Undoubtedly, the properties of ions in solution influence the capacity by a factor not exceeding 2 to 5. |
