| Abstract: | An improved by G1 algorithm for solving the integral equations electrochemical numerical simulation method is reported. This method was applied successfully to simulate fast cyclic voltammograms with existing of the uncompensated solution resistance (R u) and double layer capacitance (C dl ). The influence of R u , the coupling of charging and faradaic currents were investigated. Effectiveness of the correction method by using effective potentials and the background subtraction method was discussed. |
