Abstract

This project investigated the performance of the supercacitor using carbon electrodes with an aprotic electrolyte Lithium Perchlorate (L1CIO4) salt in Acetonitrile solvent. The experiments were done to study the life cycle, the voltage profiles and the capacitance profiles of this new assembled supercapacitor test cell. The samples used in these experiments are VGAF SHOW A DENKO and TIMREX HSAG 100 CAT Special Graphite M292. The methodology used in this experiment was the identification of equipments and items needed, material testing, running the experiments and conclusion offindings. The width ofthe electrochemical stability window oforganic solvents is wide often exceeding 2 V that will be used in this experiment. The test cells assembled in these experiments were tested within the range of applied currents of 0.001A, 0.005A, 0.01A and 0.05A. In conclusion, this experiment showed that the specific capacities of the samples tested are highest when the current applied is at the lowest value of 0.001A. In the case of the first experiment, the specific capacity was 3.51mAh/g and in the second experiment, it was 5.83mAh/g .The voltage profile also shows that the samples are more stable at a lower applied current value of0.001A.
