The electrochemical performance of capacitor affected by the presence of materials in terms of energy and power densities, rate capacity, cyclic life. Carbon nanotubes(CNT) has many advantages(high mechanical, thermal stability, high thermal conductivity and large current carrying capacity). In this study, acid treatment were change to carboxylic acid groups on CNT. And then used of surfactant, made water in oil phase of micelle. centrifugation and calcinations to the micelle phase CNT. We made a microsphere CNT. As a result, CNT give exceptional improvement of electrode performance due to their mesoporous and well conducting networks. The cell resistance is drastically reduced and the transport of ions is greatly enhanced. |
