Carbon Nano tubes (CNTs) have outstanding physical properties such as a large specific surface area, chemical stability and high electrical conductivity as an electrode active material for electrochemical energy storage device. And heat resistance and surface area per unit volume is large. In this study, after dispersed in aqua regia CNTs and then used of Polystyrene microspheres (PS), made an aggregation CNTs. The spherical CNTs composited material was prepared with PS to increase the electrical conductivity and the electrode surface. The physical properties of the CNTs were investigated using the BET and SEM. And the electrochemical properties of CNTs-PS composite materials were measured with CV, Impedance and Charge/Discharge test. |
