Acetylene black is made from acetylene carbon black. Because of acetylene black has excellent electric conductivity and large specific surface area, strong adsorption capacity, particle size is small and isotropic, and therefore is widely used for the field of electrochemistry and electrical analysis. This thesis were studied in the activated carbon, CNT, PTFE emulsion as main electrode materials on the basis of adding different proportions of acetylene black on the properties of super capacitor. Mainly includes the following aspects: (1)For super capacitor electrode slices and binder factors in producing method of exploration and experiment, the preparation of stable performance of super capacitor. (2)Studied to mix different electrode material affect the performance of capacitor, including specific capacity, ESR, basic properties, such as charge and discharge efficiency and carries on the comparative analysis. Key words: super capacitor; Electrode materials; The specific capacity; binder 目录 TO
