Abstract: Supercapacitors, benefited from superb energy and power characteristics, have now drawn intensive interest for their capability of meeting the above requirements. However, traditional materials for supercapacitor electrodes such as activated carbon and metal oxide/hydroxides suffer either a low energy density or poor power input/output rate. The work presented here offer a new strategy to develop novel composites based on carbon nanotubes (CNT) to utilize the synergistic effects of both carbon host and pseudocapacitive guest materials. The main focus is located on how CNT structures with different dimensions affect the device performance. The 0 D particle-like, 2D film-structured and 3D gel-assembled CNT composites have been thoroughly investigated. It is found that CNT structures with higher dimensions are significant in preventing the agglomeration of active materials and improving the electrical conductivity, leading to satisfactory electrochemical performance.
