State-of-arts of research and development of supercapacitor, a novel energy storag e component

The operating principle and structure characteristics of supercapacitor are introduced, and the state of arts of its developments and industrialization at home and abroad are reviewed. Supercapacitor is a novel energy storage component developed in recent years. It integrates the advantages, such as the high power density characterized by conventional capacitors, the energy density characterized by rechargeable batteries, the fast charge/discharge performance and the long life, thus the component is expected to be a novel power source with high efficiency and practicability. The operating principle and structure characteristics of supercapacitor are different from those of conventional capacitors. It consists of polarized electrode, collector, electrolyte, separator, lead and packing material, and its performances are affected by the composition and structure of each component greatly.
