ABUSE CAPACITOR HAVING WIDE TEMPERATURE RANGE, AND MANUFACTURING METHOD THEREFOR

摘要

Disclosed in the present invention an abuse capacitor having a wide temperature range, and a manufacturing method therefor. A pole piece of the abuse super capacitor is prepared from a current collector containing carbon or a high conducting polymer and a mesoporous carbon material. A membrane of the abuse super capacitor is a hydrophilic membrane. An electrolyte of the abuse super capacitor is an ionic liquid electrolyte or a mixed electrolyte of an ionic liquid and an organic solvent. The stable working voltage range of the super capacitor is 0 V to 10 V, and the stable working temperature range of the super capacitor is minus 90 degrees centigrade to 300 degrees centigrade; the ionic liquid electrolyte is nontoxic, free of pollution and free of combustion; sources of available membranes are wide in variety; and the abuse capacitor is a safe and environmentally-friendly abuse super capacitor having a high energy density in a real sense.
