Abstract

The invention discloses a cover plate of a supercapacitor, relates to an improved technology of an electronic element, and particularly relates to an improved technology of a capacitor. The cover plate is characterized in that a cell is put in an aluminum shell; positive and negative current collecting pieces are arranged on the upper and lower parts of the cell respectively; an upper aluminum cover is arranged on the top of the aluminum shell; a groove is formed in the edge of the aluminum cover; a ceramic insulating ring is arranged in a contact position between the groove and the aluminum shell; the ceramic insulating coil consists of an inner ceramic ring and an outer aluminum ring; the inner ceramic ring and the groove are matched in outlines; the gap between the inner ceramic ring and the aluminum cover is leveled up by the outer aluminum ring; and the upper aluminum cover, the outer aluminum ring and the ceramic ring are fused by adopting a braze welding technology. The cover plate is firm in structural member, high in torsion and compression resistance, high in air-tightness, resistant to high temperature, high in low-temperature performance and high in insulation value.

Description

technical field [0001] The invention relates to an improvement technology of an electronic component, in particular to an improvement technology of a capacitor. Background technique [0002] At present, the supercapacitor mainly includes a battery cell, a positive current collector, a negative current collector, an upper aluminum cover, an aluminum shell, an O-ring and an insulating ring. The positive and negative current collectors are connected to the battery core by laser welding, and the negative collector The flow sheet is directly inserted into the aluminum cover and connected to the aluminum shell cover plate by rolling. The positive current collector is connected to the cover plate by adding a spacer ring and an O-shaped sealing ring by rolling. The cover plate is the window for the internal energy to connect with the outside. , plays the most important position of energy transmission and safety check, so it is very important to develop a functional "cover plate". Th...
