Abstract
The utility model relates to a super capacitor bottom cover. The super capacitor bottom cover comprises a sealing plate and a collector plate which is connected with the sealing plate. The center part of the sealing plate extends outward to form a boss. The center part of the boss extends outwards to form a pole. A step which matches a casing of a capacitor is arranged on the edge of the sealing plate. Laser welding is carried out on the sealing plate and the casing of the capacitor through the step on the edge to seal the capacitor. The super capacitor bottom cover provided by the utility model has the advantages that the bottom cover and the casing body of the super capacitor are separately designed, which is convenient for processing; laser welding is used for the capacitor, thus the sealing effect is great; and the super capacitor bottom cover is suitable for large capacitance.
Description
Technical field
The utility model relates to a kind of bottom of ultracapacitor.
Background technology
Ultracapacitor is the extraordinary energy-storage travelling wave tube between traditional capacitor and electrochemical power source that development in recent years is got up, because it has advantages of that power density is high, service life cycle is long and charging rate is fast, can be applied in multiple fields, have broad application prospects.But existing ultracapacitor comprises housing, cover plate and with housing be the bottom of an overall construction design, this design is processed complex but also difficult operation not only.
Utility model content
The purpose of this utility model is to provide a kind of bottom of ultracapacitor, to overcome currently available technology above shortcomings.
