Embodiment Construction

[0013] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited only to the examples.

[0014] combine figure 1 As shown, a novel cylindrical supercapacitor has a shell 4, and the upper and lower ends of the shell are all open structures. A battery cell 5 is arranged inside the shell 4 , and a lead-out terminal 1 is set at an upper opening of the shell, and the lower end of the lead-out terminal 1 is connected to the upper end of the battery cell 5 . An insulating sealing gasket 2 is provided between the upper side of the lead-out terminal 1 and the shell, and a sealing gasket 3 is set between the side of the lead-out terminal 1 and the inner wall of the shell 4; The solder joint 8 and the upper end of the electric core 5 are welded together through the current collector and the electric core.

Abstract

The invention discloses a novel cylindrical super capacitor. The capacitor possesses a shell. The shell is a structure with two open ends. An electrical core is arranged in the shell. An upper end opening of the shell is provided with a leading-out terminal. A lower end of the leading-out terminal is connected to an upper end of the electrical core. An insulation sealing gasket is arranged between an upper side surface of the leading-out terminal and the shell, and a sealing washer is arranged between a side portion of the leading-out terminal and an inner wall of the shell. A current collector is arranged in the leading-out terminal. A lower end of the current collector is welded with the electrical core through the current collector and an electrical core welding spot. A lower end opening of the shell is provided with an afflux leading-out terminal. The afflux leading-out terminal is welded with the electrical core through the current collector and the electrical core welding spot. The capacitor has advantages that the shell, the leading-out terminal, the electrical core and the afflux leading-out terminal are separated through the insulation sealing gasket or the sealing washer so that the shell is not charged completely, an electric leakage risk is reduced and a short circuit is not generated; two ends of the shell are connected so that installation and welding are convenient; and through the structure, die cost can be reduced.

Description

technical field [0001] The invention relates to the technical field related to capacitors, in particular to a novel cylindrical supercapacitor. Background technique [0002] A supercapacitor is an electrochemical component. There is no chemical reaction in the energy storage process, and the energy storage process is reversible. Therefore, the supercapacitor can be repeatedly charged and discharged hundreds of thousands of times without causing environmental pollution. In addition, it has a very high power density, which is 10-100 times that of the battery, suitable for short-term high power output, fast charging speed, simple mode, can be charged with high current, and can be charged within tens of seconds to minutes The process is fast charging in the true sense. As a new energy storage device with high power output and charging, its key structure is the connection structure of the super capacitor. [0003] Existing supercapacitors are generally open at one end, and the s...
