Embodiment Construction

[0010] Embodiments are described in detail with reference to the accompanying drawings. A nickel-hydrogen button battery negative electrode cover, the edge of the nickel-hydrogen button battery negative electrode cover 1 is a flange 2 structure. The nickel-hydrogen button battery of the present invention includes a negative electrode cover 1 , and the edge of the negative electrode cover 1 is a flange 2 structure. The nickel-hydrogen button battery is composed of a plate set 10, a conical coil spring 3, a negative electrode cover 1, a rubber ring 5 and a positive steel shell 9. The plate set 10 is made of a connecting piece structure or a single piece It consists of a nickel positive plate 8, a hydrogen storage alloy negative plate 6 and a diaphragm 7 arranged between the positive plate and the negative plate. The specific combination method is: (1), first combine the negative electrode cover 1 with the flanging 2 structure and the rubber ring 5 with the snap ring; (2), put t...

Abstract

The invention discloses a hydrogen-nickel buckle type battery and a negative pole cover thereof. According to the main points of the technical scheme provided by the invention, the negative pole cover of the hydrogen-nickel buckle type battery is characterized in that an edge of the negative pole cover is in a turnover edge structure. The hydrogen-nickel buckle type battery comprises the negative pole cover; and the edge of the negative pole cover is in the turnover edge structure. According to the hydrogen-nickel buckle type battery and the negative pole cover thereof provided by the invention, the edge of the negative pole cover of the hydrogen-nickel buckle type battery is in the turnover edge structure, so that the sealing cross section of the hydrogen-nickel buckle type battery is enlarged; the sealing pressure is increased by increasing the area of the sealing cross section; the sealing property of the battery is improved; and the possibility of liquid leakage and creepage of the battery can be reduced.

Description

technical field [0001] The invention belongs to the technical field of button batteries, and in particular relates to a negative electrode cover of a nickel-hydrogen button battery and a nickel-hydrogen button battery. Background technique [0002] Due to its small size, the nickel-hydrogen nickel button battery cannot be sealed with a rolling groove sealing structure like a cylindrical battery, and the battery can only be sealed by a small amount of compression of the sealing ring by the battery case cover. At present, the sealing structure of the hydrogen-nickel button battery is a linear seal, and the sealing pressure is relatively small, so the battery is prone to alkali leakage. Therefore, the current sealing structure must be changed to solve the leakage and alkali climbing problem of the nickel-hydrogen button cell. At present, the negative electrode cover with flanging structure is only used in the sealing structure of disposable button batteries, and there is n...
