Embodiment Construction

[0022] As shown in Figures 1, 2, and 3, the seal of a kind of alkaline zinc-manganese battery of the present invention comprises spot welding pin 1, current collector 2, has indium-plated small bowl 3, spot welding pin 1 to insert sealing ring 4 In the middle hole, the indium-plated small bowl 3 tightens the insertion part of the spot welding needle 1 in the middle hole of the sealing ring 4 to form the current collector 2, and the current collector 2 is inserted into the zinc paste 5 of the battery, and the expansion of the nickel-plated steel shell 6 Mouth site 7 is a tight fit.

[0023] The aforementioned spot welding needle 1 is formed by welding the negative electrode cover 8 and the indium-plated copper needle 9 .

[0024] The stressed surface of the above-mentioned sealing ring 4 has two longitudinal and transverse sealing and anti-leakage defense lines 10, 11, and the pressure that the sealing ring 4 bears is 4.5 MPa.

[0025] The above-mentioned sealing ring 4 is mad...

Abstract

This invention relates to a sealing and its manufacturing method for alkali ZnMn cells, in which, the sealing includes a spot-welding pin, a collector and a small bowl plated with In, and the spot-welding pin is plugged into a mid hole in a sealing ring, the small bowl hoops the part for plugging the pin of the mid hole tightly to form a collector, which is plugged into a Zn paste to match with the flaring part of a Ni-plated steel shell. The manufacturing method includes: extruding two sealed leak-proof lines longitudinally and horizontally to the forced side of a sealing ring of the flaring part of the steel shell, and shaping the sealing ring horizontally and blanking longitudinally supported by a negative cover.

Description

Technical field: [0001] The invention belongs to the technical field of methods or devices for directly converting chemical energy into electrical energy, and in particular relates to a sealing of an alkaline zinc-manganese battery and a manufacturing method thereof. Background technique: [0002] Alkaline zinc-manganese batteries use KOH aqueous solution as the electrolyte solution of this type of battery, and KOH solution has the characteristic of good wettability when it gets along with metal substances (steel shell). Coupled with the high internal pressure of the battery, the alkaline battery is extremely prone to alkali leakage. For alkaline zinc-manganese batteries, there are often gases inside the battery such as CO 2 、H 2 etc. When the battery is heated, the internal gas expands, causing the internal pressure of the battery to increase, and there is a possibility of explosion. The sealing ring of the battery has two explosion-proof grooves. When the internal press...
