SU121158A1 - Alkaline Battery Sealing Method - Google Patents

Description

The known designs of alkaline batteries with bipolar electrodes located in separate cells of the battery have a significant disadvantage in leakage of the electrolyte in the places of seals, which leads to leakage of current and battery failure.

The described method of sealing batteries eliminates this drawback. This is achieved by pressing a row of steel conical shells inserted one into another, forming separate elements of the battery and isolated from each other by conical plastic rings.

The battery of such molded elements can be stretched with the help of pins or by crimping the edges of a steel cylindrical casing to maintain tightness.

The drawing shows a section of a battery, hermetically sealed according to the described method.

When pressed into each other with a gasket between them of the plastic insulating cap 2, the stamped tapered conductor bodies / conductors / form between them a sealed space — a cell. Inside each cell, positive and negative 3 c 4 impregnated in electrolyte are placed, separated by a separator 5. The bottom surface of each conductor casing is connected to the positive electrode on one side and the negative electrode on the other hand.

Thus, the conductor shells pressed into each other, on the one hand, form between themselves sealed cells of individual batteries, on the other hand, they serve as the conductor for connection No. 121158

Separate bipolar electrodes into a series battery circuit.

The height of the individual cells is provided by distance rings 6 mounted on the glue, which are placed between the flanges of the Corn-Cus pipes.

The battery column assembled from the required number of biller electrodes is compressed axially until the flanges of the conductor casing contact the distance rings, after which the battery is fully rolled or screwed into the case 7, which provides it with the necessary strength in operation. The positive and negative poles of the battery 8 to 9 are attached to the conductors at the pole in the pole.

The tightness of the battery cells is ensured by the exact mating of the surfaces of the stamped gokoprovod housings manufactured in the same die; sufficiently high purity of the surface of the housing-conductors made, for example, from light or polished tape; The small angle of the conical part of the conductor housings (8 ° -12 °) allows the transfer of significant radial forces to the insulating cap .2 placed between them, while ensuring the unbreakability of the connection. In addition, the contiguous parts of battery parts can be oiled with various epoxy, rubber no. 83, etc. adhesives.

As electrodes of batteries, both metal-ceramic-based electrodes and pressed nickel-cadmium powder electrodes can be used.
