RU13851U1 - AIR AND METAL BATTERY - Google Patents

Description

The utility model relates to the field of electrical engineering and can be used in the manufacture of air-metal batteries.

Known air-metal battery, adopted as a prototype, made of series-connected elements, containing cathode assemblies in the form of box-shaped structures with gas diffusion cathodes located on opposite walls of each of the assemblies, and a collector, connected to one of the end walls of each assembly, placed inside cathode assemblies anode plates made of active metal or alloy with current leads, framed by spring contacts, connected to conductors with current leads, respectively one assembly (see USSR patent 1801233 A3, class H01M 12/06, 03/07/1993).

A disadvantage of the known battery is its low electrical performance due to the increased dimensions of the battery and the difficulty of its operation, associated with the need to individually remove the anodes from each cathode assembly of the battery during interruptions in operation, which increases the service time.

The claimed technical result is achieved by the fact that an air-metal battery of series-connected elements, containing cathode assemblies in the form of box-shaped assemblies with electrical circuits with ion cathodes located on opposite walls of the caddas from the assemblies, and down conductors connected to one from the ends of the walls to each assembly, the anode plates of the active metal or alloy will be placed inside the assembly of assemblies with current leads fixed by spring contacts connected by conductors to current leads corresponding to todnyh assemblies. In this case, the battery is equipped with side walls, equipped with ear retainers of the position of the elements for forming the battery and grooves in the upper part from the inside for fastening the consumer load. Adjacent planes of the cells are provided with locking latches, which ensure the framing of the battery. The battery cover is provided with holes for the passage of the anode down conductors and their fixation on the flashlight with U-shaped spring contacts, as well as holes for charging the electrolyte and gas outlet and contact plate plates} to connect the load.

The presence in the battery of side walls, a cover for mounting anodes and switching elements, as well as latches on the walls of the cathode assemblies and side walls, significantly reduces the dimensions of the battery and, accordingly, increases the specific electrical characteristics. The fastening of all anodes on the battery cover significantly simplifies the operation of the battery and reduces the time of its maintenance, since when activated and interruptions in operation are installed or removed immediately

An analysis of the prior art showed that the claimed combination of essential features outlined in the utility model formula is unknown. This allows us to conclude that it meets the criterion of novelty

The essence of the utility model is illustrated in the drawing--. In FIG. 1A is a side view of a battery with a cross section of one cell. In FIG. 1B shows a cross-section of the battery along line AA. In FIG. 1B, a cross-sectional view of an element along BB line is shown.

BC A metal-air battery consists of electrically connected elements 1, each of which contains a cathode assembly 2 with gas diffusion cathodes 3 and a collector 4 brought to the end wall in the upper part and the anode plate 5 located inside the cathode assembly with a collector 6. Anode plate Е1 mounted on the cover 12 using a U-shaped spring contact 7 connected by conductors 8 with a down conductor 4 of the adjacent cathode assembly. The cathode assemblies are assembled into the battery by means of clamps 11 and side walls 12. The clamps can be made, for example, in the form of pins on one of the flat cathode assemblies: and blind holes for the pins in an appropriate place on the plane of the adjacent cathode assembly or side wall -. Ur; the aforementioned clamps also provide a predetermined air gap between the cathodes of adjacent cathode assemblies. The side walls on the inner side in the upper part are equipped with grooves 15, which can be used to fasten the load consumer board. On the cover 12 are plate spring

use to connect the board with the consumer loads. In the case of a new battery p: the electrode assemblies are filled with a predetermined amount of electrolyte 8 (aqueous solution of sodium chloride or alkali). Filling with electrolyte is carried out with the cover removed and the anodes removed, or through hole 14 on the battery cover, which also serves to exit the gases generated during battery operation. In case of overwork or when it is necessary to replace spent anodes, all anodes are easily removed with the cover. Replacing your anode is easily removed after removing the spring groove 7. When reused, all the anodes are simultaneously immersed in the electrolyte of the cathode assemblies when the cover is mounted on the battery.

The above description of the operation and operation of the claimed battery shows that this battery can be implemented in practice. Therefore, the claimed invention meets the criterion of industrial applicability.
