Description

one

An electric battery is known that contains heterogeneous electrodes placed in a housing separated by tubular separators.

This battery has the following disadvantages.

A battery, such as an alkaline battery, cannot be operated at high temperatures for extended periods. To partially eliminate this deficiency in alkaline batteries, it is recommended to use a composite electrolyte. At low temperatures, battery capacity decreases.

In case of battery batteries, a rise in temperature causes irreversible sulfation of the electrodes, leading to premature battery failure due to the destruction of the positive electrodes and separators. At low temperatures, capacitance decreases. Therefore, they try in the summer time to cool the batteries in various ways. In the cold season, on the contrary, it becomes necessary to heat the electrolyte of batteries.

In the summer, ice, cold water baths, air cooling, and electrolyte heating, various shelters, and insulation are used for cooling and heating in the summer. The use of special heaters or

coolers complicates the design of the battery.

In order to simplify the design, the separators of the proposed battery are connected

consistently and at free ends provided with fittings, derived on the outer surface of the housing.

FIG. I shows the proposed battery; FIG. 2 is a section along L-A in FIG. one.

The battery consists of a housing /, in which are placed the opposite electrodes 2 and 3, separated by tubular separators 4, the free ends 5 of which are provided with fittings 6. The separators are connected in series. The fitting 6 is brought to the outer surface of the housing. One fitting serves to supply water, the second - for its removal. In this way, the separators also perform the functions of a heat exchanger, cooling or heating the electrolyte of the battery.

Water circulates inside the separator. As a separator, glass tubes or tubes of any other acid-resistant or alkali-resistant dielectric with sufficient thermal conductivity can be used. When using this design in stationary batteries, water is supplied to the fittings. When the temperature rises, water is turned on, and

electrolyte. The battery can constantly

work with water cooling on. To warm the electrolyte, warm water must be turned on. The material of the separators must be heat resistant in this case.

If such a device is, for example, in an alkaline battery used on battery loaders, then daily charging of the battery leads to charging of the electrolyte cooling water.

Subject invention

An electric battery containing electrodes of the opposite type, separated by tubular separators, is characterized in that, in order to simplify the design, the separators are connected in series and equipped with fittings on the outer ends of the body on the free ends.
