Description

The utility model relates to energy and can be used to produce electrical energy.

A known battery containing a housing, a block of electrodes with separators in the form of rods located at a distance equal to the thickness of the electrodes and connected at the top by a bar, and an electrolyte (SU 1480692, H01M 2/18, publ. 27.12.1995).

The disadvantage of this battery is insufficient capacity.

Closest to the claimed one is a battery containing a sealed housing, positive and negative electrodes, an aqueous solution of metal chloride as an electrolyte, gas chambers separated by an elastic element in the form of a siphon, current outputs (RU 2056676, H01M 8/08, publ. 20.03.1996) .

The disadvantage of such a battery is also the lack of capacity.

The utility model solves the problem of increasing the capacity of the device for generating electrical energy.

This is achieved by the fact that in a device for producing electrical energy containing a housing, positive and negative electrodes, an aqueous solution of metal chloride as an electrolyte, current leads, according to a utility model, the electrodes have an adsorbent shell, positive electrodes are connected in series in series, negative electrodes are connected in series in another row, the rows are located along the walls of the body, positive opposite to the negative, and the number of rows of each type can be more than one, but as e electrolyte is an aqueous solution of the salts NaCl, KCl, MgCl ₂ at a concentration of 4-200 mg / l.

When the concentration of salts of NaCl, KCl, MgCl ₂ in the water-salt solution is less than 4 mg / l, the device will not be charged.

When the concentration of salts of NaCl, KCl, MgCl ₂ in a water-salt solution of more than 200 mg / l will increase the evolution of gases on the electrodes similar to the boiling process.

The serial connection of the electrodes of each type in the corresponding rows and the arrangement of the rows along the opposite walls of the housing — positive versus negative — allows the design to be compact, and due to the number of electrodes to increase the capacity of the device.

In the process of charging on the negative and positive electrodes, hydrogen and chlorine gases are released, respectively, absorbed by the shell consisting of an adsorbent, for example, activated carbon powder.

The utility model is illustrated by drawings.

In FIG. 1 shows a device in section, in FIG. 2 - the device in plan, in FIG. 3 - option for using the device in natural conditions.

The device comprises a housing 1 filled with electrolyte 2, electrodes 3 having a shell of activated carbon 4. The electrodes are connected to a direct current source 5. The positive electrodes are arranged in at least one row. Negative electrodes are also arranged in at least one row. A row (rows) of positive electrodes are located along the wall of the housing 1, and a row (rows) of negative electrodes is located opposite the row of positive electrodes along the opposite wall of the housing 1.

The device operates as follows.

When you turn on the DC source 5, the device is charging. In this case, the shell 4 of activated carbon at the electrodes attached to the negative terminal of the DC source is saturated with hydrogen, and the shell 4 of activated carbon at the electrodes attached to the positive terminal is saturated with chlorine.

When you turn off the DC source 5, the device is discharged. When discharging, reverse processes occur. When the electrodes 3 are shorted to an external load, an electric current will flow to the consumer, since a potential difference arises between them.

The device can be used to accumulate electric energy in natural conditions, when the salt water of natural reservoirs - salt lakes, bays of the seas and oceans is used as an electrolyte, and, for example, solar panels are used as a current source. In the sunniest summer period of time, when the solar power station is operating from 1 to 3 months (720-2160 hours), devices for accumulating electricity located in salt lakes, bays of the seas and oceans are charged. Given the size of the water area, the capacity of the devices is quite large. In the winter period of time there is a discharge of devices when an electric current is sent to power consumers. Throughout the year, these processes are cyclically repeated.

The estimated capacity indicators of electric energy storage devices located in natural water bodies with salt water are shown in the table.
