SU48659A1 - Gas electric accumulator - Google Patents

Description

Gas elements are well known, as are gas batteries. The present invention also relates to the use of a gas galvanic circuit for the purpose of storing electrical energy using carbonaceous sorbents as active electrical materials, and consists in that in hermetically sealed gas spaces of the electrodes there are no powder electrolyte in contact with the electrolyte than absorption of excess gases during charging is achieved.

The drawing shows in section the form of the gas accumulator according to the invention.

Carbon tubes C and Z / j, which are the electrodes of the battery, are in the vessel b of the battery.

In its lower part, the carbon tubes have a gasket n, n of a mixture of amorphous carbon with asbestos fibers (for tube D3) and from a mixture of fine graphite powder with asbestos fibers (for tube Z / J.

Electrolyte-dilute sulfuric acid is added to the vessel.

The carbon tube, in turn, is wearing an electrically insulating jacket and, in order to achieve

unilateral gas evolution during charging (electrolysis).

The space above the electrolyte is filled with solid active sorbents — a fopfo carbon Cj and a fine graphite powder Q mixed with asbestos fibers.

The gases released during battery charging, as can be seen from the drawing, have the ability to penetrate to the sorbents from above, since the sorbents are enclosed in shells that are open only from the top and from the side of the carbon tubes in battery size).

For drainage and current supply, the battery is equipped with clips Aj and /.,.

The opportunity arose; The differential pressure in the accumulator is localized by thin elastic rubber bags RI and R. ,, communicating with the gas chambers through the mouth of the tubes. Pa. When the pressure in any gas chamber increases, the corresponding gas bag inflates and, thus, the pressure is balanced.

For the purposes of the initial removal of gases from sorbents and for filling; battery electrolyte is provided for hermetically closing tube T.

Gas chamber O contains oxygen, and chamber H contains hydrogen.

When the battery is charged, the gases emitted during the process of electrolysis of water — hydrogen and oxygen — are sorbed by electrode packing materials.

Molecular sorption of gases evolved during electrolysis is partly of stuffing materials, mainly powdery solid sorbents located in gas chambers.

During the process of discharge, the packing and powdered sorbents consume the absorbed gases to dissolve the self, and to depolarize 0.

Ultimately, water is formed and, thus, less losses, the battery returns to its original state.

Battery electrolyte can be both sulfuric acid and solutions of neutral salts of NaCl, ZnSO4, FeS04, KCl, and others.

The subject matter of the invention.
