Abstract: High-temperature storage battery with at least two or more storage cells of the alkali metal and chalcogen type, with each cell bounded by a metallic housing, and wherein a defined number of storage cells forming a module are combined. The housing of each storage cell is formed by at least two concentrically arranged housing elements, which are separated from each other by electrical insulation, and the storage cells of each module are arranged in a defined manner, and adjacent storage cells are connected to each other at least in some regions via their outer housing elements.

Abstract: Thermal insulation with at least one evacuated space, within which several layers of a non-metallic material are arranged. Between two respective successive layers, an intermediate layer serving as a spacer is arranged. The layers forming the insulating material consist preferably of mica paper. The intermediate layers are formed by layers of fiberglass fabric or mica powder. Glass or ceramic fiber paper may also be used for forming the intermediate layers.

Abstract: High-temperature battery with at least one electrochemical storage cell which is surrounded by thermal insulation as well as by feed and discharge lines for the cooling air. At least one module which can be inserted into the high-temperature battery, contains the storage cells. The module has a feedline for cooling air and a discharge for the cooling air which are arranged so that the cooling air can be introduced into the module against the force of gravity and discharged from the module with the force of gravity.

Abstract: High-temperature battery with at least one electrochemical storage cell of the alkali metal and chalcogen type and thermal insulation which surrounds the storage cell and is provided with feedthroughs for the electric conductors. Each of the electric conductors brought into the high-temperature battery consists of at least two subconductors which are connected to each other detachably and in an electrically conducting manner via at least one contact element. The contact element forming the contact point is arranged in the interior of the high-temperature battery.

Abstract: Electrochemical storage cell based on alkali metal and chalcogen comprising at least one anode space for the alkali metal anolyte and a cathode space for the chalcogen catholyte, with the anode space and the cathode space separated from each other by an alkali ion-conducting solid electrolyte wall and a metallic housing bounding the cell. The solid electrolyte wall has a plurality of spaced, outwardly extending hollow recesses, and at least one current collector disposed between each pair of adjacent recesses.

Abstract: An electrochemical battery for production of high outputs and efficiencies with high current densities comprising a plurality of cells, particularly metal-air cells each comprising a consumable electrode, and an air electrode spaced from the consumable electrode with electrolyte disposed in an electrolyte space and current take-off. The consumable electrode has a rod-shape made at least partially of a dense metal, the consumable electrode having a front face constituting a sole working surface projects sealed-off into the electrolyte space. An air electrode is spaced by the smallest distance parallel to the working surface of the consumable electrode, and an adjustable mounting for one of the electrodes maintains the spacing between the electrodes constant. The cells are arranged parallel to one another and connected in series, the air electrode and the consumable electrode of each of the cells being reversed with respect to the consumable electrode and the air electrode of the adjacent cell.

Abstract: A lead storage battery with positive and negative plates, the contact lugs of which respectively are connected with one another by lug bridges. The grid upper part of each plate grid is covered with an acid resistant synthetic material covering, which synthetic material covering surrounds the contact lugs acid-tight, the synthetic material covering being connected acid tight with the cell cover or one-piece composition case cover. The lug bridges are connected with one another outside of the acid space of the contact lugs.

Abstract: A device for production of high outputs and efficiencies with high current densities in an electrochemical system, particularly a metal - air cell, comprising a consumable electrode, an air electrode, an electrolyte disposed in an electrolyte space and current take-off. The consumable electrode has a rod-shape spacial form made at least partially of compact metal, the consumable electrode having a front face constituting a sole working surface and projects sealed in the electrolyte space. An air electrode is spaced by the smallest distance parallel to the working surface of the consumable electrode, and an adjustable mounting for one of the electrodes, particularly the consumable electrode, uniformly maintains the spacing between the electrodes in the axial direction.
