Solid-electrolyte battery, particularly for the storage of electrical energy

DETAILED DESCRIPTION The invention, then, addresses the problem of developing a solid-electrolyte battery of the aforementioned type which avoids the indicated disadvantages, in particular, combining high energy density and high specific output while retaining long lifetime and low material cost.
Further, the solid-electrolyte battery is to be simple in construction and therefore easy to make, as well as reliable enough for all fields of application.
The solution of the problem consists, in accordance with the invention, of making the solid-electrolyte battery in the form of a multiplicity of parallel-connected, tubular anode and cathode spaces bounded by the solid electrolyte and alternatingly arranged in close proximity to one another so that each electrode space presents reaction surfaces simultaneously to at least two neighboring electrode spaces of the opposite polarity.
By splitting up the anode and cathode space into a multiplicity of parallel-connected electrode spaces, their reaction areas are considerably increased.
Since here the electrode spaces are completely surrounded by solid electrolyte, no problems about additional materials arise.
Each of the electrode spaces has at least two neighboring electrode spaces of opposite polarity to its own, and the specific output is therefore additionally increased.
The electrode spaces are packed close together and their inner cross section is made as small as possible compared with their surface, but not so small as to interfere with the supply of reactants or removal of reaction products or with current input or output.
A cross-sectional area of the electrode spaces of preferably 10 mm.
sup.
2 and a length of these spaces of about 100 mm should not be exceeded in sodium-sulfur batteries, for example.
Since all electrode spaces are surrounded by solid electrolyte, no special external sealing of the battery is usually necessary.
The solid electrolytes of the application can consist of any materials and according to the type and/or conditions of use of the battery can be formed as ceramic, organic or semi-solid electrolytes
