Design for solid cells

Abstract

The invention relates to a method for producing a solid cell, in particular a lithium-ion solid cell, having at least one cell layer (1) with a first conductor layer (2) and a second conductor layer (3) and at least one partition layer, wherein the first conductor layer (2) and the second conductor layer (3) are each electrically connected to a current discharge conductor (4, 5) and / or in each case one current discharge conductor (4, 5) is formed from the first conductor layer (2) and / or the second conductor layer (3). According to the invention, it is provided that the cell layer (1) has a plane of symmetry (SE) with an axis of symmetry (AA), wherein the plane of symmetry (SE) is constructed symmetrically in relation to the axis of symmetry (AA), and in that the current discharge conductors (4, 5) are arranged symmetrically in relation to the axis of symmetry (AA) and are routed out of the cell layer (1) on at least one side by means of the plane of symmetry (SE).

Description

technical field [0001] The invention relates to a method for producing a solid fuel cell according to the preamble of claim 1 and a solid fuel cell according to the preamble of the independent device claim. Background technique [0002] Solid fuel cells or solid fuel cells or solid state batteries are currently of particular interest not only for mobile applications but also for stationary applications. In these batteries, the liquid electrolyte is replaced by a solid-state electrolyte (Solid-State-Electrolyte). In this way, for example, the risk of thermal runaway / fire (thermal runaway) and explosion of the solid fuel cell can be reduced, and the safety and cycle life of the battery can be increased hereby. [0003] However, solid fuel cells, such as solid-state lithium-ion batteries, due to their internal structure and their operating principle, i.e. due to the deposition / deposition of lithium, have a higher charging and discharging capacity compared to known lithium-ion ...

AI Technical Summary

Problems solved by technology

[0007] However, in known solid fuel cells, the parallel or series connection is extremely complex and thus expensive to produce due to the geometry and construction of the cell layers or layer stacks and especially due to the arrangement of the current collectors.

Furthermore, the known connection variants also require a lot of installation space, which must also be increased in order to ensure an expansion or contraction of 10 to 40% of the cell layers or layer stacks within the solid fuel cell
