- a variety of materials can be used for the matrix (A). You can work with solvent-free or solvent-based systems. Suitable solvent-free systems are, for example, crosslinkable, liquid or pasty resin systems. Examples of these are resins made from crosslinkable addition polymers or condensation resins. For example, pre-condensates of phenoplasts (novolaks) or aminoplasts can be used which, after the pasty mass has been shaped, are finally crosslinked to form an electrochemical layer composite. Further examples are unsaturated polyesters which can be crosslinked by graft copolymerization with styrene, by bifunctional ones

- Natural or synthetic rubbers for example, can be used as polymers with a pure carbon main chain. Fluorinated ones are particularly preferred Hydrocarbon polymers such as Teflon, polyvinylidene fluoride (on PVDF) or polyvinyl chloride, since this enables particularly good water-repellent properties to be achieved with the films or layers formed from the pasty mass. This gives the electrochemical components produced in this way particularly good long-term stability.
- polystyrene or polyurethane examples are polystyrene or polyurethane.
- copolymers are copolymers of Teflon and amorphous fluoropolymer and polyvinylidene fluoride / hexafluoropropylene (commercially available as Kynarflex).

- Solvents or swelling agents for the abovementioned polymers are known to the person skilled in the art.
- Plasticizers or “plasticizers” are to be understood here as substances whose molecules are bound to the plastic molecules by secondary valences (Van der Waals forces). By doing so, you reduce the
- plasticizers for the respective plastic groups. They must be compatible with the plastic in which they are to be incorporated. Common plasticizers are high-boiling esters of phthalic acid or phosphoric acid, for example dibutyl phthalate or dioctyphthalate. Also suitable are, for example, ethylene carbonate, propylene carbonate, dimethoxyethane, dimethyl carbonate, diethyl carbonate, butyrolactone, ethyl methyl sulfone, polyethylene glycol, tetraglyme, 1,3-dioxolane or S, S-dialkyldithiocarbonate.
- the plasticizer can then be detached from the pasty mass with a suitable solvent or by evaporation (for example under vacuum and / or elevated temperatures).

This improves the electrochemical stability of the charged accumulator.

- parts by weight of 20 to 80% by weight of amorphous carbon, based on the electrochemically activatable component are advantageous.
- the mass is provided for a positive electrode, the lubricating effect of the carbon is to be mentioned as an advantageous property, which improves the mechanical flexibility of a layer produced from the pasty mass.
- the mass is provided for a negative electrode, the electrochemical stability and the electronic conductivity are additionally improved, as already described above.

- An example of this is the combination of copper plus lithium sulfate.
- the electrode material (B) is a metal that does not react with lithium and also contains a lithium salt.
- the matrix (A) in this variant is produced from a combination of plastic with a plasticizer, which is then removed from the pasty mass again.
- the cavities formed should not be used when the electrochemically activatable layers are subsequently laminated under pressure or the like. getting closed; rather, it is important to ensure that they remain open.
- a lithium salt in the adjacent electrolyte layer such composite electrode has the 'property of reversibly switched lithium in the resulting cavities, and can expand. It has the advantages of an intercalation electrode, but avoids its disadvantages (e.g. volume expansion) and has excellent electrical properties due to the large inner surface.
- Nickel is an example of a metal that does not react with lithium.
- the solid substance (B) is an electrode material or an electrolyte material, it can consist of a lithium ion conductor and one or more further ion conductors (eg for Li, Cu, .Ag, Mg, F, Cl, H). Electrodes and electrolyte layers produced in this way have particularly favorable electrochemical properties such as capacity, energy density, mechanical and electrochemical stability.
- the mass to be introduced into the fabric can additionally contain a second solid ion, electron and / or 1 a mixed conductor (C).
- a second solid ion, electron and / or 1 a mixed conductor (C) This can be worked into the matrix in different ways. If it is an ion conductor which is soluble in a solvent - for example that in which the matrix material (A) is also soluble - the mass can be produced by the solvent for the matrix material containing this second ion conductor.
- the vapor pressure of the solvent must be so high that it can be expelled at a later stage (e.g. after intimately mixing the constituents of the mass, even if it has a pasty consistency without the presence of the solvent, or after generating the Layer or foil).
- plasticizer which is also soluble in the solvent and which can then optionally be removed again using the solvent mentioned.
- This embodiment of the invention can also be accomplished with such conductors (C) which have a relatively poor conductivity (in particular ion conductivity if this property is to be present).
- an ion, electron or mixed conductor (C) can be selected, which is soluble in the selected plasticizer for the system.
- the plasticizer should have a relatively low vapor pressure.

- calender coating with two or three nips, in which in addition to the pasty mass, the carrier web comes in, or doubling (bonding under pressure and back pressure of preferably heated rollers).
- a pressing process during the bonding (lamination) of the individual layers can often be desired, not only for better bonding (and thus achieving better conductivity) of the individual layers, but also, for example, in order to eliminate any cavities that may be present in the individual layers for example, as described above, by washing plasticizers or the like. Common techniques can be used for this. Cold pressing (at temperatures below 60 ° C.) can advantageously be carried out, provided the materials used allow this. This ensures particularly good contact between the individual layers.
- the layers produced as described can be impregnated with an electrolyte solution (e.g. a lithium salt dissolved in an organic solvent such as propyl carbonate and / or ethyl carbonate or the like) before or after lamination.

Due to the fabric structure, this adheres particularly well in contrast to application to metal strips.
- Example 1 To produce a positive electrode, 2 g of PVDF-HFP are combined with 1 g of ethylene carbonate and 100 g of acetone. Then 14 g of LiCo0 2 and 3 g of conductive carbon black are added in the form of fine powders. These constituents are then intimately mixed with one another by vigorous stirring. A commercially available aluminum-coated fabric is then dipped into this paste. The fabric thickness was 150 ⁇ m. After the tissue has been pulled out of the paste in a controlled manner, it is filled with paste. The filled tissue is then dried and dipped again. The desired layer thickness can be set by alternately drying and dipping. A stable and highly flexible film was obtained which was used as a positive electrode in a lithium accumulator.
