Abstract
Official abstract text for this publication.
A method for producing an electrode for a storage device for storing electrical energy is provided. A main body of the electrode is coated with at least one active material for storing electrical energy. A mixture, which includes the active material and fibers, is provided. The main body is coated with the mixture, which is free of a solvent that receives the fibers and escapes at least predominantly from the mixture after coating of the main body. By coating the main body with the mixture, a coating which includes the active material and the fibers is formed on the main body from the mixture.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for producing an electrode for a storage device for storing electrical energy, in which a main body of the electrode is coated with at least one active material for storing electrical energy, the method comprising: providing a mixture comprising the active material and fibers; and coating the main body with the mixture, which is free of a solvent that takes up the fibers and that at least predominantly escapes from the mixture after coating the main body, wherein as a result of coating the main body with the mixture, a coating comprising the active material and the fibers is formed on the main body from the mixture, wherein the main body is coated with the mixture by extrusion. 2 . The method according to claim 1 , wherein after coating the main body with the mixture, the coating is brought into contact with an electrolyte, which is at least partly taken up by the fibers. 3 . The method according to claim 2 , wherein the electrolyte is a liquid. 4 . The method according to claim 2 , wherein the electrolyte is at least partly absorbed by the fibers. 5 . The method according to claim 1 , wherein before and after coating the main body with the mixture, a process of coating the main body with a solvent does not occur. 6 . The method according to claim 1 , wherein cellulose fibers are used as the fibers. 7 . The method according to claim 1 , wherein the main body is coated with the mixture by lamination. 8 . The method according to claim 1 , wherein the fibers are electrically conductive. 9 . The method according to claim 1 , wherein the fibers are formed from a non-combustible material or a material of low flammability. 10 . The method according to claim 1 , wherein the mixture further comprises a binder. 11 . The method of claim 1 , further comprising using the electrode for an electrical pole of a storage device for storing electrical energy. 12 . The method of claim 11 , wherein the electrical pole is positive.
