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.

Method for producing an electrode for a storage device for storing electrical energy, use of an electrode of this kind, and electrode

A cell for an electrical energy store is provided, including a cell housing within which there is arranged an electrode and on the outer side of which there is arranged a terminal which is galvanically connected to the electrode, wherein an electrical securing element is connected in a current path between the terminal and the electrode for the purposes of galvanic separation of the electrode and of the terminal. The cell is characterized by having the securing element arranged outside the cell housing. In this way, it is possible in a simple manner for the state of charge of the cell to be checked, and also for the cell to be discharged, from the outside.

Cell for an electrical energy store

In order to allow for a compact configuration of a battery with an increased energy density/volume ratio together with low production costs, the invention specifies a battery electrode and a method for producing same, wherein an arrester region is arranged on a collector substrate such that it is predominantly surrounded by a coating film.

Battery electrode and a method for producing same

In order to allow for maximum freedom of design in the selection of an electrode or battery shape, a compact configuration and low production costs, the invention specifies a battery electrode and a method for producing same, wherein a collector substrate is coated with a coating film and at least one arrester region is produced thereon by removing the coating film by means of laser ablation.
