Abstract
The invention relates to a roller (1) for use in a dry coating process to produce electrodes, comprising: a roller core (3) consisting of a core material; a roller shell (4) consisting of a shell material, the roller shell surrounding the roller core at least in sections; the shell material having a greater hardness than the core material; and the roller core including a device for tempering the roller shell.
Claims25
A roller for use in a dry coating process to produce electrodes, comprising:
- a roller core consisting of a core material;
- a roller shell consisting of a shell material, the roller shell surrounding the roller core at least in sections;
- wherein the shell material has a greater hardness than the core material;
- and wherein the roller core has a device for tempering the roller shell.
A roller for use in a dry coating process to produce electrodes, comprising:
- a roller core consisting of a core material;
- a roller shell consisting of a shell material, the roller shell surrounding the roller core at least in sections;
- wherein the shell material has a greater hardness than the core material;
- wherein the roller shell and the roller core are designed as separate components and the essentially tubular roller shell is attached to the roller core in a force-fit and/or form-fit manner;
- and wherein the roller shell consists of a curable steel, such as a cold work steel, and is through-hardened on its surface at least to a depth of at least 5 mm.
A roller for use in a dry coating process to produce electrodes, comprising:
- a roller core consisting of a core material;
- a roller shell) consisting of a shell material, wherein the roller shell surrounds the roller core at least in sections;
- and wherein the roller core has a device for tempering the roller shell;
- wherein the device for tempering the roller shell has a plurality of independently segmented tempering zones in the axial direction (X) of the roller, wherein individual temperatures can be set in the individual tempering zones.
A roller assembly for use in a dry coating process for producing electrodes, comprising two rollers forming a roller gap between them, of which at least one roller is designed as a roller of any one of the preceding claims,
- and further comprising at least two detection devices spaced apart orthogonally to the conveying direction of the electrode for detecting the thickness of the electrode produced in the roller gap,
- wherein the roller assembly also includes a control device which is designed to compare the at least two detected actual thicknesses with a target thickness and, when a deviation of one of the actual thicknesses from the target thickness is detected, the tempering zone assigned to the respective detection device is actuated by the control device in such a way that the respective actual thickness is brought closer to the target thickness.
A method of manufacturing an electrode, comprising the steps of:
- contacting an electrode precursor material with a roller, the roller including:
- a roller core consisting of a core material;
- a roller shell consisting of a shell material, the roller shell surrounding the roller core at least in sections;
- wherein the roller material has a greater hardness than the core material;
- and wherein the roller core has a tempering device for tempering the roller shell.
A method of manufacturing an electrode, comprising the steps of:
- by means of a roller assembly, which has two rollers forming a roller gap between them and at least two detection devices for detecting a thickness:
- bringing an electrode precursor material into contact with the roller assembly;
- detecting the thickness of an electrode formed in the roller gap with at least one of the detection devices;
- and adjusting the temperature of at least one of the rollers based on the detected electrode thickness.
An electrochemical laminate comprising at least one electrode layer formed by calendering an electrode precursor material with a roller comprising:
- a roller core consisting of a core material;
- a roller shell consisting of a shell material, the roller shell surrounding the roller core at least in sections;
- wherein the shell material has a greater hardness than the core material;
- and wherein the roller core has a device for tempering the roller shell.
