| titleOfInvention | Production of a separator, especially for lithium ion batteries |
| abstract | The present invention relates to a process for producing separators, especially electrical separators, and to the separators themselves. An electrical separator is a separator used in batteries and other arrangements in which electrodes have to be separated from each other while maintaining ion conductivity for example. The separator is preferably a thin porous insulating material possessing high ion permeability, good mechanical strength and long-term stability to the chemicals and solvents used in the system, for example, in the electrolyte of the battery. In batteries, the separator should fully electrically insulate the cathode from the anode. Moreover, the separator has to be permanently elastic and to follow movements in the system, for example, in the electrode pack in the course of charging and discharging. This object is achieved by the process of the present invention in which a substrate is provided with a porous ceramic coating, the coating operation being controlled so as to guide the substrate at a maximum tension of 10 N/cm in the longitudinal direction. This measure ensures that the coating has a distinctly higher durability than in the case of separators which were produced by conventional processes, since any deformation, especially elastic or plastic deformation, and any shrinkage of the substrate material are very substantially avoided. |
