ENCASING FILM FOR A GALVANIC ELEMENT, ELECTROCHEMICAL STORE, ELECTROCHEMICAL STORAGE SYSTEM, FLEXIBLE FILM FOR AN ENCASING OF A GALVANIC ELEMENT, AND METHOD FOR DETERMINING A STATE VARIABLE OF AN ELECTROCHEMICAL STORE

摘要

An encasing film for a galvanic element has at least one force sensor for detecting an expansion state of the encasing film. The encasing film is produced from an elastic and electrically insulating material, e.g., plastic. The force sensor, which has a strain gauge, is situated on a surface of the encasing film.
