ELECTROCHEMICAL CELL WITH WELD POINTS CONNECTIONS AND ENERGY STORAGE ASSEMBLY

摘要

The invention relates to an electrochemical cell (2) with a pair of electrodes (A, K) arranged as a stack of flat electrode films (A1 to An, K1 to Kn) separated by a separator film, wherein: electrode films (A1 to An, K1 to Kn) of each electrode (A, K) are electrically connected with each other through inner electrode conductors (4.A, 4.K); the inner electrode conductors (4.A, 4.K) of the different electrodes (A, K) are arranged on opposite sides of the electrochemical cell (2) in electrode material-free area of the electrode films (A1 to An, K1 to Kn); each inner electrode conductor (4.A, 4.K) is connected with the respective electrode films (A1 to An, K1 to Kn) through a predetermined number of weld points (5.1 to 5.z) in the electrode material -free area of the respective electrode (A, K); each inner electrode conductor (4.A, 4.K) comprises a predetermined number of openings (6.1 to 6.m) in which coupling elements are set to connect the inner electrode conductor (4.A, 4.K) with an outward electrode conductor (7.A, 7.K) for the respective electrode (A, K).
