Abstract:
1. A battery comprising a plurality of electrochemical cells connected in series or parallel; each electrochemical cell having a length and comprises a series of primary laminates each including a negative electrode, a positive electrode, an electrolyte interposed between the negative and positive electrodes, a positive current collector extending from one side of the primary laminates and a negative current collector extending from an opposite side of the primary laminates; each electrochemical cell having a positive current collecting terminal connecting the positive current collectors together and a negative current collecting terminal connecting the negative current collectors together; the positive and negative current collecting terminals extending the entire length of the electrochemical cell, each positive and negative current collecting terminals having a folded extension arm for electrically connecting two adjacent electrochemical cells together either in series or parallel, a layer of PTC material being spread directly onto surfaces of the folded extension arm of adjacent positive and/or negative current collecting terminals over the entire length of the folded extension arm and being an integral part of an electrical connection between two adjacent electrochemical cells for opening and closing the electrical connection between the two adjacent electrochemical cells at a predetermined temperature.
