An electrochemical cell battery is disclosed having current collecting terminals acting as security device. The battery includes a plurality of electrochemical cells connected in series or parallel. Each electrochemical cell has a current collecting terminal connecting the positive current collectors together and a current collecting terminal connecting the negative current collectors together. The current collecting terminals each have a folded extension arm for electrically connecting two adjacent electrochemical cells together. The folded extension arms have a shape memory characteristic and are electrically connected together via a welding metal having a fusion temperature Tf of less than 180° C. whereby if a temperature of an electrochemical cells rises above the fusion temperature Tf of the welding metal, the welded connection melts and the folded extension arms of the current collecting terminals spring back to their initial shape thereby severing the electrical connection between the electrochemical cells.
