Title:
CURRENT COLLECTING TERMINAL FOR ELECTROCHEMICAL CELLS
Document Type and Number:
WIPO Patent Application WO/2012/009803
Kind Code:
A8
Abstract:
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 having 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 having a folded extension arm for electrically connecting two adjacent electrochemical cells together. The current collecting terminals utilize layers of PTC materials strategically positioned whereby if a temperature of an electrochemical cell rises above the transition temperature of the layer of PTC material, electrical current is prevented to flow between electrochemical cells by the layer of PTC material.
