    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 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 T f of less than 180°C whereby if a temperature of an electrochemical cells rises above the fusion temperature T f 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.

    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.

    Abstract translation: 公开了一种电化学电池，其具有充当安全装置的集流端子。 电池包括串联或并联连接的多个电化学电池; 每个电化学电池具有将正极集电体连接在一起的集电端子和将负极集电体连接在一起的集电端子; 所述集电端子各自具有折叠的延伸臂，用于将两个相邻的电化学电池电连接在一起。 电流收集终端利用层叠的PTC材料，其策略性地定位，由此如果电化学电池的温度升高到PTC材料层的转变温度以上，则阻止电流通过PTC材料层在电化学电池之间流动。
