A lithium metal polymer battery comprising a rigid casing and at least one electrochemical cell; the battery assembled without an active mechanical pressure system.

Pressurized lithium metal polymer battery

An electrochemical cell battery having current collecting terminals acting as security device. 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.

Current collecting terminal with PTC layer for electrochemical cells

A battery pack for an electric or hybrid vehicle having battery connectors for connecting batteries in series and a battery connector are disclosed that reduces the risks of potential electric shocks during assembly, servicing and in emergency situation. The battery connector includes an interrupter having disconnect capabilities in the event of the vehicle being involved in a collision.

Battery pack with connecting device

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 Tof less than 180&#xb0; C. whereby if a temperature of an electrochemical cells rises above the fusion temperature Tof 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.
