An electronic component for a cell-contacting system with cell connectors is used for power contacting of battery cells of a battery. The component contains a circuit board of a measurement and/or management assembly for the battery, and has plug receptacles for connection to the cell connectors, a support frame with receptacle for the circuit board, electrical connection elements for connection of the circuit board and the cell connectors to plug contacts, embedded in the support frame, for the plug receptacles. The circuit board is insertable into the receptacle by plugging the plug receptacles with the plug contacts and has a communication interface. A cell-contacting system with cell connectors contains at least one electronic component. When producing a cell-contacting system, the electrical connection elements are firstly connected to the cell connectors and the circuit board is then inserted into the receptacle.

A battery module 1 includes an array body including a plurality of battery cells held by cell holders and arranged along a predetermined array direction, and elastic members disposed between adjacent battery cells, and a restraint member applying a restraining load to the array body in the array direction. The cell holder has a protrusion protruding in the array direction, and a compression amount of the elastic member between the battery cells is regulated by the protrusion abutting on a cell holder of an adjacent battery cell.

A battery pack includes a pouch cell having electrode tabs extending therefrom, each of the tabs defining perforations, a bus bar in contact with the tabs, and respective agglomerations of mechanically bound solid metal particles each filling one of the perforations to mechanically bind and electrically connect the tabs to the bus bar.

Certain embodiments of the invention relate to the design of three-dimensional battery cells and their incorporation into battery modules and battery packs. The present invention may be particularly advantageous when incorporated into large battery packs, for example, those used in electric vehicles. The unique architecture of the battery cells of certain embodiments of the invention provides improved thermal performance with significant impact on cycle and calendar life when incorporated into a battery pack. Substantially higher pack energy density for a given cell energy density is provided when compared to a conventional cell. Battery cells can be strung together to form modules and packs with whatever series/parallel arrangement required for a particular application. Cooling, if needed, can be incorporated at the module level rather than the individual die level, as is the case with conventional architectures, dramatically reducing the cost of the system.

The present application discloses a secondary battery, a battery module, and a device using the secondary battery as a power source. The secondary battery includes: a casing; an electrode assembly disposed in the casing; a cap assembly; and a current collecting member including an adapting piece and a connecting component provided separately and connected with each other; the adapting piece connected with the electrode terminal of the cap assembly and including a guiding section; the connecting component including a current collecting section to be connected with the guiding section and a tab connecting section to be connected with the electrode assembly; and the connecting component has a rigidity less than that of the guiding section, so that deformation of the guiding section toward the electrode assembly can be reduced when a portion of the connecting component connected with the electrode assembly is bent with respect to the length direction.
