A battery cell includes a membrane configured to curve outwards when pressure inside the battery cell increases, thereby creating an electrically conductive connection between two poles. A conductor is arranged on an outside of the membrane and is connected to the battery cell such that the outward-curving membrane lifts the conductor from the membrane on one side such that the poles are electrically connected to one another via the conductor.

The present invention provides a method for manufacturing a battery which includes a granulation step (Step S1) of mixing at least an active material, a binder, and a solvent to form wet granulated particles, a deposition step (Step S2) of subjecting the wet granulated particles to a forming process to form an active material layer on a current collector, a rolling step (Step S3) of placing a separator on a surface of the active material layer and rolling the separator before the wet granulated particles on the current collector are dried, to obtain a laminated body in which the current collector, the active material layer, and the separator are stacked in this order and closely attached to each other, a drying step (Step S4) of drying the laminated body to provide an integrated laminated body, and a fabrication step (Step S5) of fabricating a battery using the integrated laminated body.

A battery housing part for a traction battery of an electric or hybrid vehicle. A first partial region of the battery housing part is composed of a plastic and at least one second partial region is composed of a material that is different therefrom. In this way, high degree of stiffness of the battery housing part can be achieved together with low weight. The second partial region that is composed of a material of a different type can be provided in a targeted manner where the at least one second partial region enables the greatest advantage in respect of the stiffness of the battery housing part. The use of a plastic for other partial regions of the battery housing part makes it possible to keep the weight of the battery housing part low.

A wiring module that is used in a battery assembly in which a columnar positive electrode and a columnar negative electrode of a plurality of batteries formed in a thin-type rectangular parallelepiped shape are arranged alternately. The wiring module includes a terminal pattern on a surface of an insulating resin substrate connected to the columnar positive electrode and the columnar negative electrode; a voltage detection wiring pattern on the surface connected to the terminal pattern; a fuse pattern on the surface interposed in the voltage detection wiring pattern; and an insulating resin layer that covers a peripheral portion of the terminal pattern, the voltage detection wiring pattern, and the fuse pattern are covered with the insulating resin layer A pair of through-holes, into which the columnar positive electrode and the columnar negative electrode are inserted, is formed in the terminal pattern and the insulating resin substrate.

An example retention method includes, among other things, resting opposing laterally outer regions of a battery array on a respective first and second rails that are disposed on an enclosure structure such that the battery array is spaced a distance from the enclosure structure. The method then includes securing, from at least one position between the laterally outer regions, the battery array relative to the enclosure structure. An example retention assembly includes, among other things, an enclosure, a first and a second rail, and a battery array having a first laterally outer region resting on the first rail and an opposing, second laterally outer region resting on the second rail. The battery array is secured relative to the enclosure at a position spaced from the first and second laterally outer regions to clamp the first and second laterally outer regions against the first and second rails.

Single, internally adjustable modular battery systems are provided, for handling power delivery from and to various power systems such as electric vehicles, photovoltaic systems, solar systems, grid-scale battery energy storage systems, home energy storage systems and power walls. Batteries comprise a main fast-charging lithium ion battery (FC), configured to deliver power to the electric vehicle, a supercapacitor-emulating fast-charging lithium ion battery (SCeFC), configured to receive power and deliver power to the FC and/or to the EV and to operate at high rates within a limited operation range of state of charge (SoC), respective module management systems, and a control unit. Both the FC and the SCeFC have anodes based on the same anode active material and the control unit is configured to manage the FC and the SCeFC and manage power delivery to and from the power system(s), to optimize the operation of the FC.

A battery is provided. The battery includes a power generation element having a through hole; and a cylindrical can housing the power generation element and having at least one thin wall part on a circumferential surface of the cylindrical can. A ratio of a hole diameter of the through hole to an outer diameter of the power generation element is 17% or less. The thin wall part is provided in one or both of regions in a range from 0% to 30% and a range from 70% to 100% from one end of the circumferential surface.

Disclosed herein is a pouch-shaped secondary battery including a micro-perforated electrode lead having adhesive properties that is capable of enabling a short circuit to occur in the pouch-shaped secondary battery using the adhesive properties of the micro-perforated electrode lead with respect to a pouch-shaped battery case in order to secure the safety of the pouch-shaped secondary battery when the pouch-shaped secondary battery swells due to gas generated in the pouch-shaped secondary battery while the pouch-shaped secondary battery is in an abnormal state or when the pouch-shaped secondary battery is overcharged. Current is prevented from flowing in the pouch-shaped secondary battery when the pouch-shaped secondary battery is overcharged or when the pouch-shaped secondary battery is in an abnormal state.
