Embodiments of the present application provide a battery, a power consumption apparatus, and a method and apparatus for producing a battery. The battery includes: a battery cell, provided with a pressure relief mechanism, the pressure relief mechanism being configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; a bus component, configured to be electrically connected to the battery cell; an electrical cavity, configured to accommodate the battery cell and the bus component; a collecting cavity, configured to collect emissions from the battery cell when the pressure relief mechanism is actuated; and a sealing structure, disposed in an airflow path formed between the pressure relief mechanism and a wall of the electrical cavity and configured to prevent the emissions from reaching the bus component when the pressure relief mechanism is actuated.

Vented cells are held in a cell holder, which is also vented, to provide an escape path for gases that may be produced by failing or overloaded cells. The escape path leads to the outside of the cell holder, which is mounted in an enclosure forming the battery pack. The enclosure is also vented, via a pressure-relief valve, which allows for the escape of hot cell gases to the surrounding air. A cell holder is made up of a top tray, an intermediate tray and a frame. A venting path is formed between the top and intermediate trays.

An assembly for a traction battery of a motor vehicle includes a battery module having a cell composite formed by a plurality of battery cells, wherein degassing regions of the battery cells are located on an upper side of the cell composite for letting out a hot gas from a cell housing of the battery cells; a battery component arranged in a vertical direction above the battery module, such that the upper side of the cell composite is facing an underside of the battery component; and a protective unit having a sheet-metal-type protective region for protecting the battery component from the hot gas and a frame-type support region connected to the protective region. The battery component is secured to the support region and the protective region is arranged between the underside of the battery component and the upper side of the cell composite.

Embodiments of the present application are provided with a box of a battery, a battery, a power consumption device, and a method and device for producing a battery. The box of the battery includes: an electrical chamber; a thermal management component; and a collection chamber, configured to collect emissions from the battery cell provided with the pressure relief mechanism when the pressure relief mechanism is actuated; wherein the thermal management component is configured to isolate the electrical chamber from the collection chamber, a pressure relief region is disposed on the thermal management component, and the emissions collected by the collection chamber is discharged through the pressure relief region. According to the technical solutions of the embodiments of the present application, the safety of the battery can be enhanced.

An energy module for a powered unit includes: a plurality of cells; a pair of current collector strips; and a plurality of rivets. The plurality of rivets are configured to electrically connect the plurality of cells to the pair of current collector strips. Each cell of the plurality of cells consists of two terminals. The pair of current collector strips are mounted on the two terminals of each cell of the plurality of cells using the plurality of rivets. An elastic member based electrical connector assembly, along with a rivet from the plurality of rivets, is connected to at least one terminal of each cell of the plurality of cells for establishing an electrical connection between the at least one terminal and a current collector strip from the pair of current collector strips.

The present invention relates to a pouch-shaped battery cell including a battery case made of a laminate sheet, an electrode assembly received in the battery case, the electrode assembly having an electrode tab protruding therefrom, an electrode lead electrically connected to the electrode tab, the electrode lead extending outwards from the battery case, and a gas discharge portion located in the electrode lead, wherein it is possible to prevent the internal pressure of the pouch-shaped battery cell from being increased to a predetermined level or more.

A housing for a button cell battery includes a top, a can and a grommet. The skirt of the can extends between a top panel and a free end, and includes a substantially vertical first section and an outwardly tapered second section. The first section extends from the top panel of the can. The second section extends from the first section. Upon assembly of the housing, a flow path is defined between an outer surface of the skirt of the grommet and the inner surface of the skirt of the can. The flow path allows air to escape during the assembly, thus minimizing the risk of gas being entrapped within the interior of the housing of the finished cell battery.
