摘要:
Motor vehicle battery modules having an energy content of at least 5 kWh for use as energy storage for electric cars. Such a battery module includes multiple individual batteries, each of which has at least one housing and at least one galvanic cell disposed within the housing. The battery module further includes a joining device, by which the individual batteries are assembled to form a battery module that can be handled as a whole. The battery module has, on its outside, a spray-applied protective layer that includes a wax and surrounds at least sections of the battery module.

Provided is a surface-treated steel sheet for battery containers (100) that is obtained in such a manner that after iron-nickel alloy plating is performed on a steel sheet (10), a thermal treatment is performed and is characterized in that an outermost layer is an iron-nickel alloy layer (20), and the iron-nickel alloy layer (20) has an average crystal size of 1 to 8 μm at the outermost surface thereof. The present invention makes it possible to provide the surface-treated steel sheet for battery containers that can suppress the elution of iron inside the battery when being used for a battery container, whereby the service life of the battery can be extended and battery characteristics such as discharge characteristics is improved, and to provide a battery container and a battery that can be obtained using the surface-treated steel sheet for battery containers.

In a deformation detection method for a sealed-type rechargeable battery 1 in which an electrode group 22, which is formed by stacking a positive electrode 23 and a negative electrode 24 with a separator 25 interposed therebetween, is accommodated in a sealed outer casing 21, a polymer matrix layer 3 is attached to an outer surface of a wall portion 28a of the outer casing 21 that faces the electrode group 22 in a thickness direction of the positive electrode 23 and the negative electrode 24 or in a direction perpendicular to the thickness direction. The polymer matrix layer 3 contains a filler that is dispersed therein and that changes an external field in response to deformation of the polymer matrix layer 3. Change in the external field accompanying the deformation of the polymer matrix layer 3 is detected by a detection unit 4.

摘要:
A lithium ion (Li-ion) battery module includes a container with one or more partitions that define compartments within the container. Each of the compartments is configured to receive and hold a prismatic Li-ion electrochemical cell element, and a cover is configured to be disposed over the container to close the compartments. The container includes a polymer blend including a base polymer and one or more additives blended into the base polymer. The base polymer is electrically nonconductive and the one or more additives are configured to increase a thermal conductivity of the container to promote transfer of heat generated from the electrochemical cell elements through the container.

The present invention relates to an EMF-screened plastic-organic sheet hybrid structural component, preferably a battery housing, and to its use in motor vehicles, preferably in electrically powered motor vehicles or hybrid motor vehicles, the abbreviation EMF meaning electromagnetic field(s).
摘要:
A thin sheet or film excellent in flame retardancy and light-blocking properties is provided. A battery pack case and others with high flame retardancy are each molded from this thin film. A thin sheet or film Including a specific phosphorus-containing flame retardant in a polycarbonate resin is excellent in thickness accuracy, flame retardancy and appearance. A thin sheet or film excellent in flame retardancy and also having a thickness of 0.01 to 0.25 mm was formed when controlling its thickness uniformly during sheet or film molding. Further, upon addition of carbon black, the resulting sheet or film was found to have good light-blocking properties and higher flame retardancy. Moreover, when used as a film packaging material for battery packs, the sheet or film of the present invention was found to be excellent in film strength and ultrasonic weldability.
摘要:
The present disclosure provides a high heat radiation composite material including a hybrid filler comprising expanded graphite filled with expandable polymeric beads, and a fabrication method thereof. In the method, a dispersion solution is prepared by dispersing expandable polymeric beads in ethanol. Expanded graphite is immersed in the dispersion solution, and heat-treated to remove ethanol, thereby producing the hybrid filler. The hybrid filler is dispersed into the matrix polymer via an extrusion/injection process, thereby producing the composite material.
