摘要： A battery has: an electrode body; positive and negative electrode foils provided at surfaces of the electrode body; a metal exterior body pair formed from a positive electrode metal exterior body that contacts the positive electrode foil and a negative electrode metal exterior body that contacts the negative electrode foil; and resins that fix the electrode body and metal exterior body pair. Outer surfaces of the metal exterior body pair are exposed to enable electrical connection with an exterior. At least one of the positive or negative electrode metal exterior bodies is shaped as a box having a bottom plate that is quadrilateral and four side plates that each share one side with the bottom plate, and accommodates the electrode body at an inner side of the box shape. The positive and negative electrode metal exterior bodies and side surfaces of the electrode body are respectively insulated by the resins.

摘要： A traction battery device for an at least partially electrically driven motor vehicle includes at least one traction battery with at least one battery housing for housing battery modules and/or battery cells and at least one extinguishing apparatus for automatically carrying out an extinguishing process in an extinguishing situation. An extinguishing agent can be introduced into the battery housing with the extinguishing apparatus via at least one feed device. In this context, the extinguishing apparatus has at least one extinguishing-agent-generating device which, in the case of an extinguishing situation, is suitable for combining, and is designed to combine, at least two spatially separate extinguishing agent components in a controlled fashion and to mix them to form an extinguishing agent which can be extinguished and which can be introduced into the battery housing via the feed device.
