Cartridge for battery cell and battery module comprising same

Abstract

A cartridge for a battery cell according to the present invention comprises: an upper cooling plate and a lower cooling plate which are formed in a plate shape and spaced apart from each other in a face-to-face form so as to form a cooling flow passage therein; a main frame which is formed to surround the outer periphery of the upper cooling plate and the outer periphery of the lower cooling plate, and is configured such that the battery cell is fixed in an upper portion and a lower portion thereof; and a support which is positioned in the cooling flow passage, and has one or more supporting ribs formed protruding in at least one direction of the upper and the lower portions of the support so as to support the upper cooling plate and the lower cooling plate.

Description

technical field [0001] The present disclosure relates to a battery, and more particularly, to a case for a battery cell configured in a battery cell having a plurality of battery cells and a battery module including the case. Used for battery modules. [0002] This application claims priority from Korean Patent Application No. 10-2017-0096868 filed in Korea on Jul. 31, 2017, the disclosure of which is incorporated herein by reference. Background technique [0003] Currently commercially available battery cells include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium battery cells. Among these battery cells, lithium battery cells have attracted much attention because lithium batteries have almost no memory effect compared to nickel-based battery cells, and also have very low self-discharge rate and high energy density. [0004] Lithium battery cells use lithium-based oxides and carbonaceous materials as positive electrode active m...

Problems solved by technology

However, in conventional battery modules, the cooling channels are not stably fixed around the cooling plate

In particular, aluminum materials are widely used as cooling plates, but cooling plates made of aluminum are prone to deformation such as crushing or twisting during injection molding of stack frames, coupling to frames, or use of battery modules

[0012] The deformation of the cooling plate can reduce or block the cooling channel, thereby disturbing the flow of external air through the cooling channel, thereby greatly reducing the cooling efficiency of the battery cells through the cooling plate

A configuration has been proposed in which a bead is formed on the cooling plate to prevent deformation of the cooling plate, but in this case, the bead may be deformed, so that the cooling flow path cannot be stably ensured.
