Abstract

The present invention relates to a battery module for preventing expansion of a battery cell and a method for manufacturing the battery module. A battery module according to an embodiment of the present invention comprises: a battery cell stack in which a plurality of battery cells are stacked; a first frame having a lower side and left and right sides formed to cover the battery cell stack; and a second frame having an upper side, a front side, a rear side, a left side, and a right side integrally formed to cover the upper and front and rear sides of the battery cell stack and the left and right sides of the first frame.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent No. 10-2020-0028574 filed with the Korean Intellectual Property Office on March 6, 2020, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present disclosure relates to a battery module and a method for manufacturing the battery module, and more particularly, to a battery module preventing expansion of battery cells and a method for manufacturing the battery module. Background technique [0004] Secondary batteries have drawn attention as energy sources in various products such as mobile devices and electric vehicles. A secondary battery is a powerful energy source that can replace the use of existing products using fossil fuels, and since the secondary battery does not generate by-products due to the use of energy, it is attracting attention as an environmentally friendly energy source. [0005] Recently, as the...
