Abstract

The present invention provides a battery module, and the battery module includes a battery stack formed by stacking a plurality of battery cells respectively including electrode tabs on each other; and bus bar assemblies located on sides of the battery stack, from which the electrode tabs are drawn out, to electrically connect the plurality of battery cells to each other through a plurality of electrode tabs, wherein each of the bus bar assemblies includes a plurality of openings configured to hold the plurality of electrode tabs, and each of the plurality of openings includes an insertion portion formed by opening one side thereof so that the electrode tab is slidely inserted in a direction perpendicular to a direction in which the electrode tabs are drawn out.

Description

technical field [0001] One embodiment of the present invention relates to a battery module and a manufacturing method thereof. Background technique [0002] Due to the development of cutting-edge fields such as digital cameras, mobile phones, notebook computers, hybrid vehicles, etc., research into rechargeable and dischargeable secondary batteries is being actively conducted. The secondary battery can be exemplified by a cadmium-nickel battery, a nickel-metal hydride battery, a nickel-hydrogen battery, or a lithium secondary battery. Among them, the operating voltage of lithium secondary batteries is above 3.6V, which can be used as a power source for portable electronic devices, or multiple lithium secondary batteries can be connected in series and used in high-output hybrid vehicles, which is different from cadmium-nickel batteries or nickel-nickel batteries. Compared with metal hydride batteries, the operating voltage is three times higher, and the characteristics of en...
