Abstract

A battery pack according to one embodiment of the present disclosure comprises: a battery cell stack in which a plurality of battery cells including electrode leads are stacked; a plurality of bus bars including a first bus bar and a second bus bar respectively connected to at least one of the electrode leads; and a safety member in contact with each of the first bus bar and the second bus bar, in which the safety member includes a first insulating layer on the first bus bar, a second insulating layer on the second bus bar, and a conductive layer on the first insulating layer and the second insulating layer, and wherein the first insulating layer and the second insulating layer comprise a material that is electrically insulating and removed according to an increase in temperature.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of Korean Patent Application No. 10-2019-0153520 filed in the Korean Intellectual Property Office on Nov. 26, 2019, the entire disclosure of which is incorporated herein by reference. [0003] The present disclosure relates to a battery module and a battery pack including the same, and more particularly, to a battery module having improved safety against external short circuits and a battery pack including the same. Background technique [0004] Secondary batteries can be easily applied to various product groups and have electrical characteristics such as high energy density, and are commonly used not only in portable devices but also in electric vehicles or hybrid electric vehicles driven by electric drive sources and energy storage system, etc. Since such secondary batteries offer the main advantage of significantly reducing the use of fossil fuels and also genera...
