Abstract

The present invention provides a battery module having reduced risk of secondary fire or explosion. In order to achieve this purpose, the battery module according to the present invention comprises: at least one cell assembly comprising a plurality of secondary batteries each having an electrode lead; a module case having an internal space formed so as to accommodate the cell assembly therein; a bus bar assembly including at least one bus bar, at least one bus bar frame, and a flame retardant sheet, the bus bar having electrical conductivity and having a plate shape, and being formed such that a portion of the electrode lead is in contact therewith; a bus bar frame which has insulating properties, on which at least one bus bar is mounted, and which has a plurality of perforations through which electrode leads of the plurality of secondary batteries pass; the flame-retardant sheet has a plate shape and is positioned in close contact with an outer side of the bus bar to seal the through hole.

Description

technical field [0001] The present disclosure relates to a battery module including a flame retardant sheet and a battery rack and an energy storage system including the battery module, and more particularly, the present disclosure relates to a battery pack having a reduced risk of secondary fire or explosion. [0002] This application claims priority from Korean Patent Application No. 10-2020-0005522 filed in Korea on January 15, 2020, the disclosure of which is incorporated herein by reference. Background technique [0003] Currently commercialized secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, and lithium secondary batteries. Among them, lithium secondary batteries have attracted attention due to advantages such as freedom of charge and discharge due to almost no memory effect, extremely low self-discharge rate, and high energy density compared with nickel-based secondary batteries. [0004] Lithium secondary batte...
