Abstract

The invention relates to a battery module. The battery module according to the invention includes: a plurality of secondary battery cells; and a housing unit having an internal space in which the plurality of secondary battery cells are accommodated and including a plate member extending a flame or gas path.

Description

Technical field [0001] The present invention relates to a battery module. Background technique [0002] With the increase in the development and demand of mobile devices, electric vehicles, etc., the demand for the secondary battery cells as energy is increased dramatically. Since the mutual conversion between the chemical energy and electrical energy of the secondary battery cell is reversible, the secondary battery unit is a battery that can repeat charging and discharging. [0003] The secondary battery unit includes an electrode assembly such as an anode, a cathode, a diaphragm, and an electrolyte such as an anode, a cathode, a diaphragm, and an electrolyte such as a secondary battery, and a multilayer outer material of the electrode assembly (laminated film case). [0004] Additionally, a plurality of the secondary battery cells are mounted as a battery module in an electric vehicle, an energy storage device (ENERGY Storage System, ESS), and the like. [0005] However, the e...
