Abstract

A battery module, according to one embodiment of the present invention, comprises: a module main body comprising a cell assembly stack formed by stacking a plurality of cell assemblies, and a module case for accommodating the cell assembly stack; and a pair of heatsinks arranged on the upper and lower parts of the module main body so as to discharge heat transferred from the module case. The cellassembly comprises: at least one battery cell; a cartridge for accommodating the battery cell; and a pair of thermally conductive resin layers for filling empty spaces respectively formed between thetop end of the battery cell and the cartridge, and between the bottom end of the battery cell and the cartridge.

Description

technical field [0001] The present disclosure relates to a battery module having improved cooling efficiency and a battery pack including the battery module, and more particularly, to exhibiting improved cooling efficiency and having simplified manufacturing by using cooling fins and a thermally conductive resin layer A battery module of the process and a battery pack including the battery module. [0002] This application claims priority from Korean Patent Application No. 10-2018-0087424 filed in Korea on Jul. 26, 2018, the disclosure of which is incorporated herein by reference. Background technique [0003] Secondary batteries currently in commercial use include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, and lithium-ion secondary batteries. Among these secondary batteries, lithium-ion secondary batteries have received high attention due to substantially no memory effect to ensure free charge and discharge, very low self-discharge rate, an...
