Problems solved by technology

When the leaked electrolytic solution contacts the electrode terminals of adjacent secondary batteries, an electrical short circuit occurs between the plurality of secondary batteries, so there is a risk that thermal runaway or fire of the battery module may occur
[0009] In addition, the electrolyte solution is fatal to human health, so there is a high risk of injury or death when the electrolyte solution leaks from the battery module

Abstract

Disclosed is a battery module which can prevent an electrolyte from leaking to outside thereof when the electrolyte leaks. The battery module according to the present invention for achieving the above purpose comprises at least one cell assembly having a plurality of secondary batteries each of which has an electrode lead and which are stacked in one direction; a base plate positioned under the cell assembly and horizontally extending to support the lower portion of the cell assembly; and at least one base insulating member interposed between the cell assembly and the base plate and having a receiving part recessed downward to receive a part of the cell assembly.

Description

technical field [0001] The present disclosure relates to a battery module including a base insulating member, and more particularly, to a battery module for preventing leakage of an electrolytic solution when the battery module is used. [0002] This application claims the benefit of Korean Patent Application No. 10-2019-0119919 filed with the Korean Intellectual Property Office on September 27, 2019, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] At present, commercially available secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, lithium secondary batteries, etc. Among them, lithium secondary batteries have little or no memory effect, so they are different from nickel-based secondary batteries. Compared to lithium secondary batteries, they have attracted more attention due to their advantages such as charging at any convenient time, extremely low self-discharge ...
