Problems solved by technology

[0006] However, in general, since the terminals protrude from the side of the electrode assembly, there is a problem that a separate external part is required to connect a plurality of supercapacitors or a plurality of secondary batteries in series
[0007] In addition, generally, since the terminal protrudes from the side of the electrode assembly, the width of the terminal is relatively small, which causes problems of increased terminal resistance and heat generation.

Abstract

An energy storage module may include a first energy storage device and a second energy storage device, each energy storage device including an electrode assembly, an outer member housing the electrode assembly therein, and an electrode lead bonded to an electrode disposed in the electrode assembly, wherein the first energy storage device and the second energy storage device are stacked in a vertical direction (V) such that the positive electrode lead of the first energy storage device and the negative electrode lead of the second energy storage device are electrically connected to each other.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority from Korean Patent Application No. 10-2020-0189807 filed on December 31, 2020 and Korean Patent Application No. 10-2021-0017059 filed on February 5, 2021, for all purposes , the entire contents of which are incorporated herein by this reference. technical field [0003] The present invention relates to an energy storage module and to an energy storage module having a structure in which a plurality of energy storage devices are stacked. Background technique [0004] In general, a supercapacitor or a secondary battery including an electrode assembly made by stacking electrodes and separators is provided with terminals configured to be electrically connected to external components. [0005] Such terminals generally have a structure protruding outward from the supercapacitor or secondary battery. In particular, the terminal usually has a structure protruding from the side of the electrode ...
