Problems solved by technology

[0006] Therefore, in the case of increasing the battery cells in order to increase the capacity of the battery module, a cell case is necessarily required, which increases the weight of the battery module or battery pack, thereby reducing its energy density
[0007] In addition, in the conventional battery module, each end plate 10 and the corresponding insulating sheet 20 are simply disposed in face-to-face contact with each other without being fixed, so that it is not easy to assemble the battery module.

Embodiment Construction

[0043] In this application, it should be understood that the terms "comprising", "having", "comprising" and the like designate the presence of the stated features, numbers, steps, operations, elements, components or combinations thereof, but do not preclude the presence or addition of one or Still other features, numbers, steps, operations, elements, components or combinations thereof.

[0044] Furthermore, the same reference numerals will be used throughout the drawings to refer to parts that perform similar functions or operations. Where a part is referred to as being connected to another part in this application, the one part may not only be directly connected to the other part, but the one part may also be indirectly connected to the other part via the other part. Furthermore, the inclusion of an element does not mean the exclusion of other elements, but rather means that other elements may be further included unless otherwise stated.

[0045] Hereinafter, a battery modul...

Abstract

The present invention relates to a battery module having improved energy density and a battery pack comprising the same, and more particularly, to a battery module and a battery pack comprising the same, the battery module comprising: a unit module stack in which unit modules are stacked horizontally or vertically with respect to the ground, each cell module comprises one or more battery cells (700) and a cell box (600) configured to accommodate the battery cells (700) therein; a pair of insulating sheets (500) positioned on the outermost side of the unit module stack; and a pair of end plates (400) located outside the pair of insulating sheets (500), in which each of the pair of end plates (400) is provided with a first protrusion (410) protruding in a direction in which the unit module stack is located, and each of the pair of insulating sheets (500) is provided with a first accommodating portion (510) configured to accommodate the first protrusion of a corresponding one of the end plates (400), the first accommodating portion has the same shape as the first protrusion.

Description

technical field [0001] This application claims the benefit of priority from Korean Patent Application No. 2020-0030584 filed on March 12, 2020, the entire disclosure of which is incorporated herein by reference. [0002] The present invention relates to a battery module having an improved energy density and a battery pack including the same, and more particularly, to a configuration such that a support portion is formed on an insulating sheet, so that it is possible to further increase the unit case without increasing the A battery module accommodating battery cells and a battery pack including the battery module. Background technique [0003] Due to increased use of mobile devices, increased complexity of mobile devices, and development of electric vehicles, the capacity required for secondary batteries used as energy sources for various electronic devices inevitably used in modern society has increased. In order to meet the needs of users, a plurality of battery cells are...
