Abstract:
Provided is a partition of a pouch type secondary battery provided between at least two pouch type secondary batteries stacked in order to configure a secondary battery module to prevent damage of a surface of the pouch type secondary battery and shaking of the pouch type secondary battery at the time of vibration while preventing damage of the pouch type secondary battery due to a short-circuit.
Abstract:
Provided is an electrical energy storage device which may have a relatively small size and be easily surface-mounted as compared to the devices of related art, and to a method for manufacturing same. The electrical energy storage device includes a cell receiving part and an external terminal receiving part spaced from the cell receiving part. Also, the electrical energy storage device further includes: a base in which one surface of the external terminal receiving part communicates with the cell receiving part; a first external terminal including a bending part, inserted into the external terminal receiving part, and contacting a first pole surface of a cell received into the cell receiving part; and a second external terminal connected to a second pole surface of the cell, wherein the second external terminal is spaced from the first external terminal.

Abstract:
The present invention provides a bus bar assembly, which is a member electrically connecting two or more cell module assemblies to each other in order to form a battery module assembly by laterally disposing the cell module assemblies such that the cell module assemblies come into close contact with or are adjacent to each other. The bus bar assembly comprises: (a) a cover plate made of an electrically-insulating material and mounted on the upper ends of the cell module assemblies; (b) two or more conductive connection parts electrically connected to the external input/output terminals of the cell module assemblies when the conductive connection parts are mounted on the cover plate; and (c) two or more bus bars vertically mounted on the upper end of the cover plate with respect to the direction in which the cell module assemblies are arranged so as to electrically connect the conductive connection parts of the cell module assemblies to each other.
Abstract:
A sealing system for a Lithium-ion battery to extend the service life of the battery. The sealing system provides, in addition to an external case of the battery, at least one additional layer of hermetic sealing for cells within the external battery case. Films of various plastics, provided in a single layer or in a combination of layers, are used for assembling hermetically sealed enclosures for the cells.
Abstract:
The present invention provides a battery pack comprising: (a) a battery cell arranging body having two or more battery cells transversely arranged thereon, each of the battery cells being obtained by sealing an electrode assembly with a cathode/separating membrane/anode structure inside a battery case along with a liquid electrolyte; (b) a protection circuit module (PCM) that is connected to the upper end part of the battery cell arranging body, and includes connection terminals connected to the electrode terminals of the battery cells through resistance welding, a metal plate that electrically connects the battery cells, and a protection circuit for controlling the operation of the battery pack; and (c) a pack case having the battery cell arranging body and the protection circuit module mounted thereon, wherein electrical connection regions wherein the anode terminals of the battery cells and the protection circuit module are connected are welded in such a manner that a conductivity plate attached to the top of each of the connection terminals of the protection circuit module encompasses each of the anode terminals of the battery cells.
