Battery cell assembly
First Claim
1. A battery cell assembly, comprising:
- a pouch battery cell having an external pouch housing and first and second electrical terminals extending from the external pouch housing;
the external pouch housing having a central housing pouch portion and a peripheral lip member extending around a periphery of the central housing pouch portion;
the peripheral lip member having a first peripheral lip pouch portion with a first extension pouch portion, a first arcuate-shaped pouch portion, and a first end pouch portion;
the first extension pouch portion extending outwardly from the central housing pouch portion in a first direction, the first arcuate-shaped pouch portion being coupled to and between the first extension pouch portion and the first end pouch portion; and
a first tube contacting the first extension pouch portion and the first arcuate-shaped pouch portion of the peripheral lip member of the external pouch housing, the first arcuate-shaped pouch portion being wrapped around a portion of a periphery of a first tube portion of the first tube, the first end pouch portion of the peripheral lip pouch portion of the peripheral lip member having a weld interface with a top surface of the first extension pouch portion such that the first peripheral lip pouch portion extends 360 degrees to define and enclose a first interior space that is sized and shaped to receive the first tube portion of the first tube therein, and the first tube portion of the first tube being disposed within the first interior space; and
wherein the external housing is constructed of a sheet, the sheet being formed by laminating a polymer film on a metal sheet made of aluminum.

Abstract
A battery cell assembly includes a pouch-type battery cell having a battery member, an external housing, and first and second electrical terminals. The external housing has a central housing portion and a peripheral lip member extending around a periphery of the central housing portion. The central housing portion encloses the battery member therein. The first and second electrical terminals are electrically coupled to the battery member and extend outwardly from the peripheral lip member. The assembly further includes a first tube disposed against the peripheral lip member of the external housing. The peripheral lip member extends around the first tube such that the first tube is at least partially disposed within a first interior region defined by the peripheral lip member.
