Embodiment Construction

[0021] refer to Figure 1-3 , according to an exemplary embodiment, there is provided an adhesive tape applicator 10 for applying a predetermined length of non-conductive adhesive tape on a battery cell 17 .

[0022] refer to Figure 11 and 12 , the exemplary battery cell 17 has a pouch-shaped body portion 18 , edge portions 19 , 20 , 21 , 22 and electrodes 25 , 26 . Edge portions 19 and 20 extend outwardly from opposite edges of pouch body portion 18 and are arranged substantially parallel to each other. Edge portions 21 , 22 also extend outwardly from opposite edges of the bag-shaped body portion 18 and are arranged substantially parallel to each other and substantially perpendicular to edge portions 19 , 20 . The electrodes 25 , 26 extend outwardly from the edge portion 22 . In one exemplary embodiment, the battery cells 17 are lithium-ion pouch-type battery cells. Of course, in alternative embodiments, other types of battery cells known to those skilled in the art may...

Abstract

A tape application machine and method are provided. The machine includes a nest device that moves along a linear rail from a first position to a second position. The nest device holds a battery cell therein. The machine further includes a tape application device that dispenses electrically non-conductive tape and applies a first portion of the tape on a first side of the battery cell. The machine further includes a tape bending device that conforms a second portion of the electrically non-conductive tape onto a second side of the battery cell. The machine further includes a tape compression device that compresses the tape on the first and second sides of the battery cell.

Description

technical field [0001] The present application relates to tape applicators and methods for applying non-conductive tape to battery cells. Background technique [0002] This application claims priority to US Provisional Patent Application No. 61 / 325,085, filed April 16, 2010, the entire contents of which are hereby incorporated by reference. [0003] Current leakage in the battery pack can create a short circuit, which can degrade the battery pack. Such a leak may occur if a metal part contacts one or more cells of the battery pack. For example, if a metal part contacts a pocket or edge portion of a battery cell, current leakage may occur at the pocket or edge portion. [0004] Accordingly, the inventors herein recognize the need for a new tape applicator to apply non-conductive tape to battery cells to reduce and / or minimize the aforementioned current leakage. Contents of the invention [0005] technical problem [0006] It is an object of the present invention to prov...
