Texturized removable tab and battery assembly having the same

A battery assembly comprising:

• a battery having a first surface;
• and
• a removable tab attached to the first surface of the battery, the removable tab comprising:
• a main tab layer having a first surface and an oppositely disposed second surface, wherein the main tab layer comprises a battery cell attachment region and a gripping region adjacent to the battery cell attachment region;
• a first layer disposed over the first surface of the main tab layer;
• an adhesive layer disposed over the second surface of the main tab layer, the adhesive layer extending over both the battery cell attachment region and the gripping region;
• and
• a second layer disposed over the adhesive layer only at the gripping region, and
• wherein one or both of the first layer and the second layer is a texturized layer having an average surface roughness of about 0.6 microns to about 6 microns, the texturized layer providing an external face to the removable tab, and
• wherein the main tab layer comprises first and second sidewalls in the battery cell attachment region, and at least one of the first and second sidewalls is curved inwardly, away from a circumferential edge of the battery such that a portion of the first surface of the battery is exposed between the circumferential edge of the battery and the at least one of the first and second sidewalls, when the battery cell attachment region is attached to the battery.

A removable tab for a battery cell, comprising:

• a main tab layer having a first surface and an oppositely disposed second surface, wherein the main tab layer comprises a battery cell attachment region and a gripping region adjacent to the battery cell attachment region;
• a first layer disposed over the first surface of the main tab layer;
• an adhesive layer disposed over the second surface of the main tab layer, the adhesive layer extending over both the battery cell attachment region and the gripping region;
• and
• a second layer disposed over the adhesive layer only at the gripping region, and
• wherein the second layer is a texturized layer comprising biaxially-oriented polyethylene terephthalate having an average surface roughness of about 0.6 microns to about 6 microns, the texturized layer providing an external face to the removable tab.
