Abstract
A battery assembly includes a battery and a removable tab attached to a surface of the battery. The removable tab includes 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. The removable tab also includes a first layer disposed over the first surface of the main tab layer; and a second layer disposed over a portion of the second surface of the main tab layer only at the gripping region. 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 2 microns, the texturized layer providing an external face to the removable tab.
