Abstract
The dangers of short-circuiting and lithium metal plating during recharging of a unitary laminate lithium-ion intercalation battery cell are alleviated by trimming the periphery of the cell with a transverse slicing cut made at an angle from the perpendicular of the major plane surface of the cell. The resulting angled peripheral edges of the cell provides greater edge separation between electrode layers and reduces the occurrence of metal-plating accumulation of lithium ions at the edge surface of the negative electrode.
