Abstract: Battery packs having jelly roll battery cells of different designs or capacities may have an imbalance in the charging and/or discharging current supplied to and provided by each jelly roll due to differences in capacity specific impedance between the battery cells of the battery pack. A C-rate (i.e., current relative to rated capacity) of a first and second battery cell connected in parallel may be balanced by altering properties of an active layer and/or a thickness of a current collector of the second battery cell to reduce an impedance of the second battery cell.

Abstract: Battery packs having jelly roll battery cells of different capacities may have an imbalance in the charging and/or discharging current supplied to and provided by each jelly roll due to differences in capacity specific impedance between the battery cells of the battery pack. A C-rate (i.e., current relative to rated capacity) of a lower capacity first battery cell and a higher capacity second battery cell connected in parallel may be balanced by repositioning and/or increasing the number of cathode tabs and anode tabs of the second jelly roll battery cell to reduce an impedance of the second battery cell.

Abstract: The disclosed technology relates to balanced battery packs having battery cells of different capacities with higher capacity battery cells having a reduced impedance compared to lower capacity battery cells in the battery pack. The battery pack includes at least a first and second battery cell connected in parallel, with the second battery cell having a higher capacity than a capacity of the first battery cell. Tabs extending from electrodes of the second battery cell are disposed near a center of the electrodes to reduce an impedance of the second battery cell.

Abstract: The present disclosure discloses a battery pouch that includes a cavity. The battery pouch also includes a first transition between a first side of the battery pouch and a second side of the battery pouch. The first side of the battery pouch includes a first sealed portion having a minimum threshold distance between the cavity and the edge of the battery pouch. More specifically, the first sealed portion is located between a first outer edge of the cavity and a first outer edge of the battery pouch. The battery pouch also includes a second side having a second sealed portion with minimum threshold distance. Other embodiments are also described and claimed.

Abstract: A multi-layer laminate sheet suitable to form a battery pouch is described. The laminate sheet includes a core metal layer, a sealant laver, and an insulating layer. The sealant layer is bonded to one surface of the core metal layer, and the insulating layer is bonded to the other surface of the core metal layer. The insulating layer has a width that is greater than the width of the core metal layer, such that the insulating layer extends past two edges of the core metal layer. When the pouch is formed by folding the laminate sheet, the insulating layer protects the edges of the core metal layer of the laminate sheet from being exposed around the edges or sides of the pouch. Other embodiments are also described and claimed.
