Abstract: The disclosed technology relates to battery packs having battery cells of different designs or capacities with 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 a battery pack. The battery pack includes at least a first and second battery cell connected in parallel, with a thickness of an active layer and/or current collector of a battery cell having an altered thickness to reduce an impedance of the battery cell.

Abstract: This application relates to a battery system for reducing spacing between components in an electronic device. The battery system includes a housing surrounding an electrode assembly and a connection module. The housing is rigid or semi-rigid and connected to a common ground. The battery system can be positioned in the electronic device to contact components without damaging the components. In some embodiments, the battery system can be used as a structural element in the electronic component.
