摘要： A semiconductor-based battery system comprising a primary battery that spontaneously provides power that in embodiments trickle-charges a secondary battery. The battery obtains power as heat from the surrounding environment. The primary battery is powered through internal blackbody radiation, which cools a micro-platform and provides thermoelectric power at all temperatures above absolute zero with available power increasing with temperature. Lifetime of the primary battery is not limited by electrochemical degradation over time. In embodiments, the primary battery powers an application device directly without a secondary battery.

摘要： A power supply includes a core housing having a first housing portion and a second housing portion together forming a cavity. The first housing portion is separable from the second housing portion to access the cavity. A battery core includes a plurality of battery cells received within the cavity. The plurality of battery cells are divided into a first group of interconnected battery cells and a second group of battery interconnected cells. The battery core also includes a conductor mechanically and electrically connecting a first terminal of the first group of interconnected battery cells and a second terminal of the second group of interconnected battery cells thereby connecting the first group of interconnected battery cells in series with the second group of interconnected battery cells. The conductor is disconnected from the first terminal or the second terminal when the first housing portion is separated from the second housing portion.

摘要： Embodiments are directed to establishing a direct electrical bond between a bonding connector of a contact plate and a battery cell in a battery module. In a first embodiment, an oscillating laser is used to weld the bonding connector to a battery cell terminal over a target area over which the bonding connector makes non-flush contact. In a second embodiment, the bonding connector is flattened to reduce a gap between the bonding connector and the target area on the battery cell terminal, and then laser-welded (e.g., using an oscillating or non-oscillating laser). In a third embodiment, at least one hold-down mechanism is applied over the bonding connector to secure the bonding connector to the battery cell terminal, after which the bonding connector is laser-welded to the battery cell terminal.
