    Abstract: Systems, methods, and computer-readable media are disclosed for improved battery performance. The systems, methods, and computer-readable media described herein may improve user experiences and prolong the battery's life. In an example method described herein, a battery may be placed within a clamp or housing that applies configurable pressure to the battery. In turn, the applied pressure may counter the swelling pressure of the battery and improve the battery's power output, reduce the internal resistance or impedance, and improve the life cycle of the battery.

    Abstract: A power source, designed to be bent or flexed during use, may include a layer of anode material having a length greater than a layer of cathode material to accommodate for movement of the cathode or anode layers during flexing of the power source. An enclosure containing the cathode and anode materials may include an inner protective layer proximate to the cathode and anode layers and a water-impermeable layer external to the inner protective layer. The water-impermeable layer may have a pleated or corrugated configuration that may be extended when the power source is bent under application of a flexure stress, preventing damage or deformation to the water-impermeable layer.

    Abstract: A modular recharging system includes an electronic device that performs diagnostics on a removable battery pack that the electronic device can use to boost the power of its internal battery. Typically, the battery pack will have a larger battery than the internal battery of the device. The electronic device determines whether the battery pack will take a charge before determining whether the battery pack is authorized to assure that an authorization failure is not due to other issues such as a dead battery, an underpowered battery, or a broken connection between devices.

    Abstract: Various embodiments are directed to a flexible battery structure comprising patterned active layers. An example battery structure comprises a sheet of current collector material, first and second active layers, and a first electrolyte layer. The first active layer may be disposed on the sheet and may comprise a plurality of active material portions and a plurality of slots, where each of the plurality of slots separates a set of at least to adjacent active material portions.
