    Abstract: Systems, methods, and computer-readable media are disclosed for swelling resistant pouch batteries. In one embodiment, an example battery may include a pouch having an aluminum layer with a first portion and a second portion, and at least one cell that is partially positioned within the pouch. The at least one cell may include an anode, a separator, a cathode, and an electrolyte. Example pouch batteries may include a circuit electrically coupled to the cathode and to the first portion of the aluminum layer, where the circuit is configured to cause a electric potential difference at the aluminum layer with respect to the anode, and a first electrical contact electrically coupled to the first portion of the aluminum layer.

    Abstract: The time remaining until a charge-based event occurs on a computing device can be determined and notification provided to the user in order to prevent a shutdown due to loss of charge, extend the lifetime of the battery, and prevent a device lockout, among other such advantages. The current charge and information about the battery and device can be used to calculate various time periods, such as the time until a 0% state of charge (SOC) whereby a user will be unable to use the device until charging, as well as the time until a 0V lockout, whereby the device will become unusable. The time period and a charge-by date can be displayed on the device at the appropriate time(s), and notifications can be generated when the device is nearing a critical state. Such information also indicates to warehouses when devices become unsellable or at least require charging.

    Abstract: Aspects of the disclosure relate to graphene-based battery packaging. In one aspect, the graphene-based battery packaging can include an assembly of translucent members, including a thin graphene-based member which can be embodied or can comprise a film of graphene layers, a film of graphene oxide, or a combination thereof. In another aspect, the graphene-based member can be assembled to form an interlayer between two of the translucent members in the assembly. In certain aspects, each of the two translucent members can be embodied in or can include a thermoplastic material. In another aspect, at least one of the translucent members in the assembly can be doped with aggregates that provide a predetermined color to the assembly. In one aspect, the graphene-based member can provide substantive isolation between translucent members separated thereby, thus mitigating diffusion of atoms, molecules, and/or particulates between such members.

    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 battery thermal shield is used with a battery to reduce peak temperature exposure caused by a short of a battery from physical damage to the battery (e.g., the battery being pierced by a metal object). The thermal shield may be a highly thermal-conductive substance, such as a film, adhesive, gel, and/or other substance, that acts as an efficient heat spreader. Unlike a typical heat sink or heat fins, the thermal shield may have a low profile and be configured to spread a rapid onset of heat at a localized point or area (e.g., a location of an internal short) to a wider area to reduce a peak (maximum) temperature caused by a short of a battery. The thermal shield may be at least partially formed of graphite which may be adhered to the battery.
