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.

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: A power storage unit (e.g., a battery) may replace the structural components that support the display of an electronic device. The power storage unit may be adhered to the back surface of the display to provide structural support and to allow for bend or flex of the display. A self-healing layer may prevent or inhibit leaking of materials from within the power storage unit if the power storage unit is cracked or pierced. Alternatively, the power storage unit may be built on a flexible circuit that is associated with the display of the electronic device, where the flexible circuit/power storage unit may be folded around the display and affixed to the back surface of the display. The power storage unit may also be built on substrate associated with the back surface of the display. These configurations may cause a significant reduction in the depth or thickness of the electronic device.

Abstract: In an implementation, a battery package includes alternating electrodes. Each electrode includes a recessed region of electrode material layers that expose a conductive layer. Each electrode also includes openings within the electrode material layers and the conductive layer, where the openings are adjacent to the recessed regions. Multilayer electro-mechanical connectors couple exposed portions of the conductive layers of alternating electrodes to thereby electrically couple electrodes that have the same polarity. Each electrode is separated from an adjacent electrode by a separator layer. The multilayer electro-mechanical connectors can pierce the separator layers and thus, the separator layers do not require additional processing.
