Abstract: Provided are flexible multi-battery assemblies and methods of manufacturing these assemblies. In some examples, a flexible multi-battery assembly comprises a first current collector, parsed into a first plurality of current collector portions such that each portion contacts one of a plurality of electrochemically active stacks. The second current collector may be continuous (e.g., to provide support to the electrochemically active stacks) or similarly parsed into a second plurality of current collector portions. Each electrochemically active stack forms one of flexible electrochemical cells in the flexible multi-battery assembly. Furthermore, at least one outer surface of the first current collector or the second outer surface is fully exposed, e.g., to allow forming electrical and mechanical connections directly to one or both current collectors. In some examples, an insulator layer covers a non-exposed surface of the other current collector.

Abstract: Described herein are smart labels, each comprising multiple wireless radios, and methods of operating such labels. For example, a smart label comprises a battery and two wireless radios having different power requirements. When the battery is no longer able to support a high-power radio (e.g., NB-IoT), the battery can still power a low-power (e.g., BLE). A battery can be specially configured and/or controlled to support the multi-radio operation of the smart label. For example, a battery can include multiple battery cells with configurable connections among these cells and radios. Furthermore, some battery components can be shared by wireless radios. The battery can also power other components of the smart label, such as sensors (e.g., temperature, acceleration, pressure, package integrity, global positioning), memory, and input/output components. In some examples, multiple smart labels form a mesh network, designed to lower the total power consumption by the radios of these labels.

Abstract: Provided are printed electrochemical cells, which utilize zinc salts for ionic transfer, and methods of fabricating such cells. In some examples, a printed electrochemical cell comprises a positive electrode with a positive current collector having a two-dimensional shape and comprising an electrolyte-facing surface formed by the graphite. For example, the positive current collector may be a graphite foil or an aluminum foil with a graphite coating.

For example, the electrolyte salt comprises a zinc salt with a concentration of at least 30% by weight in the electrolyte. The cell is fabricated by printing a positive active material layer over the positive current collector, printing one or more electrolyte layers on various cell components, and laminating a separator layer between the positive and negative electrodes while soaking the separator layer with the electrolyte.
