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 electrochemical cells and electrolytes used to build such cells. The electrolytes include imide salts and/or methide salts as well as fluorinated solvents capable of maintaining single phase solutions at between about ?30° C. to about 80° C. The fluorinated solvents, such as fluorinated carbonates, fluorinated esters, and fluorinated esters, are less flammable than their non-fluorinated counterparts and improve safety characteristics of cells containing these solvents. The amount of fluorinated solvents in electrolytes may be between about 30% and 80% by weight not accounting weight of the salts. Linear and cyclic imide salts, such as LiN(SO2CF2CF3)2, and LiN(SO2CF3)2, as well as methide salts, such as LiC(SO2CF3)3 and LiC(SO2CF2CF3)3, may be used in these electrolytes. Fluorinated alkyl groups enhance solubility of these salts in the fluorinated solvents. In some embodiments, the electrolyte may also include a flame retardant, such as a phosphazene, and/or one or more ionic liquids.
