Abstract: Provided are electrochemical cells, comprising water-retaining components, and methods of fabricating such electrochemical cells. A water-retaining component is configured to deliver water to the positive active material during the operation of the electrochemical cell. The water-retaining component may be a part of the positive active material layer, a part of the electrolyte layer, and/or a standalone component. In some examples, the water-retaining component comprises one or more crystal hydrates (e.g., MgSO4, MgCl2, Na2SO4, Na2HPO4, CuSO4, CaCl2, KAl(SO4)2, and Mg(NO3)2), one or more water-retaining polymers (e.g., sodium polyacrylate, potassium polyacrylate, ammonium polyacrylate, and a cellulose derivative), one or more inorganic compounds (e.g., fumed silica, precipitated silica). In some examples, a method of forming an electrochemical cell comprises printing a positive active material layer, a negative active material layer, and an electrolyte layer, e.g., printing the electrolyte layer directly over the positive active material layer or the negative active material layer.

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.
