Aqueous gel polymer electrolytes may, for example, have an additive compound including boron (e.g., a borate ion-containing salt) therein to configure batteries formed using the aqueous gel polymer electrolyte to increase the ionic conductivity of the gel polymer electrolyte. The addition of borax in Zinc-ion battery gel electrolytes of embodiments is configured to enhance the dissociation of zinc ions and anions, and subsequently release more mobile zinc ions. Furthermore, the interaction between borax and divalent transition metal (Zn) in electrolyte according to embodiments may enhance the transportation of mobile zinc ions.

  • Patent number: 10991942
    Abstract: Electrochemical cells of the present disclosure may include one or more multilayered electrodes. Each multilayered electrode may be configured such that active materials of the layer closest to the current collector have a lower energy to lithiate per mole, a higher energy to delithiate per mole, a different solid state diffusivity, and/or a different average particle size. This arrangement counteracts, for example, natural gradient fields and undesirable polarization found in standard lithium-ion batteries.

  • Patent number: 10957956
    Abstract: Improvements in the structural components and physical characteristics of lithium battery articles are provided. Standard lithium ion batteries, for example, are prone to certain phenomena related to short circuiting and have experienced high temperature occurrences and ultimate firing as a result. Structural concerns with battery components have been found to contribute to such problems. Improvements provided herein include the utilization of thin metallized current collectors (aluminum and/or copper, as examples), high shrinkage rate materials, materials that become nonconductive upon exposure to high temperatures, and combinations thereof. Such improvements accord the ability to withstand certain imperfections (dendrites, unexpected electrical surges, etc.) within the target lithium battery through provision of ostensibly an internal fuse within the subject lithium batteries themselves that prevents undesirable high temperature results from short circuits.

  • Patent number: 10957939
    Abstract: Systems and methods which provide a polyacrylamide (PAM) based flexible and rechargeable zinc-ion battery (ZIB) configuration are described. Embodiments of a ZIB configuration comprise a PAM based polymer electrolyte. For example, a ZIB configuration of embodiments may comprise a manganese-dioxide (MnO2) cathode, a zinc (Zn) anode, and a PAM based polymer electrolyte. The PAM based polymer electrolyte may comprise a PAM based polymer hosting one or more solutions to form a hydrogel electrolyte (e.g., crosslinked polyacrylamide hydrogel electrolyte). For example, the PAM based polymer electrolyte may be configured as a polyelectrolyte matrix host for the one or more solutions, such as may comprise a neutral solution of zinc sulfate and manganese sulfate, to achieve a stable electro chemical performance under the repetitive deformation conditions.

  • Patent number: 10840550
    Abstract: Gel electrolytes and other solid electrolytes for magnesium batteries include a monocarboranyl magnesium salt and an ether solvent having a relatively high boiling point. A polymer forms a gel or other solid matrix throughout which the monocarboranyl magnesium salt and ether solvent are uniformly distributed. Methods for making such electrolytes include combining solutions of monocarboranyl magnesium salt and polymer, followed by selectively removing the solvent in which polymer has high solubility, forcing gel formation.
