Abstract: Electrolyte formulations including a high salt concentration. The electrolyte formulation includes an organic solvent and a lithium salt, wherein the lithium salt is mixed with the organic solvent at a concentration of at least 20 Mole %, or at least 40 Mole %, or at least 50 Mole %. The organic solvent includes N-methyl-2-pyrrolidone, butylene carbonate, butyl propionate, pentyl acetate, ?-caprolactone, propylene glycol sulfite, ethyl methyl sulfone, butyl sulfoxide or combinations thereof. The lithium salt includes lithium bis(trifluoromethane sulfonyl) imide, lithium tetrafluoroborate, or lithium hexafluorophosphate.

Abstract: Various embodiments of a battery assembly include a first housing shell, a second housing shell, an insulator and battery components. The first housing shell has a first perimeter side wall, a first housing bottom, and a first contact area on the first housing bottom. The second housing shell has a second perimeter side wall, a second housing bottom, and a second contact area on the second housing bottom. The second housing shell is disposed in the first housing shell with the second contact area opposing the first contact area. The insulator is interposed between the first housing shell and the second housing shell to effect electrical insulation between the first housing shell and the second housing shell. The battery components include an anode electrode, a cathode electrode, and a separator interposed between the cathode electrode and the anode electrode. The separator contains an electrolyte.

Abstract: A battery having an anode, a soft-solid electrolyte, and a cathode. The soft-solid electrolyte includes a polymer soft-solid material formed from polymer combined with a solvent such as butylene carbonate, butyl sulfoxide, n-methyl-2-pyrrolidone, or ?-caprolactone.

Abstract: Plasma-polymerized hydrogel thin films and methods for making the same are provided. According to some embodiments of the present invention, plasma polymerization can be utilized to fabricate thermoresponsive hydrogel films of N-isopropylacrylamide (NIPAAm) on a substrate in a single deposition step. For example, an embodiment of the present invention includes fabricating a crosslinked polymeric structure utilized to form a thin film hydrogel. The polymeric structure fabrication method can comprise vaporizing a monomer and polymerizing the monomer using a plasma reactor. Polymerizing the monomer can crosslink the monomer to form a polymer film, and the polymer film can be deposited onto a substrate. The crosslinked density of the polymeric structure can be varied or tailored by adjusting temperature, pressure, and power conditions within the plasma reactor. Other embodiments are also claimed and described.
