  • Patent number: 10617315
    Abstract: In various embodiments, methods and systems, of an ionic varistor system is provided. The ionic varistor system includes an electrolyte-membrane assembly having a liquid electrolyte that is enclosed in a solid electrolyte membrane. The ionic varistor system further includes conductive contacts operably coupled to the electrolyte-membrane assembly. The electrolytic-membrane assembly is operably coupled to an electrical potential surface. As the ionic concentration in the electrical potential surface is increased or decreased, some ions diffuse through the solid electrolyte membrane, causing the ions to mix with the liquid electrolyte to achieve an electrostatic equilibrium state that is thermally and mechanically stable. The liquid electrolyte and the diffused ions create an encapsulated ion channel in the electrolyte-membrane assembly.

  • Patent number: 10593985
    Abstract: A method of fabricating a multilayered thin film solid state battery device. The method steps include, but are not limited to, the forming of the following layers: substrate member, a barrier material, a first electrode material, a thickness of cathode material, an electrolyte, an anode material, and a second electrode material. The formation of the barrier material can include forming a polymer material being configured to substantially block a migration of an active metal species to the substrate member, and being characterized by a barrier degrading temperature. The formation of cathode material can include forming a cathode material having an amorphous characteristic, while maintaining a temperature of about ?40 Degrees Celsius to no greater than 500 Degrees Celsius such that a spatial volume is characterized by an external border region of the cathode material. The method can then involve transferring the resulting thin film solid state battery device.

  • Patent number: 10586977
    Abstract: Electrodes, production methods and mono-cell batteries are provided, which comprise active material particles embedded in electrically conductive metallic porous structure, dry-etched anode structures and battery structures with thick anodes and cathodes that have spatially uniform resistance. The metallic porous structure provides electric conductivity, a large volume that supports good ionic conductivity, that in turn reduces directional elongation of the particles during operation, and may enable reduction or removal of binders, conductive additives and/or current collectors to yield electrodes with higher structural stability, lower resistance, possibly higher energy density and longer cycling lifetime. Dry etching treatments may be used to reduce oxidized surfaces of the active material particles, thereby simplifying production methods and enhancing porosity and ionic conductivity of the electrodes.
