    摘要: A method of making an anti-perovskite solid electrolyte is provided. The method includes: providing an anti-perovskite material that is in the form of a powder; heating a die to a temperature between approximately 200 and 400° C.; loading the anti-perovskite powder into the heated die; compressing the anti-perovskite powder in the heated die; and allowing the heated die to cool to ambient temperature under pressure by maintaining the compression until the die has cooled to ambient temperature. The compression may be performed uniaxially and at a pressure in a range of 1 to 500 MPa. The anti-perovskite may undergo phase transformation, densification, and grain growth during compression at the elevated temperature. An anti-perovskite solid electrolyte formed by the method, and an anti-perovskite solid-state battery including the solid electrolyte are also provided.

    摘要: An electrochemical device (100) includes an ion exchange membrane (120), a first electrode (110) adjacent to a first side thereof and a second electrode (130) adjacent to a second side thereof. At least one of the first electrode (110) and the second electrode (130) includes a current collector layer (112, 132) and a catalyzing layer (114, 134) applied thereto. The catalyzing layer (114, 134) includes an ion-conducting polymer (116), a plurality of electroactive catalyst particles (115, 118) and an adhesive (118) that binds the polymer (116), the catalyst particles (115, 118) and the current collector layer together (112, 132). In a method of making an electrode, an ion-conducting polymer, a plurality of electroactive catalyst particles and an adhesive are mixed in a solvent, which is applied to a current collector layer. The solvent is evaporated so that the adhesive binds the polymer and the catalyst particles to the current collector.

    摘要: The present application is directed to systems, methods and devices which utilize plant based materials as an electrolyte in a power source. Embodiments may process leaves to form materials to be included in one or more of a liquid, paste, or paper-based battery cell. In some embodiments the leaf-based materials may be the primary electrolyte in the battery cell, while in other embodiments the leaf-based materials may be combined with other materials to provide for the chemical materials within the battery cell. In additional embodiments, the leaves may be processed with a textile or leather material to form a wearable cell.
