  • Publication number: 20240055576
    Abstract: A method for making an electrode for a battery includes: providing a current collector having a current collector surface; forming an electrode precursor by arranging a plurality of extruded electrode elements on the current collector surface, each electrode element defining an element height above the current collector surface, and neighbouring electrode elements being separated by a spacing; and forming an electrode from the electrode precursor by compressing the electrode elements, thereby reducing the element height of each electrode element and closing the spacing until neighbouring electrode elements meet to form an electrode layer.

  • Publication number: 20240047729
    Abstract: Apparatus for making an electrode-electrolyte structure includes: a die head defining a substrate pathway for passage of an electrode substrate through the die head from a substrate inlet to a substrate outlet, and an electrolyte pathway for passage of an electrolyte gel through the die head; an electrode feeder for feeding an electrode substrate along the substrate pathway; and an electrolyte feeder for feeding a polymer gel electrolyte along the electrolyte pathway. The electrolyte pathway is arranged to meet the substrate pathway at a junction arranged between the substrate inlet and the substrate outlet, to extrude the electrolyte onto the electrode substrate as it is fed along the substrate pathway.

  • Publication number: 20220322693
    Abstract: Compositions and methods that relate to improved chocolate milk are provided. The chocolate milk may be shelf stable and k-carrageenan free. The chocolate milk does not undergo visually detectable phase separation for at least 7 days. The chocolate milk that does not undergo the visually detectable phase separation contains from 1%-10% micellar casein w/v. Methods for preparing shelf stable k-carrageenan free chocolate milk are also provided and include mixing cocoa powder, sugar, milk, and micellar casein to obtain a mixture, and optionally heating and homogenizing the mixture, and subsequently subjecting the mixture to High Pressure Jet Processing (HPJ) or high pressure homogenization of at least 300 MPa, thereby producing the shelf table k-carrageenan free chocolate milk. The shelf stable k-carrageenan free chocolate milk of produced using such a method may be refrigerated temperature for at least 14 days, and does not undergo detectable phase separation for at least 14 days.
