  • Publication number: 20240120470
    Abstract: A method of manufacturing a calendered cathode structure for a hybrid lithium metal cell includes depositing a first cathode coating layer without ionic liquid onto a cathode current collector, depositing a second cathode coating layer with ionic liquid onto the first coating layer, and depositing a third cathode coating layer without ionic liquid onto the second coating layer. A calendaring process is then performed on the cathode structure comprising the cathode current collector with the first, second, and third coating layers thereon such that a predetermined thickness and porosity for the cathode structure is achieved while at the same time the ionic liquid is spread throughout the cathode electrode without reaching the cathode current collector.

  • Publication number: 20230226764
    Abstract: An improved apparatus and method provide conditioning to a powder deposited on a substrate (e.g., a web), for example, by wetting the powder in a 3D printing apparatus. To achieve this in an exemplary implementation, a wetting apparatus is located between a powder dispenser and at least one top calendering roller in a direction of movement of the substrate, wherein the wetting apparatus is configured to apply a wetting agent to the powder on the substrate before the powder passes through the calendering roller. The wetting agent is comprised of a material which increases cohesiveness of the powder to prevent the powder from adhering to the top roller. In a particular implementation, the wetting agent is steam confined to an area of the substrate where the powder passes through the wetting apparatus, without wetting other areas of the substrate which are not in the wetting apparatus.
