Lithium Batteries – Lithium Secondary Batteries – Lithium All-Solid State Battery | Production

The replacement of the liquid electrolyte by a solid electrolyte leads to changed requirements for the solid/solid interfaces, especially in terms of (electro)chemical and mechanical stability, but also requires adjustments in the manufacturing process of the batteries themselves. In addition, adjustments are required depending on the type of electrolyte selected - polymer, sulfide, oxide or thin film. This results in a wide range of process combinations and cell concepts, the central element of which is a multilayer structure consisting of current collectors, (composite) electrodes and the electrolyte-separator, with the interface between the individual components being of central importance.
