Abstract:
Methods, stacks and electrochemical cells are provided, which improve production processes and yield flexible and durable electrode stacks. Methods comprise depositing an electrode slurry on a sacrificial film to form an electrode thereupon, wherein the electrode slurry comprises a first solvent, attaching (e.g., laminating) a current collector film, which is produced at least partly using a second solvent, onto the formed electrode, to yield a stack, wherein a binding strength of the electrode to the current collector film is higher than a binding strength of the electrode to the sacrificial film, and delaminating the sacrificial film from the electrode while maintaining the attachment of the electrode to the current collector film. Additional layers such as a cell separator and an additional electrode may be further attached using similar steps.
