Using a hybrid fixture, application of an appropriate external pressure on Li-metal pouch cells with a liquid electrolyte considerably reduces cell swelling. Mapping of the pressure distribution across the cell surface provides insight into the electroplating process that could inform strategies to overcome uneven Li plating on the Li-metal surface.
