Methods and systems for laminating layers of solid-state batteries continuously or semi-continuously

A system, comprising:

• a plurality of upstream spools configured to pay off two or more component layers of a solid-state battery, the two or more component layers comprising at least one of a continuous ribbon substrate or a carrier film;
• a set of rollers downstream of the plurality of upstream spools, the set of rollers configured to converge the two or more component layers in a stacked arrangement;
• and
• a press disposed downstream of the set of rollers, the press comprising a first pressing chamber and a second pressing chamber configured to apply pressure to a section of the two or more component layers to laminate the two or more component layers in the section;
• wherein the first pressing chamber is configured to apply a first pressure uniformly over a first surface area and the second pressing chamber is configured to apply a second pressure uniformly over a second surface area, the first surface area being substantially equal to the second surface area and the section of the two or more component layers corresponding to the first surface area and the second surface area over which the pressure is uniformly applied;
• and
• wherein the first pressure is substantially equal to the second pressure.
