MULTI-LAYER ALL SOLID-STATE BATTERY COATING

A coating system for a solid-state battery includes a feeder for a first substrate foil, and an electrolyte dispenser between two electrode dispensers. The first electrode dispenser has a first mixture of a first solid active material and a first solid electrolyte therein, and deposits a first electrode layer on the foil. The electrolyte dispenser deposits an electrolyte layer on the first electrode layer. The second electrode dispenser has a second mixture of second solid active material and a second solid electrolyte, and deposits a second electrode layer on the electrolyte layer. A roller provides a second substrate foil downstream of the second electrode dispenser on the second electrode layer to form a layered structure. The system also includes drums for press rolling the layered structure to form a solid-state battery, with the layers being continuously deposited.
