Abstract

An apparatus for manufacturing unit cells includes reels, rollers, conveyors, headers, and a cutter. A lower separator sheet is unwound from a lower separator reel. A feeding roller moves the lower separator sheet in a first direction. A conveyor moves a first electrode in a second direction parallel to the first direction. A first header conveys that electrode from the conveyor and onto the lower separator sheet. An upper separator sheet is unwound from an upper separator reel. Another feeding roller moves, in the first direction, a first ordered stack of the lower separator sheet, first electrode, and upper separator sheet. Another conveyor moves a second electrode in the second direction. Another header conveys that electrode from the second conveyor and onto the upper separator sheet. The cutter cuts, at preset intervals, a second ordered stack of the lower separator sheet, first electrode, upper separator sheet, and second electrode.
