Embodiments described herein relate generally to systems and methods for continuously and/or semi-continuously manufacturing electrochemical cells with semi-solid electrodes. In some embodiments, a method can include mixing an active material, a conductive material, and an electrolyte to form a semi-solid electrode material. The method further includes drawing a vacuum on the semi-solid electrode material, compressing the semi-solid electrode material to form an electrode brick, and dispensing a portion of the electrode brick onto a current collector via a dispensation device to form an electrode. In some embodiments, the current collector is disposed on a pouch material. In some embodiments, the dispensation device includes a top blade for top edge control and two side plates for side edge control. In some embodiments, the method can further include conveying the electrode through the top blade and the two side plates to shape the electrode.
