Embodiments described herein generally relate to systems and methods for continuous and/or semi-continuous fabrication of electrochemical cells having semi-solid electrodes. In some embodiments, a method may include mixing an active material, a conductive material, and an electrolyte to form a semi-solid electrode material. The method further includes evacuating 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 dispensing device to form an electrode. In some embodiments, a current collector is disposed on the bagging material. In some embodiments, the dispensing apparatus includes a top blade for top edge control and two side plates for side edge control. In some embodiments, the method may also include passing the electrode through the top blade and the two side plates to shape the electrode. 本文描述的实施例一般而言涉及用于连续和/或半连续制造具有半固体电极的电化学电池的系统和方法。在一些实施例中，一种方法可以包括混合活性材料、导电材料和电解质以形成半
