    Abstract: 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.

    Abstract: A battery cell includes: a first stacked cell and a second stacked cell that are stacked. The first stacked cell and the second stacked cell both include a plurality of first electrode plates and a plurality of second electrode plates that are alternately stacked, and on a plane parallel to the plurality of first electrode plates, a projection of the first stacked cell is within a range of a projection of the second stacked cell on the plane. The first stacked cell and the second stacked cell of different sizes are arranged in a stacked manner, so that the battery cell can be flexibly adapted to battery compartment structures of difference sizes, and a manufacturing process is simple and a mass production is easy to implement.
