Abstract: Embodiments described herein include electrochemical cell modules. In some aspects, an electrochemical cell module includes a first electrochemical cell and a second electrochemical cell. The first electrochemical cell includes an anode material disposed on an anode current collector, a cathode material disposed on a cathode current collector, a separator disposed between the anode material and the cathode material, and a pouch material disposed on the anode current collector and the cathode current collector. The separator extends beyond the anode material and the cathode material and the pouch material extends beyond the separator. The portion of the separator that extends beyond the outer edge of the anode material and the cathode material and the portion of the pouch material that extends beyond the outer edge of the separator are folded at an angle of about 80 degrees to about 110 degrees with respect to the anode material and the cathode material.

Abstract: Embodiments described herein relate generally to apparatuses and processes for forming semi-solid electrodes having high active solids loading by removing excess electrolyte. In some embodiments, the semi-solid electrode material can be formed by mixing an active material and, optionally, a conductive material in a liquid electrolyte to form a suspension. In some embodiments, the semi-solid electrode material can be disposed onto a current collector to form an intermediate electrode. In some embodiments, the semi-solid electrode material can have a first composition in which the ratio of electrolyte to active material is between about 10:1 and about 1:1. In some embodiments, a method for converting the semi-solid electrode material from the first composition into the second composition includes removing a portion of the electrolyte from the semi-solid electrode material. In some embodiments, the method includes mechanically compressing the intermediate electrode to remove the portion of electrolyte from the semi-solid electrode material.

Abstract: Embodiments described herein relate generally to systems and methods for continuously and/or semi-continuously manufacturing semi-solid electrodes and batteries incorporating semi-solid electrodes. In some embodiments, the process of manufacturing a semi-solid electrode includes continuously dispensing a semi-solid electrode slurry onto a current collector, separating the semi-solid electrode slurry into discrete portions, and cutting the current collector to form a finished electrode.
