Patent number: 11888144Abstract: A method of manufacturing an electrochemical cell includes transferring an anode semi-solid suspension to an anode compartment defined at least in part by an anode current collector and an separator spaced apart from the anode collector. The method also includes transferring a cathode semi-solid suspension to a cathode compartment defined at least in part by a cathode current collector and the separator spaced apart from the cathode collector. The transferring of the anode semi-solid suspension to the anode compartment and the cathode semi-solid to the cathode compartment is such that a difference between a minimum distance and a maximum distance between the anode current collector and the separator is maintained within a predetermined tolerance. The method includes sealing the anode compartment and the cathode compartment.Type: GrantFiled: March 1, 2022Date of Patent: January 30, 2024Assignee: 24M Technologies, Inc.Inventors: Alexander H. Slocum, Tristan Doherty, Ricardo Bazzarella, James C. Cross, III, Pimpa Limthongkul, Mihai Duduta, Jeffry Disko, Allen Yang, Throop Wilder, William Craig Carter, Yet-Ming Chiang

In some embodiments, an apparatus includes a multi-layer sheet for encasing an electrode material for an electrochemical cell. The multi-layer sheet including an outer layer, an intermediate layer that includes a conductive substrate, and an inner layer disposed on a portion of the conductive substrate. The intermediate layer is disposed between the outer layer and the inner layer. The inner layer defines an opening through which a conductive region of the intermediate layer is exposed such that the electrode material can be electrically connected to the conductive region. Thus, the intermediate layer can serve as a current collector for the electrochemical cell.Type: ApplicationFiled: March 28, 2023Publication date: November 23, 2023Applicant: 24M Technologies, Inc.Inventors: Ricardo BAZZARELLA, Alexander H.

Publication number: 20220285669Abstract: Embodiments described herein generally relate to semi-solid suspensions, and more particularly to systems and methods for preparing semi-solid suspensions for use as electrodes in electrochemical devices such as, for example batteries. In some embodiments, a method for preparing a semi-solid electrode includes combining a quantity of an active material with a quantity of an electrolyte to form an intermediate material. The intermediate material is then combined with a conductive additive to form an electrode material. The electrode material is mixed to form a suspension having a mixing index of at least about 0.80 and is then formed into a semi-solid electrode.Type: ApplicationFiled: May 26, 2022Publication date: September 8, 2022Applicant: 24M Technologies, Inc.Inventors: Tristan DOHERTY, Pimpa LIMTHONGKUL, Asli BUTROS, Mihai DUDUTA, James C.
