Patent number: 9831519Abstract: Embodiments described herein relate generally to electrochemical cells having high rate capability, and more particularly to devices, systems and methods of producing high capacity and high rate capability batteries having relatively thick semi-solid electrodes. In some embodiments, an electrochemical cell includes an anode, a semi-solid cathode that includes a suspension of an active material and a conductive material in a liquid electrolyte, and an ion permeable membrane disposed between the anode and the cathode. The semi-solid cathode has a thickness in the range of about 250 ?m-2,500 ?m, and the electrochemical cell has an area specific capacity of at least 5 mAh/cm2 at a C-rate of C/2.Type: GrantFiled: June 6, 2016Date of Patent: November 28, 2017Assignee: 24M Technologies, Inc.Inventors: Yet-Ming Chiang, Mihai Duduta, Richard Holman, Pimpa Limthongkul, Taison Tan

Patent number: 9786944Abstract: Redox flow devices are described in which at least one of the positive electrode or negative electrode-active materials is a semi-solid or is a condensed ion-storing electroactive material, and in which at least one of the electrode-active materials is transported to and from an assembly at which the electrochemical reaction occurs, producing electrical energy. The electronic conductivity of the semi-solid is increased by the addition of conductive particles to suspensions and/or via the surface modification of the solid in semi-solids (e.g., by coating the solid with a more electron conductive coating material to increase the power of the device). High energy density and high power redox flow devices are disclosed. The redox flow devices described herein can also include one or more inventive design features. In addition, inventive chemistries for use in redox flow devices are also described.Type: GrantFiled: December 16, 2010Date of Patent: October 10, 2017Assignees: Massachusetts Institute of Technology, 24M Technologies, Inc.Inventors: Yet-Ming Chiang, W.

Publication number: 20170162863Abstract: 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: September 15, 2016Publication date: June 8, 2017Inventors: Tristan DOHERTY, Pimpa LIMTHONGKUL, Asli BUTROS, Mihai DUDUTA, James C.
