Abstract:
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.

Assignee:
24M Technologies, Inc. - Cambridge MA
International Classification:
H01M 4/82
US Classification:
296231, 141 11
Abstract:
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.

Assignee:
24M TECHNOLOGIES, INC. - Cambridge MA
International Classification:
H01M 4/04
US Classification:
429209, 264104
Abstract:
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.

Abstract:
A static semi-solid filled energy storage system having a plurality of static cells, each cell comprising an ion permeable membrane separating positive and negative current collectors and positioned to define positive and negative electroactive zones. Electroactive material is delivered to the electroactive zones via a plurality of manifolds. The manifolds are injected with an electronically insulating barrier that is configured to seal each static cell from its neighboring static cell. Valves are used to allow gas created from the electrochemical reactions to be released from the system. Coolant may be introduced to dissipate heat from the system.

US Patent:
6599662, Jul 29, 2003
Filed:
Jan 7, 2000
Appl. No.:
09/479154
Inventors:
Yet-Ming Chiang - Framingham MA
Gerbrand Ceder - Wellesley MA
Pimpa Limthongkul - Somerville MA
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H01M 458
US Classification:
4292181, 4292311, 4292319, 4292315, 429217
Abstract:
This invention provides a composite material for use as an electrode in electrochemical devices. An electroactive composite material includes a first electroactive metal, the electroactive material including a phase enriched in a metal or metal alloy, Me , capable of intercalating or alloying with a species selected from the group consisting of alkali metals and hydrogen, and a second material having the first active material intimately mixed therein. The second material includes a metal oxide, Me O , wherein the metals Me have a less negative Gibbs free energy for alloying or compound formation with oxygen than the metals that comprise Me O. The materials of the invention comprise a first material that is an elemental metal, metal alloy, metal oxide, or other metal compound, selected so that it is able to alloy with lithium, and prepared in a dispersed one-, two- or three-dimensional form. The first material is intimately mixed with or dispersed within a second material that may be substantially conductive to electrons or electron holes or lithium ions. The composite material may be prepared by a process known as âpartial reductionâ or âinternal reduction,â in which a precursor to the first material is preferentially reduced, or the process known as âpartial oxidation,â in which a precursor to the second material is preferentially oxidized.
