H01M 4/64
H01M 4/04

US Classification:

429211, 429241, 296232

Abstract:

An electrochemical cell includes an anode, a semi-solid cathode, and a separator disposed therebetween. The semi-solid cathode includes a porous current collector and a suspension of an active material and a conductive material disposed in a non-aqueous liquid electrolyte. The porous current collector is at least partially disposed within the suspension such that the suspension substantially encapsulates the porous current collector.

International Classification:

H01M 8/04

US Classification:

429443

Abstract:

A multi-cell stack electrochemical device having an ion-permeable membrane separating positive and negative current collectors. A plurality of actuating devices configured to inject an electroactive composition into multiple zones within an electrochemical cell. The actuating devices are configured to apply direct pressure to internally contained electroactive composition to displace depleted electroactive material contained within an electrochemical cell. Gravity or mechanical means are used to operate the actuating device to displace electroactive composition that is internally housed.

H01M 8/24

US Classification:

429434, 429457, 429535

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.

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.

International Classification:

H01M 4/04

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.
