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.
Claims30
A flow cell energy storage system comprising:
- (a). a flow cell comprising a cathode current collector, an anode current collector, and an ion-permeable membrane arranged to define a positive electroactive zone and a negative electroactive zone;
- and
- (b). a plurality of actuating devices comprising:
- i. a first actuating device configured to introduce an electroactive composition, directly or indirectly, between the cathode current collector and the ion-permeable membrane,
- ii. a second actuating device configured to remove an electroactive composition, directly or indirectly, from said one of the positive or negative electroactive zones,
- iii. a third actuating device configured to remove an electroactive composition, directly or indirectly, from said one of the positive or negative electroactive zones;
- and
- iv. a fourth actuating device configured to remove an electroactive composition, directly or indirectly, from said one of the positive or negative electroactive zones;
- wherein the first and second actuating devices are operatively arranged to coordinate the introduction of the electroactive compositions and the removal of the electroactive compositions by the third and fourth actuating device.
- wherein the first and second actuating devices are operatively arranged to coordinate the introduction of an electroactive composition by the first actuating device and the removal of an electroactive composition by the second actuating device.
