Abstract

Systems and methods of the various embodiments may provide decoupled electrode electrochemical energy storage systems.

Claims (15)

1 . An energy storage system comprising:

a metal flow passage;

metal pellets;

one or more air electrodes; and

one or more separators separating the metal flow passage from the one or more air electrodes,

the metal pellets flowable through the metal flow passage past the one or more air electrodes.

2 . The system of claim 1 , wherein the metal pellets include iron.

3 . The system of claim 1 , wherein the iron includes direct reduced iron (DRI).

4 . The system of claim 1 , wherein the metal pellets are porous.

5 . The system of claim 1 , further comprising one or more electrolyte flow passages.

6 . The system of claim 5 , wherein an electrolyte is flowable between the metal pellets and the one or more air electrodes via the one or more electrolyte flow passages.

7 . The system of claim 1 , wherein the one or more air electrodes includes a bifunctional electrode.

8 . The system of claim 1 , wherein the one or more air electrodes includes an oxygen reduction reaction (ORR) electrode and an oxygen evolution reaction (OER) electrode.

9 . The system of claim 1 , wherein the one or more air electrodes are electrically isolated from the metal pellets as the metal pellets flow through the metal flow passage.

10 . The system of claim 9 , wherein the one or more separators include a porous insulating layer.
