1. A redox battery, comprising:
a sealed volume comprising a positive electrolyte reservoir, a negative electrolyte reservoir, and an ion exchange membrane dividing the positive and negative electrolyte reservoirs;
the positive electrolyte reservoir having a first electrolyte having dissolved therein a first redox couple;
the negative electrolyte reservoir having a second electrolyte having dissolved therein a second redox couple;
the ion exchange membrane in contact with the first electrolyte and the second electrolyte; and
a conduit disposed inside the sealed volume and directly connecting the positive electrolyte reservoir with the negative electrolyte reservoir.
