1. A redox battery cell, comprising:
a positive electrolyte reservoir having disposed therein a positive electrode and a first electrolyte having dissolved therein a first redox couple;
a negative electrolyte reservoir having disposed therein a negative electrode and a second electrolyte having dissolved therein a second redox couple;
an ion exchange membrane separating the positive electrolyte reservoir and the negative electrolyte reservoir;
a positive current collector electrically connected to the positive electrode;
a negative current collector electrically connected to the negative electrode;
a casing sealing the positive electrolyte reservoir, the negative electrolyte reservoir, and the ion exchange membrane; and
an electrically conductive bipolar plate formed on an inner surface of one or both of the positive and negative current collectors,
wherein the positive electrolyte reservoir is disposed between the ion exchange membrane and the positive current collector,
wherein the negative electrolyte reservoir is disposed between the ion exchange membrane and the negative current collector,
wherein each of the positive current collector and the negative current collector is formed of an electrical conductor and has a portion extending outside of the casing, and
wherein neither of the first electrolyte nor the second electrolyte is connected to a separate electrolyte storage container outside of the casing.
