A redox flow battery (RFB) consists of three main spatially separate components: a cell stack, a positive electrolyte (shortened: posolyte) reservoir and a negative electrolyte (shortened: negolyte) reservoir. It is an environmentally friendly and large-capacity energy storage battery that can be deeply charged and discharged. Held in tanks that can be as big as shipping containers, the electrolytes release electricity when they. . During the discharge cycle, V2+ is oxidized to V3+ in the negative half-cell and an electron is released to do work in the external circuit (either DC or, for AC systems, through an AC/DC converter). In the positive half-cell, V5+ in the form of VO2+ accepts an electron from the external circuit. .
