Electrode potential Potential of a cell assembled of two electrodes can be determined from the two individual electrode potentials using or, equivalently, This follows from the IUPAC definition of the electric potential difference of a galvanic cell, according to which the electric potential difference of a cell is the difference of the potentials of the electrodes on the right and the left of the galvanic cell. When Δ"V" is positive, then positive electrical charge flows through the cell from the left electrode (anode) to the right electrode (cathode). Electrode potential Electrode potential, "E", in chemistry or electrochemistry, according to a IUPAC definition,
Vanadium redox battery cell electrochemistry within the electrode is poorly known. Electrolytic wetting of carbon electrodes in VRFBs is important for overcoming sources of degradation and applying appropriate operational procedures. Recently, it appears that electrolytic wetting behaviour within the electrode may be influenced by local concentration effects as well as capillary action. Rapid wetting or permeation may also leave behind undissolved gases which could cause electrode degradation. The extremely large capacities possible from vanadium redox batteries make them well suited to use in large power storage applications such as helping to average out the production of highly variable generation sources such as wind
