They have used the conducting polymer PEDOT for the electrodes, which they have doped to transport either positive ions (cations) or negative ions (anions). It is possible in this way to manufacture completely organic redox flow batteries for the storage of, for example, energy from the sun and wind, and to compensate for load variation in the electrical supply grid. Mikhail Vagin, principal research engineer, and his colleagues at the Laboratory of Organic Electronics, Campus Norrköping, have now succeeded in producing not only a water-based electrolyte but also electrodes of organic material, which increases the energy density considerably. The electrolyte in which energy is stored in a redox flow battery can be water-based, which makes the battery safe to use, but results in a lower energy density. However, redox flow batteries often contain vanadium, a scarce and expensive metal. Further, it appears to be possible to recharge them an unlimited number of times. They are often marketed with the prefix “eco”, since they open the possibility of storing excess energy from, for example, the sun and wind. Redox flow batteries are stationary batteries in which the energy is located in the electrolyte, outside of the cell itself, as in a fuel cell. ![]()
