Target of the project tubulAir± is the development of a tubular Vanadium-air redox-flow battery with increased energy and power density for stationary appliances. To achieve this, the fluid electrolyte of the VRB on the cathode shall be replaced by an air/water steam electrode. Thus the energy density might basically be doubled compared to a VRB. To achieve a better cost effectiveness, a micro tubular cell structure will be developed.
Within the frame of this project the electrochemistry is working as a connective link between manufacturers of the single components (electrolyte, electrode, catalyst, membrane) and users of the redox-flow system. Analysis of the efficiency and stability of the components will be carried out by the electrochemistry group and the single components as well as their joint action will be characterized.
Special interest will be gained on the stability of the components under relevant conditions.
The scientific findings will be assembled to a catalogue of requirements for quality of redox-flow-batteries and their electrodes, membranes and electrolytes.
