US scientists claim to have created a crossover-free, high-voltage, non-aqueous hybrid flow battery with a novel chemistry for the solid sodium anode. The device has shown a high working voltage of around 2.6 V and a coulombic efficiency of 95.0%.Redox flow batteries (RFBs) have seen their market share for stationary storage increase in recent times and the scientific community is multiplying its efforts to overcome one of the main technical issues that are hindering their deployment on a larger scale - the so-called "crossover." This phenomenon, which can cause capacity losses that can reach ...Den vollständigen Artikel lesen ...
