What is a zbfb battery?
In the early 1970s, the Exxon developed the ZBFB as a hybrid flow battery system, where the energy is stored by plating solid zinc on the anode during charging. As a result, the energy output of the ZBFBs is dependent on the anode surface area and the overall size of the electrolyte storage reservoirs.
What is the power density of a zbfb battery?
The ZBFB delivers a peak power density of 1.363 W cm −2 at room temperature. The ZBFB stably runs over 1200 cycles (∼710 h) at 200 mA cm −2 and 60 mAh cm −2. Zinc-bromine flow batteries (ZBFBs) offer great potential for large-scale energy storage owing to the inherent high energy density and low cost.
