Abstract
The high safety factor of all-vanadium redox flow batteries (VRFBs) has positioned them as a leading choice for large-scale stationary energy storage. However, their further development is limited by their low energy density and high cost. Flow field performance emerges as a critical factor significantly influencing battery performance. In this paper, we propose a novel spiral flow field (NSFF), which deviates from the commonly serpentine and parallel flow fields. Our research findings demonstrate that, at a flow rate of 180 ml min−1 and a current density of 90 mA cm−2, the NSFF achieves, respectively, 3.65% and 9.8% higher energy efficiency compared to the serpentine and parallel flow fields. Moreover, the state of health of the NSFF after multiple cycles reaches an impressive level of 72.18%, surpassing that of the serpentine and parallel flow fields by 9.97% and 32.12%, respectively.
