The performances of a vanadium redox flow battery with interdigitated flow field, hierarchical interdigitated flow field, and tapered hierarchical interdigitated flow field were evaluated through 3D numerical model.
Vanadium redox flow battery (VRFB) is an essential technology for realizing large-scale, long-term energy storage. Among its components, the flow field structure plays a crucial factor affecting the battery performance. So far, there still exists uneven electrolyte distribution leading to low efficiency.
Conclusions The stack is the core component of large-scale flow battery system. Based on the leakage circuit, mass and energy conservation, electrochemicals reaction in porous electrode, and also the effect of electric field on vanadium ion cross permeation in membrane, a model of kilowatt vanadium flow battery stack was established.
Author to whom correspondence should be addressed. In vanadium redox flow batteries, the flow field geometry plays a dramatic role on the distribution of the electrolyte and its design results from the trade-off between high battery performance and low pressure drops.
Lithium-ion batteries (LIBs) and hydrogen (H 2) are promising technologies for short- and long-duration energy storage, respectively. A hybrid LIB-H 2 energy storage system could thus offer a more cost-effective and reliable solution to balancing demand in renewable microgrids.
Battery energy-storage systems typically include batteries, battery-management systems, power-conversion systems and energy-management systems 21 (Fig. 2b).
Compared to Just LIB or Just H2, the hybrid system provided significant cost reductions (see Fig. 5). Relying on only LIB for energy storage ($74.8 million) was more expensive than relying on only H 2 ($59.2 million), and significantly more expensive than the hybrid case ($43.3 million).
The rise in renewable energy utilization is increasing demand for battery energy-storage technologies (BESTs). BESTs based on lithium-ion batteries are being developed and deployed. However, this technology alone does not meet all the requirements for grid-scale energy storage.
