Aqueous organic redox flow batteries (AORFBs) face challenges of low energy density, which can be addressed by the strategy of redox-targeting (RT) reaction integrating solid materials (SMs) with redox mediators (RMs). However, the potential matching between SM and RM is demanding and complex.
Among various energy storage systems, redox flow batteries (RFBs) are promising techniques for large-scale energy storage due to attractive characteristics of decoupled energy and power, high scalability, design flexibility and long cycling , , .
A main issue for all-liquid RFBs however is their low energy densities (∼50 Wh L −1 for the vanadium redox flow battery). 2 For scaling up the energy, an electrolyte couple with higher energy density (higher concentration or cell potential) or a larger quantity of electrolyte is needed.
For complexes with similar ligands, potentials calculated using simple implicit solvation models could be corrected using linear regression (MAE=0.051 V). Transition metal complexes are a promising class of redox mediators for targeting redox flow batteries due to the tunability of their electrochemical potentials.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
