摘要:
The large-scale, cost-effective storage of electrical energy obtained from the growing deployment of wind and solar power is critically needed for the integration into the grid of these renewable energy sources. Rechargeable batteries having a redox-flow cathode represent a viable solution for either a Li-ion or a Na-ion battery provided a suitable low-cost redox molecule soluble in an aprotic electrolyte can be identified that is stable for repeated cycling and does not cross the separator membrane to the anode. Here we demonstrate an environmentally friendly, low-cost ferrocene/ferrocenium molecular redox couple that shows about 95% energy efficiency and about 90% capacity retention after 250 full charge/discharge cycles.
