Sustainable electrical energy storage through the ferrocene/ferrocenium redox reaction in aprotic electrolyte
1Materials Science and Engineering Program and Department of Mechanical Engineering, The University of Texas at Austin, Austin, TX 78712 (USA).
Abstract:
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.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
