Free QuoteIts advantages include long cycle life, modular design, and high safety [7, 8]. The iron-chromium redox flow battery (ICRFB) is a type of redox flow battery that uses the redox reaction between iron and chromium to store and release energy . ICRFBs use relatively inexpensive materials (iron and chromium) to reduce system costs .
The electrolyte in the flow battery is the carrier of energy storage, however, there are few studies on electrolyte for iron-chromium redox flow batteries (ICRFB). The low utilization rate and rapid capacity decay of ICRFB electrolyte have always been a challenging problem.
Unlike conventional iron-chromium redox flow batteries (ICRFBs) with a flow-through cell structure, in this work a high-performance ICRFB featuring a flow-field cell structure is developed. It is found that the present flow-field structured ICRFB reaches an energy efficiency of 76.3% with a current density of 120 mA cm−2 at 25 °C.
The flow battery can provide important help to realize the transformation of the traditional fossil energy structure to the new energy structure, which is characterized by separating the positive and negative electrolytes and circulating them respectively to realize the mutual conversion of electric energy and chemical energy [,, ].
The vanadium redox flow battery (VRFB), the most developed aqueous RFB, , , , , is estimated to have a vanadium material cost of $189 kWh −1 and a system cost of $325 kWh −1 , which are far higher than the cost target of $100 kWh −1 for the energy storage system set by US Department of Energy ARPA-E .
Different from the traditional battery carbon felt (CF) electrode, the carbon cloth (CC) made of carbon fiber is used as the battery electrode in the experiments in this paper, which has the characteristics of light weight, high strength, and excellent conductivity [, , ].
