Progress in the Optimization of Electrode Modification for Ferrochromium Liquid Flow Batteries
As an electrochemical energy storage device with low cost,high flexibility,fast response time,simple structure and wide temperature range,the iron-chromium flow battery(ICFRB)has attracted a lot of attention in recent years because it can effectively solve the problem of volatility of renewable energy sources such as wind and solar.As a key component of the battery,the performance of the electrode directly affects the efficiency and cycle stability of the battery.In this paper,we will review the research progress of ICFRB electrode modification and improvement,and introduce the related strategies and methods,including oxidation-containing functional groups,metals and metal oxides.These modification means can effectively improve the electrochemical performance of the electrodes,increase the energy conversion efficiency and extend the cycle life of the batteries,which provide important technical support and theoretical guidance for the commercial application of ICFRB.
