Iron chromium battery is the earliest liquid flow battery technology that emerged. It was included in NASA''s research program as early as 1974 and received support from the US Department of Energy. In 1978, iron chromium batteries were successfully developed with Fe2+/Fe3+and Cr2+/Cr3+pairs as positive and negative active materials, respectively.
Iron-chromium flow batteries were pioneered and studied extensively by NASA in the 1970s – 1980s and by Mitsui in Japan. The iron-chromium flow battery is a redox flow battery (RFB). Energy is stored by employing the Fe2+ – Fe3+ and Cr2+ – Cr3+ redox couples.
Flow batteries involve tanks filled with liquid electrolytes that are mechanically pumped through pipes to drive charge and discharge cycles. They have comparatively lower power and energy density so aren''t expected to find use in your electric car or mobile phone. Among flow battery variants, redox is the most established.
The iron–chromium redox flow battery (ICRFB) has a wide range of applications in the field of new energy storage due to its low cost and environmental protection.
