World’s First Iron-ion Battery, Developed in India by researchers from IIT Madras

Research team from IIT Madras has developed the world’s first iron-ion battery, which promises a low-cost stable alternative to the existing mainstream lithium-ion battery.

The battery consists of an anode made of low-carbon steel, instead of pure iron, plus a cathode made of vanadium pentoxide, which is suitable for the movement of iron ion, due to its larger gap. The iron-ion battery also uses iron chlorate as electrolyte.

Compared to the traditional lithium ion batteries, the newly developed batteries from IIT are much more cost effective, and features slightly better storage capacity and stability.
