As part of a new milestone, a research team from IIT (Indian Institute of Technology) Madras has made the world’s first-ever iron-ion battery as a replacement to the currently used lithium-ion batteries.

The iron-ion battery comprises an anode made of low-carbon steel along with a cathode made up of vanadium pentoxide. In addition to this, the electrolyte in the iron-ion battery is made of iron chlorate.For those who don’t know, the anode is the positively-charged electrode in a battery while the cathode is a negatively-charged electrode. Developing iron-ion batteries is much better as it is a relatively cheap process as compared to producing lithium-ion batteries, which acts as a disadvantage for the latter.The iron-ion battery comes with better storage capabilities and stability, which proves to be an edge over lithium-ion batteries in the market.While lithium-ion batteries are slightly unsafe to use because they tend to overheat, iron-ion batteries are comparatively safer to use. The safety factor is ensured by iron’s incapacity to make dendrites, which, in turn, prevents a short circuit.fossbytes.com
