The instant technology discloses the Iron Ion Rechargeable Battery And Method for Making Thereof for efficient energy storage. It comprises:

Anode:

• Iron or iron-based materials like mild steel are used as the anode (the negative electrode) in these batteries.

Cathode:

• The cathode (the positive electrode) is typically a layered metal oxide coated on a current collector. This oxide acts as a host for intercalating Fe2+ ions, allowing them to move in and out of cathode during charging and discharging.

Electrolyte:

• An iron-ion conducting electrolyte is used to transport Fe2+ ions between the anode and the cathode, enables electric current flow.

Separator:

• An electrode separator membrane is placed between the anode and the cathode to prevent direct contact while allowing ion passage.

Slurry Coating:

• The cathode is coated with a slurry containing a conducting additive (often carbon-based materials like carbon nanotubes) & binding agent (e.g., poly-vinylidene fluoride).

These components help with electron transport and electrode material adhesion. During battery operation:

Charging:

• When the battery is being charged, Fe2+ ions are electroplated onto the anode, and Fe2+ ions in the cathode migrate through the electrolyte to the anode. Electrons flow through the external circuit, allowing the battery to store energy.

Discharging:

• During discharging, Fe2+ ions are stripped from the anode, migrate through the electrolyte to the cathode, and intercalate into the layered metal oxide. This movement of ions and electrons provides electrical power to external devices.
