Iron (Fe) is a common metal element, mainly used as part of the cathode material or structural material in battery technology due to its abundant reserves, low cost, and good safety, which has received extensive attention. Iron itself is not an active material in energy storage, but its compounds are widely used in batteries.
Sustainability and supply chain advantages: The resources are widely distributed with no geopolitical restrictions; It can avoid environmental and ethical issues caused by materials such as cobalt and nickel; It is easy to recycle and reuse, and is one of the important supporting materials for the battery circular economy.
