The high price of raw materials is a challenge for lithium-ion battery production.

In a novel approach to address this issue, IFM researchers Dr Md Mokhlesur Rahman and Dr Tao Tao, led by Prof Ying (Ian) Chen are using low cost, environmentally friendly waste materials to produce lithium-ion batteries.

In their device, lithiated ilmenite (ilmenite is collected from beach sands) is used as a cathode and silicon recycled from waste solar panels as the battery anode. The development of an energy storage device from waste materials represents a sustainable and environmentally friendly energy expansion.
