Researchers at the University of New South Wales (UNSW) have discovered that wine and coffee byproducts could revolutionise battery technology. This innovative approach not only promises to make batteries more efficient and eco-friendly but also addresses significant sustainability concerns.

THE CHALLENGE OF CURRENT BATTERY TECHNOLOGY

Green and circular battery supply chains are essential for the green transition because they ensure that the shift towards renewable energy sources is both sustainable and environmentally responsible. Lithium-ion batteries, which power everything from smartphones to electric vehicles, rely heavily on graphite for their anodes. However, the production of graphite is environmentally taxing, involving energy-intensive mining and purification processes. Approximately 60% of graphite is lost during these steps, which require high temperatures and strong acids, leading to a substantial environmental footprint.
