Hanin Alhassan: A Self-Charging Zinc-Ion Battery Made with Recycled Mortar
A Self-Charging Zinc-Ion Battery Made with Recycled Mortar.
Hanin Alhassan developed a self-charging aqueous zinc-ion battery using calcium-vanadium-oxide nanostructures prepared from recycled mortar. The concept links construction waste recovery with safer aqueous battery research.
Innovation mindset: Combine two sustainability problems—material waste and energy storage—so the output of one system becomes the input of another.
Official project title: Sustainable Self-Charging Aqueous Zinc-Ion Battery Using CaVO Nanostructures Prepared From Recycled Mortar (Energy: Sustainable Materials and Design).
