Zinc-ion batteries based on water-based electrolytes are inherently safe, environmentally friendly, and economically viable. They also mitigate fire risks and thermal runaway issues associated with their lithium-based counterparts, which makes them lucrative for grid-scale energy storage. Furthermore, zinc has high capacity, low cost, ample abundance, and low toxicity. Unfortunately, current collectors utilized in zinc-ion batteries, such as graphite foil, are difficult to scale up and suffer from relatively poor mechanical properties, limiting their industrial use.

In a new study, a team of researchers from the Republic of Korea, led by Associate Professor Geon-Hyoung An at the Department of Energy and Materials Engineering at Dongguk University, has proposed graphene-coated stainless steel foil as a novel alternative current collector.
