Industrial Scalability of Zinc‐Ion Batteries: Enhanced Electrochemical Performance with High Mass Loading Electrodes on Graphene‐Coated Metal Current Collectors (Adv. Energy Mater. 22/2025)

Zinc-Ion Batteries

Zinc-ion batteries (ZIBs) have become an attractive energy storage solution due to their intrinsic safety, eco-friendly properties, and affordability. The cover image vividly represents the advancement of ZIB technology through a graphene-coated stainless steel current collector designed for roll-to-roll manufacturing processes. The innovative graphene coating, combined with heat treatment to remove surface oxides, significantly enhances electrical conductivity and corrosion resistance. This breakthrough addresses the scalability and mechanical shortcomings of conventional graphite foil collectors, paving the way for safer, cost-effective, and sustainable grid-scale energy storage systems.
