Industrial Scalability of Zinc‐Ion Batteries: Enhanced Electrochemical Performance with High Mass Loading Electrodes on Graphene‐Coated Metal Current Collectors

Abstract Zinc‐ion batteries (ZIBs) have emerged as a promising energy storage solution due to their inherent safety, environmental sustainability, and cost‐effectiveness. Utilizing water‐based electrolytes, ZIBs eliminate fire risks and thermal runaway concerns, making them ideal for large‐scale energy storage systems. The high theoretical capacity, low cost, high abundance, and low toxicity of zinc further enhance its suitability for grid‐scale applications. However, conventional current collectors such as graphite foil exhibit limitations in scalability and mechanical properties, which make them unsuitable for industrial roll‐to‐roll manufacturing processes. This study addresses these limitations by…
