Interfacial and Electrolyte Engineering for High-Performance Aqueous Zn Metal Batteries

Aqueous zinc batteries are a safe and low-cost option for large-scale energy storage, but their performance is limited by instability of the zinc metal electrode during repeated charging and discharging. This thesis develops new electrolyte additives and thin protective coatings to make zinc electrodes more stable and reliable. The research shows that regulating ion behaviour at the zinc surface can suppress unwanted reactions, prevent uneven metal growth, and greatly extend battery lifetime. These strategies improve battery efficiency, durability, and safety, offering practical solutions for future sustainable energy storage technologies.
