Boron-Modified Glass Fiber Separator by Magnetron Sputtering for Simultaneous Suppression of Zinc Dendrites and By-Product Formation in Aqueous Batteries

Key Points

• The central aim is to investigate the effectiveness of a boron-modified glass fiber separator in mitigating zinc dendrite growth and side reactions in aqueous zinc-ion batteries.
• Utilized magnetron sputtering to modify glass fiber separator with boron.
• Conducted experiments to assess dendrite growth in aqueous conditions.
• Analyzed by-product formation during battery cycling.
• Significant reduction in zinc dendrite formation observed with the boron-modified separator.
• By-product formation minimized, indicating enhanced battery stability.
• Cycling lifespan improved compared to conventional separators.
