A Hydroxylated Zwitterion Enables Dual-Modal Synergy for Stable Zinc-Iodine Batteries

Key Points

• To explore the role of a hydroxylated zwitterion in stabilizing zinc-iodine batteries.
• Investigated the formation of soluble polyiodides at the cathode
• Analyzed the migration effects on the zinc anode
• Assessed active-material loss and zinc corrosion rates
• Hydroxylated zwitterion decreased active-material loss in the battery
• Showed reduction in zinc corrosion rates
• Improved overall stability of the zinc-iodine battery system
