SCShengchao ChaiYZYuxin ZhuJLJunpeng Li

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

Abstract

Aqueous zinc-iodine(Zn-I 2 ) batteries face a universal challenge: soluble polyiodides formed at the cathode migrate to the zinc anode, causing severe active-material loss and Zn corrosion. Here, we report a hydroxylated...
