Aqueous Zn | |I2 batteries, involving I-/I0/I+ redox, are promising yet usually facing low I2 utilization dominated by I0/I+ redox, especially under high loadings. Here, authors report a carbon-halogen bond substitution with a noncorrosive organohalide additive (2-bromoacetamide, BrAce) for a more thermodynamically favourable I0/I + , improving battery cycling under high loading and current conditions.
