The reversible Zn−S chemistry in aqueous media is realized by introducing tetraglyme cosolvent and iodine catalyst. The cosolvent-catalyst synergy can not only activate the polar I₃⁻/I⁻ catalyst couple for S conversion but also generate an organic–inorganic interphase on Zn in situ, thus resulting in boosted cathode activity and anode stability. The strategy presents a new paradigm to stabilize aqueous Zn−S batteries.

通过助溶剂-催化剂协同作用提高 Zn-S 电池在水介质中的阴极活性和阳极稳定性

通过引入四甘醇二甲醚助溶剂和碘催化剂，实现了水介质中的可逆 Zn-S 化学。共溶剂-催化剂的协同作用不仅可以激活极性 I ₃^- /I ^-催化剂对进行 S 转化，还可以在 Zn 上原位生成有机-无机界面，从而提高正极活性和负极稳定性。该策略提出了一种稳定水系 Zn-S 电池的新范例。
