Designing Antifreeze Electrolytes with Colloid‐Like Structures for High‐Rate Performance in Aqueous Zinc‐Ion Batteries (Adv. Energy Mater. 10/2025)

Aqueous Zinc-Ion Batteries

In article number 2304591, Penghui Cao, Huali Zhu, and co-workers introduce konjac glucomannan (KGM) as a dual-functional additive for aqueous zinc-ion batteries. KGM disrupts the hydrogen bond network and acts as a Zn²⁺ coordinator, forming a colloid-like electrolyte. This innovative structure enhances antifreeze performance and cycling stability, enabling long-term operation under low temperatures and high-rate conditions.
