"Low-cost and Non-flammable Eutectic Electrolytes for Advanced Zn-I2 Ba" by Junnan Hao, Libei Yuan et al.
As a burgeoning electrolyte system, eutectic electrolytes based on ZnCl2/Zn(CF3SO3)2/Zn(TFSI)2 have been widely proposed in advanced Zn-I2 batteries; however, safety and cost concerns significantly limit their applications. Here, we report new-type ZnSO4-based eutectic electrolytes that are both safe and cost-effective. Their universality is evident in various solvents of polyhydric alcohols, in which multiple −OH groups not only involve in Zn2+ solvation but also interact with water, resulting in the high stability of electrolytes. Taking propylene glycol-based hydrated eutectic electrolyte...
