Chaotropic anion based “water-in-salt” electrolyte realizes a high voltage Zn-graphite dual-ion battery
Original language description
This work realizes a high-voltage and low-cost aqueous Zn–graphite dual-ion battery based on a Zn(ClO4)2 water-in-salt electrolyte with a wide electrochemical window of 2.80 V. The implementation of the supersaturated Zn(ClO4)2 water-in-salt electrolyte containing strong chaotropic ClO4− anions expands the oxidative stability of the aqueous electrolyte beyond 1.65 V vs. Ag/AgCl or 2.60 V vs. Zn/Zn2+, and facilitates reversible plating/stripping of Zn2+ with a low overpotential of <50 mV at 1 mAcm−2 and a high upper cut-off potential of 2.5 V vs. Zn/Zn2+. Consequently, the Zn–graphite dual-ion battery delivers a maximum discharge capacity of 45 mAhg−1 at 100 mAg−1 with a mean discharge voltage of ∼1.95 V and cycle life of over 500 cycles.
