In this study, an anti-freezing hydrogel electrolyte based on CO2-derived cyclic carbonate crosslinked with potassium polyacrylate/polyacrylamide for sustainable Zn-ion battery is reported. The CO2-sourced hydrogel electrolyte with wealthy polar functional groups exhibits high flexibility and good specific capacity, with 80.4% capacity retention compared to 25 degrees C at -20 degrees C. Additionally, the hydrogel electrolyte can be degraded on demand in alkaline conditions.
Low-temperature operation of hydrogel electrolyte is limited by their poor ionic conductivity. Meanwhile, greener and sustainable batteries are in demand from an environmentally friendly perspective. Herein, we report an anti-freezing hydrogel electrolyte based on CO2-derived cyclic carbonate crosslinked with potassium polyacrylate/polyacrylamide for sustainable Zn-ion battery. Such a CO2-sourced hydrogel electrolyte with wealthy polar functional groups enables its high flexibility (twisting, compressing, and stretching) and good specific capacity (80.4% retention of the counterpart at 25?degrees C) at-20 degrees C. Furthermore, the spent hydrogel electrolyte can subsequently be degraded on demand in alkaline conditions. This work provides an effective strategy to integrate CO2-sourced anti-freezing and degradable hydrogel electrolytes for sustainable energy storage devices.
