"bonding interaction regulation can reduce the chance of freezing at low temperature and evaporation at high temperature... Another advantage... good mechanical properties for flexible device applications... voltage... remained constant after it was bent at different angles... electrochemical performance of the hydrogel electrolyte at 5 A·g-1 is 185 mAh·g-1. In Zn//Zn battery, the capacity retention rate of 10,000 cycles is 88 percent, and the cycle stability of 3,000 cycles is improved"
