Aqueous zinc ion batteries coupling with conventional hydrogel electrolyte have the advantages of high safety, low cost, and simple manufacturing process while they are difficult for fast charging/discharging application scenarios due to the sluggish kinetics. Herein, a new strategy is developed for synthesizing a highly-entangled polyacrylamide (HE-PAM) hydrogel electrolyte to dramatically enhance the ion transportation and mechanical stability. The developed hydrogel electrolyte has lower ionic resistance and a strong elastic modulus. After being assembled into Zn/MnO₂ batteries, the HE-PAM hydrogel electrolyte exhibits excellent cycling stability and high-rate capability under high current densities. Specifically, the Zn//HE-PAM//MnO₂ battery can resist the highest current of 35 Ag^-1, which outperforms previously reported works. Moreover, the HE-PAM hydrogel electrolyte can also support the fast charging/discharging in proton ion batteries with a high capacity retention rate of 50% under 50 Ag^-1. This progress on hydrogel electrolytes can boost the development of quasi-solid-state batteries in the fast charging/discharging aspect.
