摘要：Rechargeable aqueous zinc-ion batteries (ZIBs) have emerged as promising candidates for the next generation of energy storage technology by virtue of their high energy density, safety, and low cost. However, achieving rapid and stable zinc-ion transport and preventing dendrite growth between solid-state electrolyte and Zn anode remain significant challenges. Herein, we developed a biphasic hydrogel electrolyte consist of soybean protein isolate particle clusters phase and a highly entangled elastic network phase. This structure gives the hydrogel both high toughness and high elasticity, ensuring good fatigue resistance even at low temperatures (fatigue threshold of 403 J m-2 at -60 degrees C), and guide uniform electrodeposition to inhibit zinc dendrites. Thanks to commendable balance of excellent mechanical properties and high ionic conductivity of hydrogel electrolyte, symmetrical Zn cells prepared with the biphasic hydrogel electrolyte achieve highly reversible Zn plating/ stripping within 500 h, maintaining a stable overpotential of 81.9 mV at -60 degrees C. Furthermore, the full cell incorporating PANI as the cathode and the developed electrolyte demonstrates a specific capacity of 140 mAh g-1 and maintains cycling stability over 1500 cycles at -60 degrees C. We integrate Zn||PANI cells and biphasic hydrogel strain sensors into a system that accurately monitors muscle responses during dynamic body movements.
