AI Technical Summary
Existing aqueous zinc-ion batteries suffer from problems such as dendritic corrosion of the zinc negative electrode, electrolyte solidification at low temperatures, and poor cycle stability of the positive electrode material. Furthermore, the introduction of organic electrolytes increases flammability.
A water/formamide mixed electrolyte is used. By adding an appropriate amount of formamide to the zinc salt aqueous solution, a non-flammable mixed electrolyte is formed, which improves the stability of the zinc negative electrode, lowers the solidification point of the electrolyte, and improves the cycle stability of the positive electrode material.
Stable operation of zinc-ion batteries at room temperature and low temperature was achieved, zinc dendrite formation was suppressed, and battery safety and cycle stability were improved.
