Cosolvent Electrolyte Design for High-Voltage Aqueous Zinc–Sulfur Batteries

/Zn and reduced cell polarization of 0.32 V, outperforming most reported AZSBs. Additionally, we present design principles for cosolvent electrolytes in AZSBs, with machine learning results suggesting that the donor number and HOMO energy of the cosolvents are critical descriptors for predicting the discharge voltage of AZSBs. This work offers new insights into the development of high-performance AZSBs.
