Ultra-High-Capacity and Dendrite-Free Zinc–Sulfur Conversion Batteries Based on a Low-Cost Deep Eutectic Solvent

battery: 95.96 and 91.57% after resting for 24 and 72 h, respectively). This work is the first authentication of Zn-S batteries based on a newly developed low-cost DES-based electrolyte, which meanwhile settles the deep-rooted low specific capacity and infamous Zn dendrite issues in conventional (de)intercalation Zn-ion batteries.
