Exposing Zn(002) Texture with Sucralose Additive for Stable and Dendrite‑Free Aqueous Zinc‑Ion Batteries (IMAGE)
Caption
- Sucralose (SCL) has been unveiled as an electrolyte additive to promote the exposure of the Zn(002) texture.
- SCL has been verified to disrupt the solvation structure around zinc ions and reduce water activity on Zn anode.
- After adding SCL additives, Zn//Zn battery achieves the cycling lifespan of 171 h at 30 mA cm−2–30 mAh cm−2 (DOD = 73.3%). Zn//Cu battery achieves a high Coulombic efficiency of 99.61% at 0.2 mA cm−2 with 0.2 mAh cm−2.
