Merged summary
TL;DR - A Nature Chemical Engineering study directly repurposes zeolite-production wastewater as an aqueous zinc-battery electrolyte solvent. Its nanoscale aluminosilicate fragments form a protective interfacial layer that improves zinc deposition while reducing waste-treatment and purified-water demands.
- Negatively charged zeolite fragments self-assemble into a roughly 6–10 nm interfacial layer during zinc deposition.
- A gradient of oxygen defects creates local electric fields that promote Zn²⁺ transport, uniform deposition, and dendrite suppression.
- Zn||Cu cells achieved 99.92% average Coulombic efficiency at 20 mA cm⁻²; anode-free Zn||MnO₂ cells exceeded 500 cycles at 5C.
- The effect persisted across wastewater batches, preparation conditions, zeolite structures, and industrial samples.
