The research team developed an electrolyte that separates into two phases and forms a surface layer rich in electrons. To control zinc accumulation and reduce dendrite problems in water-based zinc batteries.
Key findings
- Zn||V2O5 full-cell battery tested for more than 10,000 cycles.
- Zinc poles are stable even when using high discharge depths.
- The surface layer of PEDOT and PSS ensures even zinc deposition and reduces side effects.
Why this matters globally
Hydroelectric zinc batteries offer safety and cost potential for energy storage systems. If the limitations on the lifespan and efficiency of metal poles can be solved
Thai researcher contribution
Researchers from Chulalongkorn University and the Synchrotron Light Research Institute jointly analyzed the materials and mechanisms with the Chinese team.
Limitations to consider
The circuit results in the laboratory are not equal to the lifespan in real systems. Large-scale production, cost, safety, and various operating conditions must be evaluated.
