I’m delighted to share that our latest article, "Understanding the active site in chameleon-like bifunctional catalyst for practical rechargeable zinc-air batteries," has been published in Nature Communications.
🔬 Key Highlights of Our Study:
- We introduced a chameleon-inspired approach to designing bifunctional catalysts with tailored active sites, offering a universal guideline for next-generation battery materials based on conversion reactions.
- Developed a hierarchical air electrode with optimized three-phase interfaces to enhance active site conversion and kinetics in chameleon-like bifunctional catalysts.
- Key findings include:
1️⃣ A significant cathode potential difference during discharge and charge highlights OER/ORR polarization as the main cause of battery voltage fluctuations.
2️⃣ A hydrophilic layer accelerates oxygen desorption and prevents the formation of inactive regions.
3️⃣ Carbon in the cathode oxidizes into inorganic carbon species, with higher polarization voltages exacerbating degradation.
