Zinc-air batteries, known for their lightweight design, environmental friendliness, and wide operating temperature range, have long held promise as a lasting energy source.However, their widespread adoption has been hampered by a reliance on expensive platinum in the positive electrode, limiting their scalability and affordability. That may soon change.
A team of researchers from Anhui University of Technology and the University of Science and Technology of China have announced a notable breakthrough: a highly efficient,cost-effective catalyst for zinc-air batteries. This development, published in the prestigious journal Nature Communications on January 3rd, could revolutionize the energy sector. The research team, led by Professors Zeng Jie and Liu Mingkai of Anhui University of Technology and Associate Professor Li Hongliang of the university of Science and Technology of China, has developed a catalyst that outperforms platinum, paving the way for a more sustainable and accessible energy future.
the researchers employed a novel approach, precisely controlling the distance between individual iron atoms using an “interface anchoring strategy.” This innovative technique resulted in a close-neighbor single-atom iron catalyst that substantially surpasses the performance of platinum in zinc-air batteries.The team’s success lies in their ability too create a high-purity diatomic iron catalyst through a combination of chemical etching and nitrogen source anchoring methods.
“Researchers have proposed a general method to precisely control the distance between single atoms through an interface anchoring strategy. the close-neighbor single-atom iron catalyst constructed through this method shows better performance than the precious metal platinum in zinc-air batteries,” explains a statement from the research team.
The implications of this finding are far-reaching. The potential for cheaper, more sustainable batteries could impact everything from electric vehicles to portable electronics. The researchers have already extended their method to other non-noble metals,opening up even more possibilities for innovative battery technologies. This breakthrough represents a significant step towards a cleaner, more affordable energy future for the United States and the world.
