Breakthrough in research on gradient catalytic materials for lithium-oxygen batteries

Recently, Bohai University Supercapacitor Engineering Technology Research Center has made breakthroughs in the research of lithium oxycarbon battery gradient catalytic materials. The related results "Gradient Mn-La-Pt Catalysts with Three-layered Structure for Li-O2 battery" was published online on October 12, 2016 in the internationally renowned journal "Scientific Reports". Scientific Reports is a comprehensive scientific journal under the Natrure Publishing Group. It publishes original research papers that are technically reliable and of interest to professionals in various fields. It covers all aspects of the natural sciences and has important influence in the international academic field. Dr. Cai Kedi is the author of the article, Dr. Lang Xiaoshi and Dr. He Tieshi are co-authors of the article. In recent years, the team's research results have also been published in the "ACS Applied Materials & Interface", "Electrochimica Acta", "International Journal of Hydrogen Energy" and other international engineering technology sector 1 journal, and authorized lithium-ion battery direction related 9 invention patents.

Lithium-oxygen battery is a metal-air battery using lithium metal as the negative electrode and oxygen as the positive electrode reactant. It has attracted much attention in recent years due to its high theoretical specific energy and environmental friendliness. Based on the previous research, Dr. Cai Kedi proposed for the first time the ternary catalysis of manganese, lanthanum and platinum for the cathode of lithium-oxygen battery. The battery exhibited superior discharge specific capacity, energy density and long cycle life. More importantly, this work will also provide new ideas and methods for the research of other metal air batteries.
