Recently, Bohai University Supercapacitor Engineering Research Center made a breakthrough in lithium-oxygen battery gradient catalytic materials research. Related Results "Gradient Mn-La-Pt Catalysts with Three-layered Structure for Li-O2 Battery" was published online in an internationally renowned journal, "Scientific Reports" on October 12, Scientific Reports, a comprehensive science journal under the Natrure publishing group, publishes original research papers that are technically reliable and of interest to professionals in all disciplines, covering all aspects of the natural sciences and having a significant influence in international academic fields. Dr. Cai Decie is co-author of the article, the first author of the article, Dr. Lang Xiaoshi and Dr. He Tieshi. In recent years, the team's related research results have also been published in the "ACS Applied Materials & Interface", "Electrochimica Acta", "International Journal of Hydrogen Energy" and other international engineering and technology field 1 periodicals and authorize the direction of lithium-oxygen battery 9 invention patents. Lithium-oxygen battery is a kind of metal-air battery using lithium metal as negative electrode and oxygen as positive electrode reactant. Due to its advantages of high specific energy and environment-friendliness, lithium-oxygen battery has drawn much attention in recent years. On the basis of the previous studies, Dr. Cai Kedi's team proposed for the first time that a ternary gradient catalytic material of manganese, lanthanum and platinum was used for the positive electrode of lithium-oxygen batteries, which showed better discharge specific capacity, energy density and longer cycle life. More importantly, this work will also provide new ideas and methods for the research of other metal-air batteries. Research work in this area has also been awarded by Prof. Zhang Qingguo, Prof. Wang Daolin, Wei Ying, Dr. Zhang Guangju, Yang Rui and Xiao Yao from Bohai University. Dr. Yu Yujin, Fritz Huber Institute of Maple Institute, Germany, Dr. Bruce Haven National Laboratory Dr. Wang Jiajun, Beijing University of Technology Associate Professor Wang Zhenhua and the National Natural Science Foundation of China. We are a manufacturer of FRP Pressure Tank and FRP Membrane Housing. The working pressure of the FRP softener tank is designed to be 125PSI and 150PSI. The liner of the FRP Filter Tank is made of food-grade PE raw material, blow molding/rotomolding integrated molding process, epoxy resin + glass fiber winding reinforcement, automatic CNC winding is more accurate and the quality is better. Stable and more efficient, the tank mouth is connected with threaded or flanged joints, and has passed NSF, CE, ISO9001 certification. Passed more than 100,000 times of fatigue tests, more than 4 times the burst pressure.
