Professor Niu Li's team of Guangzhou University has made new progress in the field of lithium sulfur battery

As one of the most promising energy storage systems in the next generation, lithium sulfur battery has been widely concerned by researchers at home and abroad However, the low utilization of sulfur, the shuttle behavior of polysulfides and the slow electrochemical process seriously hinder its practical application Recently, Professor Niu Li's team from the research center of analytical science and technology of Guangzhou University successfully modified the three-dimensional nitrogen doped carbon nano sheet / molybdenum phosphide nano crystal hollow nano sphere onto the commercial battery diaphragm through the organic-inorganic hybrid strategy to solve the problem of polysulfide shuttle and self discharge in the lithium sulfur battery The modified membrane can not only provide strong physical and chemical adsorption for Polysulfide as a fixed agent, but also can be used as an electrocatalyst to accelerate the rapid conversion between polysulfide, reduce the nucleation / dissolution interface energy of lithium sulfide and inhibit the self discharge behavior of the battery The research results were published on small in the form of cover paper (DOI: 10.1002 / small 201902491) Professor Zhang Yuwei and Professor Niu Li are the corresponding authors of the paper, and Guangzhou University is the first communication unit of the paper.
