Lithium-sulfur battery research and development to achieve new breakthroughs, is expected to become the next generation of power battery system
Financial sector website
Lithium-sulfur batteries with high energy density, large capacity, environmental protection, and low cost are called the development direction of the next-generation power battery system after lithium-ion batteries. However, the polysulfide generated during the use of the battery causes the battery performance to decline. It is a bottleneck affecting the application of lithium-sulfur batteries.
Recently, Li Mingtao's research group of Xi'an Jiaotong University School of Chemical Engineering designed and developed a graphene protective layer cathode material with two-dimensional structure, and obtained a lithium-sulfur battery with long cycle life. Their research results have theoretical guiding significance for improving the electrochemical performance of lithium-sulfur batteries and further industrialization.
