Lithium-sulfur (Li-S) batteries with a high theoretical capacity and energy density are highly attractive. However, Li-S batteries still face persistent obstacles, such as the low electrical conductivity of sulfur and lithium sulfide, the dissolution of polysulfides, and dendrite formation on the Li metal anode. To the full demonstration of Li-S battery for electric vehicles and portable electronics, Qiang Zhang have working on the Li-S batteries with the following concepts: 1) the introduction of nanocarbon materials sheds a light on the efficient utilization of sulfur by improving the conductivity of the composites and restraining the shuttle of polysulfides; 2) the high safe Li-metal anode with dendrite-free and high utilization ratio is strongly considered; 3) the materials chemistry to control the shuttle of polysulfides and related mechanisms are highly concerned. We aim to explore the materials and chemistry principles for advanced nanostructures and their practical energy storage applications. Advanced graphene based composite materials are involved to the Li-S batteries with high capacity and long lifespan. Our research shed a new light on the complex multi-electron redox reaction and related energy storage materials, which is highly required for the sustainable society.
