Abstract

Although lithium-ion battery has been widely used in electronic devices and electric vehicles, its low theoretical specific capacity is not able to meet the requirement of high energy density. Lithium-sulfur batteries, with high theoretical capacity (1672 mAh·g-1), possess the potential to be commercialized. However, lithium-sulfur batteries still face lots of challenges such as the shuttle of high-order polysulfides and poor conductivity of sulfur and polysulfides, which hinder their commercial application. To solve these problems, solutions can be found from the structural design of not only the cathode materials, but also the battery system. This review introduces recent progress on the functional design of carbon materials for cathode, interlayer design, separator optimization and new types of separator. The relationship between structure and properties of lithium-sulfur batteries has been analyzed, the development directions of lithium-sulfur batteries are prospected.
