The lithium–sulfur battery (Li–S battery) is a type of rechargeable battery. It is notable for its high specific energy. The low atomic weight of lithium and moderate atomic weight of sulfur means that Li–S batteries are relatively light (about the density of water).
Currently the research focuses of lithium–sulfur battery are to improve sulfur content of the positive pole, design a stable conduction structure for the sulfur positive pole, develop a new type electrolyte that is compatible with both sulfur pole and lithium metal, etc. Qingping Wu, ...

This will necessitate the development of novel battery chemistries with increased specific energy, such as the lithium–sulfur (Li–S) batteries. Using sulfur active material in the cathode presents several desirable properties, such as a low-cost, widespread geological abundance, and a high specific capacity.
During discharging/charging process, lithium ions migrate to designated sites and capacity is produced by redox reaction of lithium ions with sulfur. Because sulfur electrode has high theoretical capacity and energy density, lithium-sulfur batteries are expected to become new generations of rechargeable battery systems.
The fundamental thermodynamic principles of sulfur redox reactions in Li–S batteries are not fully understood. A ternary phase diagram is obtained after equilibrium between sulfur, lithium sulfide and dissolved polysulfides, which accurately describes the system evolution and predicts the behavior of Li–S batteries at an arbitrary given state.
In Kang et al. (2016), the research and development of various components of lithium-sulfur batteries were processed, including cathode materials and structural design, binders, separators, electrolytes, anodes, current collectors, and some novel battery structures.
