Progress study on the development of lithium-sulfur batteries

Abstract With the rapid development of the new energy industry in recent years, the demand for lithium batteries is very urgent, and at the same time, the requirements for the performance of lithium batteries are getting higher and higher. Lithium-sulfur batteries, as a very competitive lithium battery, can reach as much as five times the energy density of traditional lithium batteries. However, due to various limitations in the reaction process, Li-S batteries also need to undergo various performance improvements to improve the efficiency of Li-S batteries and industrial applications. This paper introduces the advantages and disadvantages of lithium-sulfur batteries as well as future challenges. It also introduces the recent developments in lithium-sulfur batteries from three different aspects, i.e., material modification, structure-based modifications, and discussion from the perspective of electrolyte additives.
