Established in 1962, lithium–sulfur (Li–S) batteries boast a longer history than commonly utilized lithium–ion batteries counterparts such as LiCoO 2 (LCO) and LiFePO 4 (LFP) series, yet they have been slow to achieve commercialization.
Herein, the development and advancement of Li–S batteries in terms of sulfur-based composite cathode design, separator modification, binder improvement, electrolyte optimization, and lithium metal protection is summarized. An outlook on the future directions and prospects for Li–S batteries is also offered.
Lithium–sulfur batteries (LSBs) have attracted much attention due to their high energy density, environmental friendliness and abundant natural reserves, and are considered a strong competitor for the next generation of energy storage devices.
The use of sulfide solid electrolytes (SEs) instead of organic liquid electrolytes can completely avoid the shuttle effect and mitigate the lithium dendrite growth problem due to the rigidity of sulfide SEs, but this does not mean that sulfide-based solid-state lithium–sulfur batteries (SSLSBs) are the optimal solution.
(iv) Formation of lithium dendrites: the occurrence of lithium dendrites on the anode during the charging and discharging (C&D) processes introduces the risk of short-circuiting, further complicating the viability of Li–S batteries in practical applications.
Specifically, lithium sulfide and metal sulfide as new active cathode materials, and lithium alloy as new anode materials are overviewed and analyzed. In addition, some newly developed interfacial modification strategies for addressing the electrode/electrolyte interfacial challenges are also outlined.
