Review identifies how electrolyte additives improve polysulfide conversion and inhibit lithium dendrites in lithium-sulfur batteries, suggesting future research directions.
Key Points
Lithium-sulfur batteries are promising for energy storage but face challenges like the shuttle effect and lithium dendrite growth.
Functional electrolyte additives can improve battery performance by enhancing sulfur fixation and altering redox pathways.
Additives help build stable interfacial layers on cathodes and anodes, addressing active material loss and dendrite formation.
Future development of these additives could lead to significantly improved lithium-sulfur battery stability and efficiency.
