Are lithium-sulfur batteries the future of energy storage?

Lithium-sulfur batteries (Figure 2), like solid-state batteries, are poised to overcome the limitations of traditional lithium-ion batteries (Wang et al., 2023). These batteries offer a high theoretical energy density and have the potential to revolutionize energy storage technologies (Wang et al., 2022).

Can SB lithiophilic interface be used in Li-S batteries?

Chen and coworkers also constructed a lithiophilic interface of Sb on Li metal for application in Li-S batteries . The Li-S battery with the Sb-Li anode maintained a high initial discharge capacity of around 915 mAh g −1 at 1 C with a capacity retention of around 83% after 400 cycles (Fig. 19 c).

Can Li-S batteries be produced on the industrial level?

Undoubtedly, these efforts have positive impact on reaction kinetics that can lead to extraordinary electrochemical performance of batteries on the laboratory scale but several challenges concerning the sulfur loading, sulfur content and E/S ratio need to be further addressed before the production of Li-S batteries on the industrial level.

How can electrolyte chemistry improve the performance of Li-S batteries?

Furthermore, advances in electrolyte chemistry, such as the use of high-concentration electrolytes, functional additives, and protective coatings (solid-electrolyte interface) have been shown to successfully suppress polysulfide dissolution, resulting in enhanced overall electrochemical performance of Li-S batteries.

What is the discharge capacity of a Li-s battery?

When utilizing in Li-S batteries, an initial discharge capacity of 1 139 mAh g −1 at 100 mA g −1 was achieved . After cycling for 100 times, its discharge capacity still remained at 761 mAh g −1. Similarly, the rationally hybridized PVDF-HFP with LiF was also investigated .

Which part of the i-li Island dissolves and produces black solid electrolyte interphase (SEI) residuals?

The part of the i-Li island close to the Li electrode dissolves and produces black solid electrolyte interphase (SEI) residuals on the Cu substrate, which are composed of Li 2 O, LiF, and some organic moieties (C–C, O–C=O, C–O) (Extended Data Fig. 2a).
