“…Similar results were also reported by Wang et al. and Nazar et al., who fabricated Li 2 S/Li 2 S 2 ‐organosulfides/organopolysulfides, and a Li 3 PS 4 /PDMS hybrid layer, respectively, to stabilize Li metal anodes . An artificial layer composed of Cu 3 N nanoparticles joined together by styrene butadiene rubber was proposed by Cui and co‐workers .…”

Lithium (Li) metal is considered as the most promising anode material for rechargeable high‐energy batteries. Nevertheless, the practical implement of Li anodes is significantly hindered by the growth of Li dendrites, which can cause severe safety issues. To inhibit the formation of Li dendrites, coating an artificial layer on the Li metal anode has been shown to be a facile and effective approach. This review mainly focuses on recent advances in artificial layers for stable Li metal anodes. It summarizes the progress in this area and discusses the different types of artificial layers according to their mechanisms for Li dendrite inhibition, including regulation of uniform deposition of Li metal and suppression of Li dendrite growth. By doing this, it is hoped that this contribution will provide instructional guidance for the future design of new artificial layers.

“…The PS concentration in the dual‐additive electrolyte is critical for the stability of the in situ formed SEI since a highly concentrated PS (>0.5 m for S) fails to maintain a smooth and firm anode surface . Recently an interesting work was presented by Wang's group using organo‐polysulfide as electrolyte additive for stable lithium anode . The poly(sulfur‐random‐triallylamine) takes participation in anode SEI formation by generating both inorganic Li salts (Li 2 S/Li 2 S 2 ) and organic units.…”

Intermediate polysulfides (S , where n = 2-8) play a critical role in both mechanistic understanding and performance improvement of lithium-sulfur batteries. The rational management of polysulfides is of profound significance for high-efficiency sulfur electrochemistry. Here, the key roles of polysulfides are discussed, with regard to their status, behavior, and their correspondingimpact on the lithium-sulfur system. Two schools of thoughts for polysulfide management are proposed, their advantages and disadvantages are compared, and future developments are discussed.

“…Lithium‐metal has the potential to become the next‐generation anode material due to its high theoretical specific capacity (3860 mAh g −1 ) and low redox electrochemical potential (−3.04 V vs standard hydrogen electrode) . When matched with conversion‐type S, sulfides, and fluorides, much higher energy densities (≈900 Wh kg −1 ) can be obtained for the corresponding Li‐metal batteries (LMBs) .…”

Li-metal is considered as the most promising anode material to advance the development of next-generation energy storage devices owing to its unparalleled theoretical specific capacity and extremely low redox electrochemical potential. However, safety concerns and poor cycling retention of Li-metal batteries (LMBs) caused by uncontrolled Li dendrite growth still limit their broad application. Herein, liquid polydimethylsiloxane (PDMS) terminated by -OCH 3 groups is proposed as a graftable additive to reinforce the anode dendrite suppression for LMBs. Such a grafting triggers the formation of a conformal hybrid solid electrolyte interphase (SEI) with increased fractions of LiF and Li-Si-O-based moieties, which serve as a rigid barrier and ionic conductor for uniform Li-ion flow and Li-mass deposition. The grafting protected anode endows Li/Li symmetric cells with a long lifetime over 1800 h with a much smaller voltage gap (≈25 mV) betweenLi plating and stripping, than the naked anode. The coulombic efficiency values for Li/Cu asymmetric cells in carbonate electrolyte can reach up to 97% even at a high current density of 3 mA cm −2 or high capacity up to 4 mAh cm −2 . The liquid PDMS additive shows advantage over solid siloxane additives with poor grafting ability in terms of Li surface compaction and SEI stabilization.
