“…[170] A smooth and compact surface layer, making up of inorganic species such as LiN x O y and organic species such as ROLi and ROCO 2 Li, can prevent the parasitic reaction between Li anode and LiPSs. Except for Li + cation, nitrates comprised of other cations were served as additives, such as CsNO 3 , [171] KNO 3 , [172] and ZrO(NO 3 ) 2 , [173] where oxidative NO 3 ion always plays a role in reinforcing SEI layer on the surface of Li metal anode, and the cations have their special functions. For example, Jia et al verified that further growth of Li dendrites can be delayed by the electrostatically attracted K + cations from the KNO 3 additive.…”

Lithium–sulfur (Li–S) batteries are regarded as the most promising next‐generation energy storage systems due to their high energy density and cost‐effectiveness. However, their practical applications are seriously hindered by several inevitable drawbacks, especially the shuttle effects of soluble lithium polysulfides (LiPSs) which lead to rapid capacity decay and short cycling lifespan. This review specifically concentrates on the shuttle path of LiPSs and their interaction with the corresponding cell components along the moving way, systematically retrospect the recent advances and strategies toward polysulfides diffusion suppression. Overall, the strategies for the shuttle effect inhibition can be classified into four parts, including capturing the LiPSs in the sulfur cathode, reducing the dissolution in electrolytes, blocking the shuttle channels by functional separators, and preventing the chemical reaction between LiPSs and Li metal anode. Herein, the fundamental aspect of Li–S batteries is introduced first to give an in‐deep understanding of the generation and shuttle effect of LiPSs. Then, the corresponding strategies toward LiPSs shuttle inhibition along the diffusion path are discussed step by step. Finally, general conclusions and perspectives for future research on shuttle issues and practical application of Li–S batteries are proposed.

“…Researchers explored the specific reaction of lithium-ion batteries fire include decomposition and mutual reaction between SEI (solid electrolyte interphase) layers, electrolyte, anode material and cathode material, and a systematic theoretical analysis has been carried out in the relevant key links for solving the problem of battery safety. [5][6][7] Adequate measures have been explore to achieve considerable 'intrinsic safety', like improving the thermal stability of battery separators, 8 optimizing composition of the SEI layer to make battery dendrite-free and life longer, 9 developing flame-retardant additives to lower the flammability of liquid electrolytes, 10 finding or synthesizing intrinsically nonflammable electrolytes. 11 All these studies are focused on solving the early risk of thermal runaway of lithium-ion batteries, in order to prevent the combustion and explosion as much as possible, but 'completely intrinsic security' still has a long way to go.…”

“…In detail, in symmetric batteries, PS conversion is boosted with the aid of STLC effect (Figure 2c). Once the only active material Li 2 S 8 adds to ether electrolyte, STLC effect offers extra push on PS conversion, exhibited as a large broad peak (in DCC case, the dark cyan line in Figure 2c) splitting into two separate peaks (in DCC+STLC case, the orange line in Figure 2c), which can be considered as a two-step reaction at AE0.3 and AE0.5 V. Besides, STCL effect turns the reversible long-chain PS relating redox into specific steps in overall S 8 ↔ Li 2 S x ↔ Li 2 S conversion, [27,28] implying enhanced kinetics of short-chain PS conversion to some degree.…”

on demand of high energy density, electrolytewetted interfaces slump. [5,6] Therefore, all interface-dependent processes, especially Li 2 S x (x ≤ 4) reduction, are exacerbated, [7][8][9] and a bluff attenuation of capacity will definitely show up after a few cycles. [10][11][12] In order to promote the electrochemical reactions at leanelectrolyte condition, modulating both transfer pattern and gathering pattern of ions (PS and Li + ) is an indispensable assistance, at least making PS migrate toward cathode preferentially, rather than shuttle.Prelithiation is proved to be effective in Coulombic efficiency increasing [13,14] and resistance decreasing. [12] Thereinto, direct lithium implantation in cathodes facilitates an even lithium dispersion. However, a reaction happened in LSB not only needs lithium enrichment, but also requires the participation of PS. Recent publications point out that O doping [15][16][17] and O vacancies [18,19] are specialized in PS affinities. Moreover, the high electronegativity of O-containing centers endows S cathode with improved electrolyte compatibility. [20,21] Inspired by those scientific results, we propose a strategy to boost LSB running in lean electrolyte. Providing that implanting some O-relevant electrolyte-philic species at sites adjacent to those lithium-contained zones, Li + and PS will appear side by side at one wetted interface and therefore lowering down the dependence of electrochemical reactions on the restricted ion transfer. In this work, direct lithium implant and Ocontaining site introduction are simultaneously realized by one chemical, lithium polyacrylic acid (LiPAA). Results and DiscussionActually, Mukra et al. [22] published a paper about LiPAA as a cathode binder in LSBs. It was synthesized by lithium hydroxide reacting with polyacrylic acid of 450,000 in molecular weight. Thanks to its longchain anion, the resulted LiPAA performs a satisfying substitution of PVDF, deserving function-plus binder for its extra supply of Li + . Comparing its Li 2 S 4 adsorption potential to that of a short-chain LiPAA, specially designed in our research, whose molecular weight is only ~2000 (Figure 1a), it is definite that LiPAA containing short-chain anion wins out, of course, the short-chain PAA do the same thing (Figure S1).
