“…Jiao et al synthesized another multifunctional binder (AHP), with abundant amide groups as an efficient binder for Li–S batteries . The polar AHP binder prepared by polymerization of HDI with ethylenediamine (EDA) contains a large amount of amino groups, which can strongly anchor the polysulfides, thus suppressing the shuttle effect.…”

Lithium-sulfur batteries are regarded as promising candidates for energy storage devices due to their high theoretical energy density. Various approaches are proposed to break through the obstacles that are preventing Li-S batteries from realizing practical application. Recently, the importance of the strong chemical interaction between polar materials and polysulfides is recognized by researchers to improve the performance of Li-S batteries, especially with respect to the shuttle effect. Polar materials, unlike nonpolar materials, exhibit strong interactions with polysulfides without any modification or doping because of their intrinsic polarity, absorbing the polar polysulfides and thus suppressing the notorious shuttle effect. The recent advances on polar materials for Li-S batteries are reviewed here, especially the chemical polarpolar interaction effects toward immobilizing dissolved polysulfides, and the relationship between the intrinsic properties of the polar materials and the electrochemical performance of the Li-S batteries are discussed. Polar materials, including polar inorganics in the cathode and polar organics as binder for the Li-S batteries are respectively described. Finally, future directions and prospects for the polar materials used in Li-S batteries are also proposed.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201707520. and iii) high solubility of lithium polysulfide (Li 2 S n ) species in the organic electrolytes and the related "shuttle effect" lead to severe capacity fading, which is obstructing their practical application. [5][6][7][8][9] Tremendous efforts have been devoted to the complex problems listed above. In particular, early research was focused on the incorporation of sulfur into nonpolar carbon-based materials, including porous carbon, hollow carbon spheres, carbon nanotubes, graphene, and graphene oxide. [10][11][12][13][14][15][16][17][18][19][20][21][22][23] The introduction of carbonbased materials serving as sulfur hosts could effectively ameliorate the issue of poor electrical conductivity and volume expansion during the charge-discharge process. On the other hand, in terms of chemical structure, polarity of molecule refers to a separation of electric charge, which results in an electric dipole or multipole in a molecule or its chemical groups. Because of the difference in electronegativity between the bonded atoms, the polar bonds must exist in the polar molecules. The polar molecules could interact through dipole-dipole intermolecular forces and hydrogen bonds. In general, the chemical interaction between two kinds of the polar molecules is much stronger than that between a polar molecule and a nonpolar molecule. The Li 2 S n species belong to the class of polar molecules, while the carbon hosts are assigned to the nonpolar materials. Therefore, the conjugate nonpolar carbon planes have limited sites to strongly anchor Li 2 S n species, resulting in weak interaction between the carbonbased materi...

Currently, apart from the widely known lithium-ion batteries, there are competitive solutions in the form of, for example, Li-S batteries. While the results of studies on the toxicity of Li-ion battery components are published, such studies on the components of Li-S cells are just beginning. The purpose of the current review was to identify materials used in the production of Li-S batteries and their toxicity, especially for humans. The review showed many kinds of materials with different levels of toxicity utilized for manufacturing of these cells. Some materials are of low toxicity, while some others are of the high one. A lot of materials have assigned different hazard statements. For some of the materials, no hazard statements were assigned, although such materials are toxic. No data related to the toxicity of some materials were found in the literature. This points out the need to further studies on their toxicity and legal actions to assign appropriate hazard statements.

“…As a single polymer binder may not well meet all the requirements to boost the performance of Li-S batteries and build the high sulfur loading electrode, many researchers tried to combine different binders together in the cathode [105][106][107] . For example, Huang and co-workers designed a gelatin and PEI composite (GPC) binder with a simple mixing process [108] .…”
