“…[11][12][13] The high theoretical capacity depends on the reversible lithiation process using lithium polysulfides (LPS, chemical formula: Li 2 S x , 4 ≤ x ≤ 8) as intermediates, 14,15 but this chemical reaction will be accompanied by a large volume expansion, resulting in cathode cracking and the loss of active materials. [16][17][18] The hollow cavity between core and shell can effectively buffer the volume expansion and improve the electrochemical performance.…”

“…Lithium–sulfur (Li–S) batteries are considered promising energy storage technologies because of their high theoretical capacity (1675 mAh g –1 ), environmental friendliness, and economic benefits. , However, several challenging issues of Li–S batteries associated with poor electronic conductivity of S, the shuttle effect of polysulfides (LiPS), and sluggish transformation process of LiPS result in unsatisfactory capacity and cycle life, severely hindering their practical application. − Encapsulating S into a porous carbon host can effectively improve the electronic conductivity of the S cathode, which is suitable for large-scale applications. − However, the weak interaction between nonpolar carbon and S or LiPS hardly restricts LiPS shuttling, leading to low sulfur utilization and poor electrochemical performance. Many strategies, such as introducing various polar transition metal compounds − and metal nanoparticles , into the S cathode, have been widely developed to anchor S and block the leaching of LiPS. Nevertheless, these methods involve a complicated, high temperature synthetic process or expensive reagents.…”

Lithium−sulfur (Li−S) batteries are considered promising energy storage technologies due to their high energy density and environmental friendliness. However, the unsatisfactory electrochemical performance mainly caused by dissolution and shuttling of polysulfides limits their application. Herein, a multifunctional separator, i.e., the sodium alginate (SA) fiber membrane with in situ loading of ZIF-67 attached on the polyacrylonitrile (PAN) matrix (ZIF-67/SA-PAN), is developed for Li−S batteries. On the basis of the synergistic adsorption and catalytic effect, ZIF-67/SA-PAN can inhibit the shuttling of polysulfides and promote fast transformation of the intercepted polysulfides, as revealed by in situ characterization and theoretical calculations. The ZIF-67/SA-PAN separator endows Li−S batteries with high reversible capacity (e.g., 797.4 mAh g −1 with a high sulfur loading of 5.45 mg cm −2 at 0.1 C) and long cycle life (500 cycles at 1 C). The ZIF-67/SA-PAN functional separator in this work can provide a facile and inexpensive approach to fabricate practical Li−S batteries.

Room‐temperature sodium–sulfur (RT‐Na/S) batteries are emerging as promising candidates for stationary energy‐storage systems, due to their high energy density, resource abundance, and environmental benignity. A better understanding of RT‐Na/S batteries in the view of the whole battery components is of essential importance for fundamental research and practical applications. In particular, the components other than sulfur cathodes in preventing the migration of polysulfides and accelerating the reaction kinetics have been greatly overlooked. Such a biased research trend is also adverse to the broader applications for RT‐Na/S batteries, which have long been ignored in previous reviews. Herein, approaches to the historical progress toward practical RT‐Na/S batteries through a “teamwork” perspective are comprehensively summarized, and balanced research trends are encouraged to enable practical RT‐Na/S batteries. In the meantime, the persisting issues, promising solutions, and practical applications of advanced sulfur host design, Na metal anode protection, electrolyte optimization, separator modification, and binder engineering are clearly emphasized. Finally, the device‐scale evaluation in practical parameters and advanced characterization tools are thoroughly provided. This review aims to provide the “teamwork” perspective on the whole‐cell design and fundamental guidelines that can shed light on research directions for practical RT‐Na/S batteries.
