“…Recently, the addition of inorganic salts, such as CsNO 3 , KNO 3 , La(NO 3 ) 3 , and Zn(CH 3 COO) 2 , has been successfully applied in electrolytes of Li-S batteries to enhance the reversibility of the Li metal anode, due to either the electrostatic shield effect or the formation of transition metal/lithium sulfides in the SEI layers. [81][82][83][84][85] Some other surface-charged inorganic nanoparticles, such as montmorillonites, are also found to have the ability to facilitate uniform Li deposition by regulating the near-surface Li ion distribution. 86,87 Suitable additives in electrolytes can also help prevent irreversible polysulfide loss and improve the utilization of sulfur.…”

With the merits of low cost, abundant resources, environment friendliness, and high energy density, the Li-S battery is recognized as a promising alternative to the Li ion battery and is anticipated to play an important role in high-energy-density electrochemical storage systems. In this review, we first review the development process of Li-S batteries and briefly introduce the working principle of Li-S batteries. The scientific problems existing in the Li-S batteries, such as sulfur cathode, separator, electrolyte, and Li anode, and the corresponding countermeasures, are then summarized. Subsequently, main research advancements of Li-S batteries are comprehensively reviewed, and the critical concerns about commercialization of Li-S batteries are discussed. Finally, we give our perspectives on the development of high-performance Li-S batteries. We hope this review can provide the timely and comprehensive information on the future research direction of Li-S batteries and offer the guidance for material design and structure optimization of Li-S batteries.

Nowadays, batteries for electric vehicles are expected to have a high energy density, allow fast charging and maintain long cycle life, while providing affordable traction, and complying with stringent safety and environmental standards. Extensive research on novel materials at cell level is hence needed for the continuous improvement of the batteries coupled towards achieving these requirements. This article firstly delves into future developments in electric vehicles from a technology perspective, and the perspective of changing end-user demands. After these end-user needs are defined, their translation into future battery requirements is described. A detailed review of expected material developments follows, to address these dynamic and changing needs. Developments on anodes, cathodes, electrolyte and cell level will be discussed. Finally, a special section will discuss the safety aspects with these increasing end-user demands and how to overcome these issues.

“…The formed La 2 S 3, together with Li 2 S 2 /Li 2 S and Li x SO y constitute the passivation film on the surface of Li metal, leading to obvious improvement in the electrochemical performance. Zeng et al have investigated the effect of additives of transition metal cations on Li-S batteries (Zeng et al, 2019). The results suggest that some transition cations especially Zn cations exhibit a positive effect on enhancing rate capability and Coulombic efficiency of Li-S batteries.…”

“…Safety is the most critical factor when it comes to the daily usage and commercialization of Li-S batteries. The enhancement of safety of Li-S batteries can be achieved by modifying metal anodes (Xu et al, 2014;Lin et al, 2017), optimizing cathode materials (Wang et al, 2015;Cleaver et al, 2018), designing new separators (Chung et al, 2015;Ma et al, 2016;Li M. et al, 2018;Wang et al, 2019), selecting suitable electrolyte Judez et al, 2017;Liu et al, 2018), adding additives (Liu et al, 2016;Zeng et al, 2019) related discussions can be found in the above sections. Here, we mainly discuss safety involving the choice of solvent and the recycling of lithium.…”

With the increasing demand for green energy due to environmental issues, developing batteries with high energy density is of great importance. Li-S batteries, since their big breakthrough in 2009, have attracted much attention in both academia and industry. In academia, significant progress has been made in improving the specific capacity, rate capacity, and cycle performance using various novel strategies. However, the performance is hugely different when these strategies are extended to mass production, indicating a significant difference between academic research, and industrial production. In this brief review, we discussed the gap between the academic research and commercialization in detail based on literature reports and to our more than 10 years' experience on Li-S pouch cells, which including cathodes, anodes, separators, interlayers, electrolytes, and additives. The problems, which existing in pouch cells by using the materials and technologies developed by academic research using coin cells, was analyzed. We expected that this review could be helpful to both academic research and industrial commercialization of Li-S batteries.
