“…The cell with the MgO/PDAAQ/S revealed a small Rct value of 17.0 ohm, which did not grow as much as that of the cell with the PDAAQ/S, with a higher Rct value of 27.8 ohm after 500 cycles. The lower Rct of the MgO/PDAAQ/S cell indicates a faster ion and electron transfer at the cathode–separator interface, which is attributable to the higher contact area between the electrolyte and the conductive structure. − It was found that the MgO/PDAAQ had a strong ability to capture and reuse polysulfides and allowed for fast charge and lithium-ion transport even after 500 cycles.…”

A lithium-sulfur battery with a low cost, a long cycle life, safety, and high gravimetric energy density may be a viable option for overcoming the charge-storage limitations of lithium-ion batteries. This research describes how to increase the cycle life and performance of lithium-sulfur batteries by using highly conductive and lightweight cathode materials composed of poly(1,5diaminoanthraquinone) (PDAAQ) and non-stoichiometric magnesium oxide nanoparticles (MgO). The cell with the MgO/ PDAAQ/S cathode has a discharge capacity of 1239 mA h g −1 after 200 cycles. The discharge capacity is maintained at 1020 mA h g −1 after 500 cycles. When considering non-stoichiometric MgO, which is oxygen-rich, the adsorption energy of Li becomes highly negative (−4.648 eV/Li atom), making the structure active for adsorption of lithium polysulfide chains. The novel combination of a MgO/PDAAQ/S cathode has a significant potential for the fabrication of high gravimetric energy density Li−S batteries (570 W h kg −1 per cell) over 200 cycles.

“…During the discharge process, the electrochemical reaction of the sulfur cathode involves the reaction of polysulfide intermediates with slow kinetics, which is further slowed down under harsh practical working conditions. To conquer these challenges, especially the impact of the shuttle effect on the cycle life of Li−S batteries, researchers have made numerous efforts in the design of electrode structures, modulation of the electrolyte, separator modification, and the reaction mechanism of the battery [33–38] . As one of the core inner components of the battery, the separator has been a hotspot of research by scholars.…”

Lithium‐sulfur (Li−S) batteries have great potential for the development of next‐generation high‐energy‐density secondary batteries owing to their high theoretical energy density, active material (sulfur) environmental friendliness, and low cost. However, their application is still impeded by the inherent sluggish kinetics and solubility of intermediate products of the sulfur cathode. Interface design is an important direction to address challenges in the development of Li−S batteries. The modification of the separator has been shown to effectively suppress the shuttling effect of physical hindrance or chemical bonding without affecting the utilization of active materials. This review encompasses the application of nanostructured transition metal oxides (TMOs), transition metal sulfides (TMSs), transition metal nitrides (TMNs), transition metal phosphides (TMPs), such as incorporating functional separators beyond the approach for preparing novel cathodes, and discusses their composites in a new multifunctional barrier layer for Li−S batteries. The objective properties of various metal compounds and the effect of the shuttle effect in particular on the electrochemical performance in Li−S batteries are highlighted, and give an outlook on the promising approaches for the construction of reliable Li−S batteries.

“…Lithium–sulfur (Li–S) batteries are a potential alternative to Li-ion batteries. However, there are some challenges in developing Li–S batteries, such as lower conductivity due to the insulating nature of sulfur, capacity fading, low mass loading of sulfur, and the shuttle effect. − Next-generation rechargeable batteries based on zinc (Zn), magnesium (Mg), calcium (Ca), and aluminum (Al) are the most promising options. The Zn batteries can be constructed from readily available materials, are less expensive than Li-ion batteries, and have a longer service life.…”

Lithium-free metal batteries are currently emerging as a viable substitute for the existing Li-ion battery technology, especially for large-scale energy storage, ease of problems with lithium availability, high cost, and safety concerns. However, the economic benefits of lithium-free batteries, which are often mentioned, have not been studied in detail until recently. This paper aims to bridge the gap between academics and industry by advocating the best practices for measuring performance and proposing recommendations concerning essential parameters, including capacity, cyclability, Coulombic efficiency, and electrolyte consumption in novel lithium-free batteries. Here, the monovalent, divalent, and multivalent lithium-free metal batteries are investigated. Finally, the technology roadmap of these battery technologies and their current applications, commercialization, and future technologies are discussed to open a window for promoting the commercial application of lithium-free metal batteries.
