Application of MXenes in lithium-sulfur batteries

Design principles for 2D transition metal dichalcogenides toward lithium−sulfur batteries

“…To address these intractable issues pertaining to Li–S batteries, two-dimensional (2D) materials have been utilized for their intriguing feature, including graphene, 9 hexagonal boron nitride, 10 MXene, 11 and transition metal dichalcogenides. 12 Among them, transition metal dichalcogenides (TMDs) have triggered great interest in recent years as a promising branch.…”

Porous N-Doped Carbon Decorated with Atomically Dispersed Independent Dual Metal Sites from Energetic Zeolite Imidazolate Frameworks as Bidirectional Catalysts for Lithium–Sulfur Batteries

“…Lithium–sulfur (Li–S) batteries are considered to be promising energy storage systems with great development prospects owing to their high theoretical specific capacity (1675 mA h g –1 ) and theoretical energy density (2600 W h kg –1 ). In addition, compared with traditional lithium-ion batteries, abundant reserves in nature and the environmental friendliness of sulfur attract the widespread attention of researchers. − Despite these advantages, the poor electronic and ionic conductivity of sulfur, the shuttle effect of lithium polysulfides (LiPSs), and the slow redox kinetics (leading to rapid capacity decay, low Coulombic efficiency, and inefficient use of sulfur) are still serious challenges for the practical application of Li–S batteries. , …”
