Metal Atom-Decorated Carbon Nanomaterials for Enhancing Li-S/Se Batteries Performances: A Mini Review

“…The noble metals, such as Au (Babu et al, 2015;Zhang et al, 2020), Pt (Al Salem et al, 2015Qu et al, 2018;Liu et al, 2019), and Pd (Ma et al, 2019), etc., when combined with the conductive carbon substrates, commonly demonstrate superior catalytic properties on LiPS redox reactions.…”

“…The Au NPs with high conductivity can significantly control the deposition of the trapped LiPSs, contributing to the uniform distribution of sulfur species upon charging/discharging. Recently, Liang et al reported a yolk-shell Au@microporous carbon nanosphere with the synergistic advantages of a hollow nanosphere and functional Au nanoparticles (Zhang et al, 2020), which also contributed to a high specific capacity, and good electrochemical activities and reaction kinetics of Li-S batteries. While Zuo's group skillfully imbedded palladium nanoparticles in hollow carbon spheres as the sulfur host.…”

Applications of transition-metal sulfides in the cathodes of lithium–sulfur batteries

“…In order to increase the sulfur loading and inhibit the dissolution of LiPSs into the electrolyte, carbon materials with meso-or micro-pores and multi-channel morphology were once used to physically limit the movements of LiPSs but failed to obtain satisfactory performance. Then, the polar nature of LiPSs was further utilized by constructing a polar surface on cathode materials to improve the adsorption of LiPSs, with additives or matrixes such as metal oxides [40][41][42][43], noble metals [44,45], metal carbides [46,47], N-doped carbon [48][49][50], polymers [51][52][53] and TMSs.…”

High electrochemical performance small grain size vanadium pentoxide prepared by hydrothermal method and as high proportion sulfur supported matrix materials for lithium‐sulfur batteries

“…At present, new energy materials have been widely concerned by many researchers due to lack of fossil energy and environmental damage. At the same time, the popularity of electric vehicle and hybrid electric vehicle promotes the rapid development of energy storage and supply systems such as lead‐acid batteries, lithium‐ion batteries, lithium‐sulfur batteries, lithium oxygen batteries and so on 1‐6 . Among these, lithium‐ion batteries owing to their high energy densities and long cycle life have been one of the most promising energy storage systems and extensively applied in the field of the electric vehicle.…”
