A Comprehensive Review of Materials with Catalytic Effects in Li–S Batteries: Enhanced Redox Kinetics

Abstract: Lithium–sulfur batteries (LSBs) are cost‐effective and high‐energy‐density batteries. However, the insulating nature of active materials, the shuttle effect, and slow redox kinetics lead to severe capacity decay and low rate capabilities. Numerous multimodal approaches have been attempted to tackle these issues and have pushed the cycle stability and energy density to higher levels. Recently, accelerating the redox kinetics using catalytic materials has been considered as a means to realize high‐performance LS… Show more

“…Atomic‐scale electrocatalysts in Li–S batteries are strongly considered to enhance redox kinetics of sulfur conversion, as the atomically dispersed active sites on substrates can maximize the atom‐utilization efficiency for sulfur species modulation and curtail inert dosage in electrodes . Single cobalt and iron atoms coordinated with nitrogen have been explored as electrocatalysts to enhance kinetic conversion from LiPSs to Li 2 S and mitigate LiPS shuttle.…”

“…Atomic-scale electrocatalysts in Li-S batteries are strongly considered to enhance redox kinetics of sulfur conversion, as the atomically dispersed active sites on substrates can maximize the atom-utilization efficiency for sulfur species modulation and curtail inert dosage in electrodes. 47 Single cobalt [48][49][50][51] and iron 52,53 atoms coordinated with nitrogen have been explored as electrocatalysts to enhance kinetic conversion from LiPSs to Li 2 S and mitigate LiPS shuttle. However, kinetic understanding of the electrocatalytic capabilities of atomic electrocatalysts for Li-S batteries is rather limited, yet critically important to rational design of high-efficiency electrocatalysts in Li-S batteries.…”

“…Recently, transition metal nitride (e.g., TiN, VN, and MoN) have been used as anchoring materials because of the high conductivity and strong chemical adsorption for polysulfides . However, polysulfides transformation and Li 2 S precipitation behaviors were not investigated in these works, which is of great significance for enhancing the utilization of sulfur and improving the energy density of the batteries . Yang et al demonstrated that the TiO 2 ‐TiN heterostructures loaded on the separator possess favorable electrocatalysis ability to accelerate polysulfides transformation .…”
