Interlayer design based on carbon materials for lithium–sulfur batteries: a review

Abstract

This review summarizes recently developed Li–S batteries with novel interlayers based on carbon materials.

Covalent Organic Frameworks for Next‐Generation Batteries

“…Currently, lithium-sulfur batteries (LSBs) that are environmentally friendly and low cost and exhibit a high theoretical capacity (1672 mAh g À 1 ) and energy density (2600 Wh kg À 1 ) are being studied by increasing numbers of research teams. [64][65][66] However, lithium-sulfur batteries also have many problems, such as the low conductivity of sulfur and the shuttle effect of polysulfides. Besides, the difference between the densities of Li 2 S (1.66 g cm À 3 ) and sulfur (2.03 g cm À 3 ) will cause the electrode volume to change, resulting in rapid capacity decay.…”

Interconnected NiCo2O4 nanosheet arrays grown on carbon cloth as a host, adsorber and catalyst for sulfur species enabling high-performance Li–S batteries

“…In respect of the three major issues of electrical insulation, volume change, and polysulfide loss, porous carbon materials physically confining sulfur are proposed [21][22][23] . However, the weak physical interactions between non-polar carbon materials and polar LiPS is difficult to effectively inhibit the shuttle effect [24][25][26] . hydrothermal reaction, the co-precipitation of Ni 2+ , Co 2+ and the OH -(originated from hexamethylenetetramine), as well as the decomposition of CH 3 OH, produced the precursor, which has a composition similar to (Ni x Co y )(OH) a (CO 3 ) b (H 2 O) c and morphology resembling that of the NiCo 2 O 4 nanosheets (Fig.…”

Application of Carbon Nanotube-Based Materials as Interlayers in High-Performance Lithium-Sulfur Batteries: A Review

“…Some reviews also discussed recent developments on the interlayer materials for Li-S batteries. For instance, Chen et al reviewed on interlayer design of Li-S batteries by coating and inserting different types of carbon-based materials (Chen L. et al, 2020). Furthermore, Jiao et al reviewed recent articles regarding to the interlayers for Li-S batteries including carbon-based interlayers (Jiao et al, 2019); Pang and co-workers reviewed on recent research work on CNT-based materials for Li-S batteries (Zheng et al, 2019).…”
