“…Owing to its unique properties graphene found application in various fields, including electronics [57], photonics [58], energy storage and conversion [59], sensors [60], bio-application [61], microwave adsorption [62,63], catalysis [64], photo-catalysis [65] and environment [66]. Graphene is recognized as an excellent material for preparation of cathodes for Li-S batteries providing high surface area, porous and electrically conductive matrix for immobilization of large sulfur amount and suppression of the LiPSs shuttle effect due to physical and chemical interaction with LiPSs [67]. However, despite the undeniable advantages of using 2D graphene in Li-S battery technology, researchers are still concerned about low trapping ability of the 2D graphene sheets to LiPSs due to its open structure, agglomeration tendency resulting in reduction of the specific surface area and dielectric constant and increase in the interface polarization and π-electron stacking on the basal plane which is not electrochemically active, thus making charge transfer not favorable [68].…”

“…Carbon-based materials are added to LSBs primarily to improve the redox kinetics of soluble long-chain polysulfides into insoluble short-chain polysulfides to mitigate the shuttle effect and improve the battery’s rate capability [ 111 , 112 , 113 , 114 ]. Carbon materials, such as graphene oxide (GO), with highly polar or electronegative functional groups can also electrostatically repel LiPS.…”

Lithium-Sulfur batteries (LSBs) are one of the most promising next-generation batteries to replace Li-ion batteries that power everything from small portable devices to large electric vehicles. LSBs boast a nearly five times higher theoretical capacity than Li-ion batteries due to sulfur’s high theoretical capacity, and LSBs use abundant sulfur instead of rare metals as their cathodes. In order to make LSBs commercially viable, an LSB’s separator must permit fast Li-ion diffusion while suppressing the migration of soluble lithium polysulfides (LiPSs). Polyolefin separators (commonly used in Li-ion batteries) fail to block LiPSs, have low thermal stability, poor mechanical strength, and weak electrolyte affinity. Novel nanofiber (NF) separators address the aforementioned shortcomings of polyolefin separators with intrinsically superior properties. Moreover, NF separators can easily be produced in large volumes, fine-tuned via facile electrospinning techniques, and modified with various additives. This review discusses the design principles and performance of LSBs with exemplary NF separators. The benefits of using various polymers and the effects of different polymer modifications are analyzed. We also discuss the conversion of polymer NFs into carbon NFs (CNFs) and their effects on rate capability and thermal stability. Finally, common and promising modifiers for NF separators, including carbon, metal oxide, and metal-organic framework (MOF), are examined. We highlight the underlying properties of the composite NF separators that enhance the capacity, cyclability, and resilience of LSBs.

“…Graphene and CNTs having high crystallinity, electronic mobility, and importantly high thermal conductivity, are uniquely suited for energy storage applications. It should be mentioned that although the applications of carbon nanostructures in energy storage and conversion have been reviewed on several occasions in the past few years, [ 3,10,45–65 ] it is a rapidly evolving and highly active field, and the vast amount of research carried out worldwide has accumulated very quickly. Moreover, the present status of the state‐of‐the‐art design of carbon‐based pure/doped/hybrid nanomaterials, their functionalities with a better in‐depth understanding of materials, as well as their interfaces and phenomena occurring therein, can help design novel next‐generation batteries, supercapacitor or hybrid devices with new applications.…”

Carbon-based nanomaterials, including graphene, fullerenes, and carbon nanotubes, are attracting significant attention as promising materials for next-generation energy storage and conversion applications. They possess unique physicochemical properties, such as structural stability and flexibility, high porosity, and tunable physicochemical features, which render them well suited in these hot research fields. Technological advances at atomic and electronic levels are crucial for developing more efficient and durable devices. This comprehensive review provides a state-of-the-art overview of these advanced carbon-based nanomaterials for various energy storage and conversion applications, focusing on supercapacitors, lithium as well as sodium-ion batteries, and hydrogen evolution reactions. Particular emphasis is placed on the strategies employed to enhance performance through nonmetallic elemental doping of N, B, S, and P in either individual doping or codoping, as well as structural modifications such as the creation of defect sites, edge functionalization, and inter-layer distance manipulation, aiming to provide the general guidelines for designing these devices by the above approaches to achieve optimal performance. Furthermore, this review delves into the challenges and future prospects for the advancement of carbon-based electrodes in energy storage and conversion.
