“…96 At the electrode scale, electrolyte flow and the highflux Li + diffusion are made possible by the 3D robust fibrous nanostructure, which also preserves electrode reliability during large volume changes of active sulfur as well as in mechanical abuse conditions. 97 To make a substantial advancement in the electrode's electrical conductivity, a self-assembled 3D 3DNG/TiN composite is presented as a self-supporting electrode for LSBs. The 9.6 mg cm À2 sulfur mass loading has been considered feasible by 3DNG/TiN composite, and the 3DNG cathode produces a 12.0 mAh cm À2 extremely high areal capacity at 8.03 mA cm À2 high current density.…”

The creation of effective and clean energy storage technologies has advanced dramatically due to growing worldwide worries over the depletion of fossil fuels and environmental issues. Energy storage and conversion systems have emerged as a crucial component with the development of numerous electronic devices, enabling the devices to function for extended periods of time. Due to their enormous surface area, strong electrical conductivity, and ion transport, 3D self‐supported nanoarchitectures associated with electrochemical energy storage (EES) devices can offer alternatives for enhancing the performance and advancement of existing EES systems. Here, we present the results of our findings regarding the design, production, and use of self‐supported 3D nanostructures in energy storage and conversion systems such as supercapacitors, batteries, solar cells, and fuel cells. A variety of advanced 3D nanomaterials may be readily created on an immense scale using various synthetic techniques, and they have a great deal of potential for use as electrodes in energy storage and conversion devices with much better performance. These fabrication techniques include electrochemical deposition, electrospinning, chemical precipitation, spray pyrolysis, sol‐gel method, hydrothermal method, chemical vapor deposition, and so forth.

“…For example, combining 3D flame-retardant materials with sulfur or replacing polyvinylidene fluoride (PVDF) with an aqueous binder can export heat in time and block the molten sulfur at the cathode to improve its safety. 34–39 Furthermore, electrolyte additives and ionic liquids (ILs) with a flame-retardant effect can capture free radicals and realize a gas-phase flame-retardant effect via their elements P and N. 40–44 A composite gel electrolyte with good flexibility can prevent lithium dendrites from penetrating the separator and the flame-retardant group in its macromolecular chain can extinguish the flame when it is on fire. Furthermore, flame-retardant coating layers and an intrinsic flame-retardant electrospinning separator can improve the safety of the separator, the spread of flame and heat can be blocked by the coating layers, and separators with a porous structure can not only capture LiPSs but also realize condense-phase flame retardancy via electrospinning.…”

Lithium–gas batteries (LGBs) have garnered significant attention due to their impressive high‐energy densities and unique gas conversion capability. Nevertheless, the practical application of LGBs faces substantial challenges, including sluggish gas conversion kinetics inducing in low‐rate performance and high overpotential, along with limited electrochemical reversibility leading to poor cycle life. The imperative task is to develop gas electrodes with remarkable catalytic activity, abundant active sites, and exceptional electrochemical stability. Electrospinning, a versatile and well‐established technique for fabricating fibrous nanomaterials, has been extensively explored in LGB applications. In this work, we emphasize the critical structure–property for ideal gas electrodes and summarize the advancement of employing electrospun nanofibers (NFs) for performance enhancement in LGBs. Beyond elucidating the fundamental principles of LGBs and the electrospinning technique, we focus on the systematic design of electrospun NF‐based gas electrodes regarding optimal structural fabrication, catalyst handling and activation, and catalytic site optimization, as well as considerations for large‐scale implementation. The demonstrated principles and regulations for electrode design are expected to inspire broad applications in catalyst‐based energy applications.
