Abundant and inexpensive sodium metal anode with low redox potential and high theoretical capacity shows great potential in next-generation high-energy–density energy storage batteries. However, the uncontrollable growth of sodium dendrites during cycling decays cell cycle life, limiting the practical application and large-scale production of sodiu...

Herein, a novel hollow rod-like composite was obtained by doping nitrogen-doped carbon quantum dots (NCDs) into covalent organic frameworks (COFs) (NCDs@COFBTH-TT) by a one-pot hydrothermal method. Such a hollow structure not only facilitates the transport of Li⁺ but also exposes a large number of active sites. The doped NCDs improve the electrical...
The demand for practical implementation of lithium metal batteries (LMBs) is increasing due to their superior energy density. However, poor cycle life and safety concerns regarding dendrite formation remain significant challenges. Recent studies have shown empirical improvements in cycle life through the use of high‐rate discharge protocols, but th...
Traditional challenges of poor cycling stability and low Coulombic efficiency in Zinc (Zn) metal anodes have limited their practical application. To overcome these issues, this work introduces a single metal‐atom design featuring atomically dispersed single copper (Cu) atoms on 3D nitrogen (N) and oxygen (O) co‐doped porous carbon (CuNOC) as a high...
In this study, we synthesized standing 2D δ‐Cu2Te flakes (δ‐CTFs) via a facile post‐tellurization process, which served as the current collector to accommodate zinc (Zn) for AZIBs. These flakes exhibited low nucleation overpotential and low interfacial impedance, facilitating the plating/stripping of Zn ions. Interestingly, the hydrophilicity and s...

As emerging energy storage devices, sodium‐ion batteries (SIBs) are perceived as promising alternatives to lithium‐ion batteries (LIBs) due to their low cost and high safety. The cathodic side plays a crucial role in determining the energy density as well as the service life of SIBs, and the polyanionic cathode materials are featured by excellent cycle stability, flexible operating voltage and suitable overall electrochemical properties. However, the intrinsic inferior electronic conductivity limits their rate performance. Recently, the possibility of employing advanced electrospinning techniques to fabricate polyanionic materials has been explored. The facile electrospinning can greatly facilitate the ionic and electronic conduction of cathodes by constructing three‐dimensional (3D) conductive networks with the one‐dimensional (1D) nanofibers, and thus improves their electrochemical performance. In this review, we summarize the research progress of the electro‐spun polyanionic cathodic materials and their applications in SIBs, and present future prospects as well as challenges of the electro‐spun polyanions faced to the ever‐increasing demand of advanced energy storage.
