“…This innovative design enhanced the rate performance of the hard carbon anode. Zhao et al [ 131 ] added crown ether additives into the carbonate electrolyte. The results of the Fourier spectral transform infrared spectroscopy showed the characteristic peaks of the crown ether coordination compounds (837 cm −1 ) ( Figure c), which proved that the oxygen on the ether ring could coordinate with Na + to form a coordination compound that reaches the hard carbon surface and alters the SEI film (Figure 11a).…”

With the rapid development of renewable energy and the growth of energy demand, sodium‐ion batteries have attracted much attention from researchers as a promising energy storage technology. Hard carbon anodes are considered to be the most promising anodes of sodium‐ion batteries because of their low sodium storage potential, high capacity, wide range of raw materials, and environmental friendliness. However, the rate capability and initial coulombic efficiency of hard carbon hinder the further commercialization of hard carbon. This review provides a concise overview of the three microstructures and four sodium storage mechanisms of hard carbon and comprehensively introduces the latest research progress on strategies to effectively improve the electrochemical performance of hard carbon anodes, which are categorized into structural and morphology design, precursors selection, electrolyte optimization, surface engineering and pre‐sodiation as modification strategies. In addition, we also encapsulate the current research progress on sodium‐ion full batteries and look forward to the developmental prospects of hard carbon anodes in sodium‐ion batteries.This article is protected by copyright.

“…GCD can also be adapted to probe different mechanisms, such as by the addition of crown ethers or replacing the solution-based electrolyte with polymer-based electrolytes. Typically, chelation using crown ethers has been used to suppress dendrite formation. − Abruña, Milner, and co-workers tested Li and K half-cells with 12-crown-4 and 18-crown-6 ethers, respectively, to introduce persistent chelating agents and probe ion–electrode interactions within PDI polymers (Figure ). While the addition of 18-crown-6 to K coin cells drastically decreased performance across all of the tested polymers, the results were mixed for cycling performances in Li coin cells with added 12-crown-4.…”

Electroactive materials are central to myriad applications, including energy storage, sensing, and catalysis. Compared to traditional inorganic electrode materials, redox-active organic materials such as porous organic polymers (POPs) and covalent organic frameworks (COFs) are emerging as promising alternatives due to their structural tunability, flexibility, sustainability, and compatibility with a range of electrolytes. Herein, we discuss the challenges and opportunities available for the use of redox-active organic materials in organoelectrochemistry, an emerging area in fine chemical synthesis. In particular, we highlight the utility of organic electrode materials in photoredox catalysis, electrochemical energy storage, and electrocatalysis and point to new directions needed to unlock their potential utility for organic synthesis. This Perspective aims to bring together the organic, electrochemistry, and polymer communities to design new heterogeneous electrocatalysts for the sustainable synthesis of complex molecules.
