“…Third, it is necessary to construct full batteries from the current small size to large size, such as at Ah levels, to more accurately evaluate the prospects of lithiated organic cathode materials for practical LIBs. Finally, recent works have extended the lithiated organic battery chemistries to the sodiated and potassiated counterparts, where the sodium‐ion and potassium‐ion half or full batteries also show good electrochemical performance [37, 54, 55] . Thus, the sodiated and potassiated organic cathode materials may also be competitive in these fields and worth investigation in the future.…”

“…In contrast, the lithiated compounds with high redox potentials above 3 V (vs. Li + /Li), like Li 4 ‐ p ‐DOBDA, [30] tetralithium 2,5‐dihydroxy‐1,4‐benzenedisulfonate (Li 4 ‐ p ‐DHBDS), [32] Li 2 ‐Mg‐ p ‐DHT, [29] and Li‐TCNQ, [33] are stable with O 2 in air. It should be noted that although the average potential of Li 2 ‐Co‐PTtSA in Figure 3 is higher than 3 V (from Li 2 ‐Co‐PTtSA to Co‐PTtSA), it still shows a little oxidation in air, which may result from the low potential of the conversion from Li 2 ‐Co‐PTtSA to Li‐Co‐PTtSA (<2.9 V vs. Li + /Li) [37] . Detailed strategies to tune the potential and thus the air stability of lithiated organic cathode materials will be discussed in the next section.…”

Organic electrode materials have application potential in lithium batteries owing to their high capacity, abundant resources, and structural designability. However, most reported organic cathodes are at oxidized states (namely unlithiated compounds) and thus need to couple with Li-rich anodes. In contrast, lithiated organic cathode materials could act as a Li reservoir and match with Li-free anodes such as graphite, showing great promise for practical full-battery applications. Here we summarize the synthesis, stability, and battery applications of lithiated organic cathode materials, including synthetic methods, stability against O 2 and H 2 O in air, and strategies to improve comprehensive electrochemical performance. Future research should be focused on new redox chemistries and the construction of full batteries with lithiated organic cathodes and commercial anodes under practical conditions. This Minireview will encourage more efforts on lithiated organic cathode materials and finally promote their commercialization.

Potassium‐ion batteries (PIBs) are gradually gaining attention owing to their natural abundance, excellent security, and high energy density. However, developing excellent organic cathode materials for PIBs to overcome the poor cycling stability and slow kinetics caused by the large radii of K+ ions is challenging. This study demonstrates for the first time the application of a hexaazanonaphthalene (HATN)‐based two‐dimensional π‐d conjugated metal‐organic framework (2D c‐MOF) with dual‐active centers (Cu‐HATNH) and integrates Cu‐HATNH with carbon nanotubes (Cu‐HATNH@CNT) as the cathode material for PIBs. Owing to this systematic module integration and more exposed active sites with high utilization, Cu‐HATNH@CNT exhibited a high initial capacity (317.5 mA h g−1 at 0.1 A g−1), excellent long‐term cycling stability (capacity retention of 96.8% at 5 A g−1 after 2200 cycles), and outstanding rate capacity (147.1 mA h g−1 at 10 A g−1). The reaction mechanism and performance were determined by combining experimental characterization and density functional theory (DFT) calculations. This contribution provides new opportunities for designing high‐performance 2D c‐MOF cathodes with multiple active sites for PIBs.This article is protected by copyright. All rights reserved

Versatile nitrogen‐centered organic redox‐active molecules have gained significant attention in alkali metal‐ion batteries (AMIBs) due to their low cost, low toxicity, and ease of preparation. Specially, their multiple reaction categories (anion/cation insertion types of reaction) and higher operating voltage, when compared to traditional conjugated carbonyl materials, underscore their promising prospects. However, the high solubility of nitrogen‐centered redox active materials in organic electrolyte and their low electronic conductivity contribute to inferior cycling performance, sluggish reaction kinetics, and limited rate capability. This review provides a detailed overview of nitrogen‐centered redox‐active materials, encompassing their redox chemistry, solutions to overcome shortcomings, characterization of charge storage mechanisms, and recent progress. Additionally, we propose prospects and directions for future investigations. It is anticipated that this review will stimulate further exploration of underlying mechanisms and interface chemistry through in situ characterization techniques, thereby promoting the practical application of nitrogen‐centered redox‐active materials in AMIBs.This article is protected by copyright.
