Transition-metal sulfides (TMSs) powered by conversion and/or alloying reactions are considered to be promising anode materials for advanced lithium-ion batteries (LIBs) and sodium-ion (SIBs). However, the limited electronic conductivity large volume expansion severely hinder their practical application. Herein, we report a covalent coupling strategy TMS-based using amide linkages bind TMSs carbon nanotubes (CNTs). In synthesis, thiourea acts as not only capping agent morphology control but also linking coupling. As proof of concept, covalently coupled ZnS/CNT composite (CC-ZnS/CNT) has been prepared, with ZnS nanoparticles (∼10 nm) tightly anchored on CNT bundles. The compact ZnS-CNT heterojunctions greatly beneficial facilitating electron/ion transfer ensuring structural stability. Due strong interaction between CNTs, presents prominent pseudocapacitive behavior highly reversible electrochemical processes, thus leading superior long-term stability excellent rate capability, delivering capacities 333 mAh g–1 at 2 A over 4000 cycles LIBs 314 5 after 500 SIBs. Consequently, CC-ZnS/CNT exhibits great competence applications in SIBs, is proposed approach designing high-performance materials.

Lithium-sulfur (Li-S) batteries have great potential as high-energy-density energy storage devices. Electrocatalysts are widely adopted to accelerate the cathodic sulfur redox kinetics. The interactions among electrocatalysts, solvents, and lithium salts significantly determine actual performance of working Li-S batteries. Herein, bis(trifluoromethanesulfonyl)imide (LiTFSI), a commonly used salt, is identified aggravate surface gelation on MoS2 electrocatalyst. In detail, trifluoromethanesulfonyl group in LiTFSI interacts with Lewis acidic sites electrocatalyst generate an electron-deficient center. center high acidity triggers cationic polymerization 1,3-dioxolane solvent generates gel layer that reduces electrocatalytic activity. To address above issue, basic salt iodide (LiI) introduced block interaction between inhibit gelation. Consequently, LiI additive realize ultrahigh density 416 W h kg-1 at pouch cell level. This work affords effective boost activity practical deepens fundamental understanding systems.

Rechargeable aqueous zinc ion batteries (AZIBs) promise high energy density, low redox potential, cost and safety; however, their cycle performances are seriously insufficient to restrict the progress in this field. We propose a new concept of atomic electrode formed on graphdiyne (GDY). This idea was synthesized by selectively, uniformly, stably anchoring Zn atoms GDY at beginning plating. The induced grow into larger size clusters, which continue nanoflat. Finally, heterojunction interface is without any dendrites side reactions, even current densities. Such stepwise induction growth greatly suppresses formation dendrites, resulting electroplating/stripping reversibility lifespan AZIBs.

Abstract Hybrid capacitors exhibit promise to bridge the gap between rechargeable high‐energy density batteries and high‐power supercapacitors. This separation is due sluggish ion/electron diffusion inferior structural stability of battery‐type materials. Here, a topochemistry‐driven method for constructing expanded 2D rhenium selenide intercalated by nitrogen‐doped carbon hybrid (E‐ReSe 2 @INC) with strong‐coupled interface weak van der Waals forces, proposed. X‐ray absorption spectroscopy analysis dynamically tracks transformation from ReO into ReC bonds. The bridging bonds act as electron transport channels enable improved conductivity accelerated reaction kinetics. interlayer‐spacing ReSe layer INC facilitates ion ensures stability. As expected, E‐ReSe @INC achieves an rate capability (252.5 mAh g −1 at 20 A ) long‐term cyclability (89.6% over 3500 cycles). Moreover, theoretical simulations reveal favorable Na + storage kinetics can be ascribed its low bonding energy −0.06 eV barrier 0.08 sodium ions. Additionally, it demonstrated that 3D printed sodium‐ion deliver high energies/power densities 81.4 Wh kg /0.32 mWh cm −2 9992.1 W /38.76 mW , well applicability in wide temperature range.
