“…Such a 3D porous structure promotes the contact between the electrolyte and electrode, while the abundance of micropores help expedite the transport of electrons and ions. [ 36 ] The digital photograph in Figure 6d shows the 3DP full cell can readily power LEDs. Figure S29 (Supporting Information) shows the successful printing of 1, 3 and 5 layers of the grid electrode, indicative of the great control over the mass loading of the active materials by the 3DP technique.…”

Sodium‐ion batteries (SIB), as one of the most appealing grid‐scale energy storage devices, have to deal with the trade‐off between the capacity output and rate performance. Utilizing 3D‐printed (3DP) anode materials with hybrid sodium storage mechanism and elevated mass loading is promising yet poorly explored. Herein, the design of a prototype ternary composite is reported, MoS2@Bi/N‐doped carbon, as a sodium storage candidate to achieve high reversible capacity (604 mAh g−1 at 0.1 A g−1 with an initial output of 709 mAh g−1) and outstanding rate capability (169.6 mAh g−1 at 15 A g−1), outperforming the state‐of‐the‐art reports. This is realized by delicate structural and interfacial engineering of the composite anode, markedly synergizing the conversion‐typed MoS2, alloy‐typed Bi, and adsorption‐typed N‐doped carbon. Theoretical simulations and operando instrumental analysis elaborate the reasons of the boosted electrochemical performance. Encouragingly, a fully 3DP SIB affording an areal mass loading of up to 11.7 mg cm−2 is demonstrated, retaining a capacity of 114 mAh g−1 at 1.0 A g−1. This work would facilitate the design of 3DP SIB devices with the employment of advanced electrodes harnessing hybrid ion storage features.

“…However, due to the low conductivity of the converted anode materials and the large volume change in the process of intercalation/deintercalation, their practical application has been hindered. Therefore, effective strategies to solve these problems have been explored through carbon recombination [53], core-shell structures [54], defect engineering [55], etc.…”

Transition metal selenides have narrow or zero band-gap characteristics and high theoretical specific capacity. Among them, cobalt selenide and cobalt telluride have some typical problems such as large volume changes, low conductivity, and poor structural stability, but they have become a research hotspot in the field of energy storage and conversion because of their high capacity and high designability. Some of the innovative synthesis, doping, and nanostructure design strategies for CoSex and CoTex, such as CoSe-InCo-InSe bimetallic bi-heterogeneous interfaces, CoTe anchoring MXenes, etc., show great promise. In this paper, the research progress on the multistep transformation mechanisms of CoSex and CoTex is summarized, along with advanced structural design and modification methods such as defect engineering and compositing with MXenes. It is hoped that this review will provide a glimpse into the development of CoSex and CoTex anodes for alkali-ion batteries.

“…In recent years, the carbon peaking and carbon neutrality goals have promoted the optimization of the energy structure, and new energy including solar energy, wind energy, and various electrochemical energy has gradually become the mainstream energy. − As one of the important electrochemical energy storage devices, lithium-ion batteries (LIBs) have been extensively applied in portable electronics, electric vehicles (EVs), and hybrid EVs. − However, the increasingly prominent problem of lithium and cobalt resources seriously impedes future applications in large-scale storage fields. As one of the most prospected alternatives, Na + -ion batteries (SIBs) with the merits of low cost, high safety, and a similar mechanism to that of LIBs have attracted significant interest, exhibiting great potential in the large-scale application of renewable energy storage. − Nevertheless, the large radius of Na + always leads to the sluggish diffusion kinetics and large volume change of anodes during continuous discharging/charging, leading to poor cycle performance and inferior rate performance.…”

MoSe 2 has attracted significant interest for Na + storage due to its large interlayer distance, favorable band gap structure, and satisfying theoretical specific capacity. Nevertheless, the poor conductivity and large volume stress/strain always lead to poor cycle stability and limited rate capability. Herein, the P−Se bond and phase engineering strategies are proposed to enhance the stability of MoSe 2 with the assistance of carbon compositing. Systematical characterizations confirm that the presence of a strong P−Se bond can ensure the good structural stability and enlarge the layer distance of the MoSe 2 anode. 1T phase-enriched composition endows excellent conductivity and thus fast Na + transport kinetics. Additionally, the combination of carbon contributes to the improvement of electron conductivity, further enhancing the reversible Na + storage and cyclic stability. Consequently, an ultrastable reversible specific capacity of 347.8 mAh g −1 with a high retention ratio of 99.1% can be maintained after 1000 cycles at 1 A g −1 , which is superior to the previous reports of MoSe 2 nanosheets. The presented strategy is ingenious, offering an effective guidance to designing advanced electrodes to be applied in rechargeable batteries with a long lifespan.
