Abstract: One dimensional Fe 7 S 8 @N−C nanocomposite, consisting of Fe 7 S 8 nanoparticles homogeneously embedded in N‐doped carbon nanowires, was synthesized by a facile hydrothermal‐annealing process. As an anode material for sodium‐ion batteries, the electrode exhibited capacities of 481 mA h g −1 after 1000 cycles at 5 A g −1 and 591 mA h g −1 at 200 mA g −1 with a retention ratio of 91 %. The excellent rate performance and cycling stability can be attributed to the synergistic effects of the one‐dimensional N‐doped carbon and ultra‐small Fe 7 S 8 particles, which will improve electrical conductivity and alleviate the volume expansion of the electrode during cycling. This work will afford a great reference for further development of iron sulfides‐based anode materials towards high‐performance sodium‐ion batteries.

Abstract: Limited by the development of energy storage technology, the utilization ratio of renewable energy is still at a low level. Lithium/sodium ion batteries (LIBs/SIBs) with high-performance electrochemical performances, such as large-scale energy storage, low costs and high security, are expected to improve the above situation. Currently, developing anode materials with better electrochemical performances is the main obstacle to the development of LIBs/SIBs. Recently, a variety of studies have focused on cobalt-based anode materials applied for LIBs/SIBs, owing to their high theoretical specific capacity. This review systematically summarizes the recent status of cobalt-based anode materials in LIBs/SIBs, including Li+/Na+ storage mechanisms, preparation methods, applications and strategies to improve the electrochemical performance of cobalt-based anode materials. Furthermore, the current challenges and prospects are also discussed in this review. Benefitting from these results, cobalt-based materials can be the next-generation anode for LIBs/SIBs.

Abstract: Sn‐based composites are considered as one of the promising anode materials for sodium‐ion batteries (SIBs) due to their high theoretical capacities and suitable operation voltages. However, they suffer the huge volume change and unstable electrolyte/electrode interface during sodiation/desodiation, which causes structure collapse and serious capacity loss. In the past few years, great efforts have been made to ameliorate the performances of Sn by rationally designing electrode structures/components or optimizing electrolyte composition. Here, the underlying sodium‐storage reactions in Sn are summarized based on the results from theoretical calculations and advanced characterizations. Then, the recent progresses of Sn‐based composites, i.e ., Sn‐based alloys, Sn/C composites, and Sn oxides/sulfides, with various structures for SIBs are discussed in details. After that, how the electrolyte affects solid‐electrolyte interphase and the electrochemical performances is shown. Finally, the future directions for the applications of Sn‐based composites in SIBs are suggested. Hence, this review provides a comprehensive scenario about the applications of Sn‐based composites in SIBs. It will benefit the future development of alloy‐type anodes in SIBs.

Abstract: Increasing the energy density of lithium-sulfur batteries necessitates the maximization of their areal capacity, calling for thick electrodes with high sulfur loading and content. However, traditional thick electrodes often lead to sluggish ion transfer kinetics as well as decreased electronic conductivity and mechanical stability, leading to their thickness-dependent electrochemical performance. Here, free-standing and low-tortuosity N, O co-doped wood-like carbon frameworks decorated with carbon nanotubes forest (WLC-CNTs) are synthesized and used as host for enabling scalable high-performance Li-sulfur batteries. EIS-symmetric cell examinations demonstrate that the ionic resistance and charge-transfer resistance per unit electro-active surface area of S@WLC-CNTs do not change with the variation of thickness, allowing the thickness-independent electrochemical performance of Li-S batteries. With a thickness of up to 1200 µm and sulfur loading of 52.4 mg cm −2 , the electrode displays a capacity of 692 mAh g −1 after 100 cycles at 0.1 C with a low E/S ratio of 6. Moreover, the WLC-CNTs framework can also be used as a host for lithium to suppress dendrite growth. With these specific lithiophilic and sulfiphilic features, Li-S full cells were assembled and exhibited long cycling stability.

Abstract: Sodium‐ion batteries show promising potential for large‐scale energy storage. However, the large size and heavy mass of Na + always results in huge volume change and inferior electrochemical stability, especially in alloy‐type anode materials. Here, molecular engineering of the polymer binders, i.e., cross‐linking of poly(acrylic acid) with glycerin (PAA‐GLY), reinforces the mechanical properties, eliminates the active protons of PAA, and benefits electrolyte diffusion, thereby remarkably improving electrochemical performance. Using µ‐Sn as an ex le, the cycle life at 2 A g −1 is extended from ≈26 cycles of PAA to ≈2000 cycles of PAA‐GLY. Meanwhile, the initial Coulombic efficiency is promoted to 90.3%, allowing the fabrication step of electrode presodiation for full cells to be eliminated. Thus, the full cells run 300 cycles at 2 A g −1 . In addition, the binder allows the thick electrode to exhibit an areal capacity of 6.8 mAh cm −2 . This binder is also applied for µ‐Bi and µ‐Sb. The simple operation, remarkable improvement, and wide applications indicate the promising prospects of this strategy for advanced electrodes in sodium ion batteries.

Abstract: Potassium ion batteries (PIBs), as a promising next‐generation electrochemical energy storage device, have drawn great attention in recent years due to the low price and abundant reserves of potassium resource. However, the severe electrode pulverization caused by repeatedly insertion/extraction of large radius of K + hinders their application. Herein a novel strategy is employed to fabricate hierarchical macroporous hybrid composite, ultrathin MoSe 2 nanosheets vertical growth on three‐dimension nitrogen‐doped cross‐linked macroporous carbon (HM‐MoSe 2 /N−C), via a template route and subsequent selenization process to alleviate the volume expansion and structure pulverization of the electrode. The electrochemical results demonstrate that the HM‐MoSe 2 /N−C is a good anode for PIBs including high specific capacity (222.8 mA h g −1 at 0.1 A g −1 ), superior rate capability, and long‐term cycling stability (172.5 mA h g −1 at 0.5 A g −1 after 400 cycles). The extraordinary electrochemical performance of this HM‐MoSe 2 /N−C electrode is attributed to the elegant and adequate nanostructure design, which can offer abundant exposed active sites (ultrathin MoSe 2 nanosheets), adequate volume accommodation (3D interconnected macropores), and highly conductive carbon frame with fast ion diffusion.

Abstract: Increasing the energy density and long‐term cycling stability of lithium‐ion batteries necessitates the stability of electrolytes under high/low voltage application and stable electrode/electrolyte interfacial contact. However, neither a single polymer nor liquid electrolyte can realize this due to their limited internal energy gap, which cannot avoid lithium‐metal deposition and electrolyte oxidation simultaneously. Herein, a novel type of quasi‐double‐layer composite polymer electrolytes (QDL‐CPEs) is proposed by using plasticizers with high oxidation stability (propylene carbonate) and high reduction stability (diethylene glycol dimethyl ether) in a poly(vinylidene fluoride) (PVDF)‐based electrolyte composites. In‐situ‐polymerized propylene carbonate can function as a cathode electrolyte interface (CEI) film, which can enhance the antioxidant ability. The nucleophilic substitution reaction between diethylene glycol dimethyl ether and PVDF increases the reduction stability of the electrolyte on the anodic side, without the formation of lithium dendrites. The QDL‐CPEs has high ionic conductivity, an enhanced electrochemical reaction window, adjustable electrode/electrolyte interphases, and no additional electrolyte–electrolyte interfacial resistance. Thus, this ingenious design of the QDL‐CPEs improves the cycling performance of a fabricated LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811)//QDL‐CPEs//hard carbon full cell at room temperature, paving a new way for designing solid‐state battery systems accessible for practical applications.
