“…The obvious lattice distortion and mismatch at the interface would create a large amount of crystal defects and accessible active sites for Na + ions, which is beneficial for ion insertion and extraction in cycling processes. [14] The selected-area electron diffraction (SAED) image (Figure 1g) also confirms the co-existence of ZnSe and SnSe 2 . C, N, O, Zn, Sn, and Se elements are homogeneously distributed inside the material, as is shown in Figure 1h.…”

Rationally designed electrode materials with high capacity, long cycle life, and low cost are indispensable for sodium‐ion batteries. Herein, a hierarchical nanobox consisting of a heterojunction bimetallic selenide yolk and polydopamine shell (denoted as SnSe2/ZnSe@PDA) is engineered and fabricated successfully. Owing to the charge redistribution and lattice distortion at the hetero‐phase boundaries, Na+ ions can be easily adsorbed and transferred swiftly, facilitating the reaction kinetics and promoting cycling behavior. By means of the hollow structure and elastic polymer shell, this approach can synergistically alleviate volume fluctuation and the aggregation of active nanomaterials during cycling. This material delivers a high reversible capacity of 616 mA h g‐1 at 1 A g‐1 over 1000 long‐term cycles, and superior rate capability, which provides more possibilities for the practical applications of energy storage in the future.

“…They are accessible and active sites for the Na + storage, namely beneficial for Na + insertion and extraction during the cycling processes. [28] Furthermore, in the XRD curves of the fully discharged and charged CZTS@C anode after 50 charge/ discharge cycles (Figure S15, Supporting Information), a weak signal of the (422) plane of NaZn 13 is found, suggesting the occurrence of an alloying reaction. The obvious diffraction peaks of the charged products in the 50th cycle correspond to the (112) plane of CZTS and the (200) plane of Cu 2 SnS 3 , respectively.…”

Recent years have witnessed the flourish of lithium-ion batteries (LIBs) in the energy storage markets, ranging from smart vehicles to portable electronic devices. This is because LIBs feature a long cycling lifetime and prominent energy densities. Nevertheless, the limited lithium sources on the earth impose restrictions on the application of LIBs in our daily life. [1] As a next-generation alternative energy storage system to LIBs, sodium-ion batteries (SIBs) have received considerable attention, owing to the natural abundance of Na sources and more importantly their similar energy storage mechanisms to LIBs. [2] However, the ionic radius of a Na + ion (1.02 Å) is larger than that of a Li + ion (0.76 Å), resulting in the huge volume expansion and sluggish electrochemical reaction kinetics during the SIB charge/discharge process. [3] To develop and configure highperformance SIBs, the design of highly stable SIB anode materials is thus of great significance.Recently, various 2D materials (e.g., MXenes, MXene composites, [4] metal-organic frameworks and their derivatives) [5] and 3D ones (e.g., carbon materials) [6] have been explored as the SIB anode candidates. Besides them, transition metal sulfides (TMSs) have been frequently applied, owing to their chemical/ structural stability, low cost, and eco-friendliness. [7] The open architectures of TMSs also provide the facilitations in ionic mobility for the insertion/desertion and diffusion of Na + ions. Such a reaction mechanism in the TMSs has been revealed as a multistep process, including conversion and alloying/dealloying reactions. These reactions guarantee the outstanding theoretical capacities and relatively considerable redox reversibility that is benefited from the weak MS bonds. During the long-term cycling, the conversion reaction in TMSs (MS 2 + 4Na + → M + 2Na 2 S) inevitably leads to severe volume expansion of the TMS anodes. Their drastic construction collapses and thus sharp decays of the capacities occur. It is also known that the alloying-dealloying process at a lower redox potential followed by the conversion reaction always depends upon the alloy formation ability of sodium and metal. [8] However, owing to the poor electrical conductivity, drastic volume changes, and sluggish sodium diffusion kinetics, the limited cycling lifespan and inferior cycling performance of TMSs, these SIBs are still far from what is expected for their scale-up production.The sodium-ion battery (SIB) is one of the new generation of electrochemical energy storage devices, although its life-time needs to be improved. To assemble an SIB with an ultralong life-time, passionfruit-like Cu 2 ZnSnS 4 nanoparticles confined with nitrogen-doped carbon (CZTS@C) are synthesized. As an alternative anode for an SIB, the CZTS@C anode exhibits a reversible capacity of 461 mA h g −1 at a current density of 50 mA g −1 after 140 charge/ discharge cycles and excellent cycling stability (e.g., a capacity of 146 mA h g −1 at 4 A g −1 even after 1000 charge/discharge cycles). Such high pe...

Summary Lithium‐ion batteries(LIBs) have been widely used in people's daily lives. At the same time, in the face of the growing demand for LIBs, the minable lithium mines on the earth are facing resource exhaustion. From the perspective of sustainable development, it is inevitable to seek new batteries. Sodium‐ion batteries(SIBs) are attracting attention due to their rich resources and low cost, and are expected to be used in large‐scale energy storage. In recent years, anode materials have made a lot of important progress as the key elements of SIBs. The research of anode materials is mainly concentrated on carbon‐based materials, titanium‐based materials, alloying materials, conversion materials, and organic materials. However, due to the large sodium ion radius, the large volume change of materials, and slow kinetics, the electrochemical performance of the materials is poor. This article systematically summarizes the latest research progress of these types of anode materials and discusses the main existing problems and the solution strategy and the prospect of the development of negative electrode materials.
