“…Many of the alloy material elements (Sn, Sb, Ge, Se and P) can alloy with Na to form rich alloy phases [116,141] , such as Na 3.75 Sn (847 mAh/g) [142] , Na 3 Sb (660 mAh/g) [143] , Na 2 Se (678 mAh/g) [144] , and Na 3 P (2560 mAh/g) [35]. This is because they often deliver appropriate sodium inserting potential and high theoretical specific capacities [145][146][147][148][149].…”

“…To solve this problem, a great deal of endeavours have been attempted to develop composite alloys [150]. Thus, these intermetallics or alloy materials were often mixed with carbon [8,141,151,152]. For example, selenium (Se) combines with mesoporous carbon (Se 8 /mesoporous carbon) in a study reported by Wang et al [144].…”

“…The reduced 1st cycle irreversible capacity loss suggests less irreversible SEI formation. Notably, the increase of porosity in hard carbon is very powerfully associated with the lower reversible capacities, while the postmortem analysis indicates that the Sn@C surface morphology was broken after cycles and concluded that the large volumetric expansion can generate a huge radial and tangential stresses to easily break the carbon sheaths. Still, there is a challenge to control the Sn volume expansion.…”

In the scenario of renewable clean energy gradually replacing fossil energy, grid‐scale energy storage systems are urgently necessary, where Na‐ion batteries (SIBs) could supply crucial support, due to abundant Na raw materials and a similar electrochemical mechanism to Li‐ion batteries. The limited energy density is one of the major challenges hindering the commercialization of SIBs. Alloy‐type anodes with high theoretical capacities provide good opportunities to address this issue. However, these anodes suffer from the large volume expansion and inferior conductivity, which induce rapid capacity fading, poor rate properties, and safety issues. Carbon‐based alloy‐type composites (CAC) have been extensively applied in the effective construction of anodes that improved electrochemical performance, as the carbon component could alleviate the volume change and increase the conductivity. Here, state‐of‐the‐art CAC anode materials applied in SIBs are summarized, including their design principle, characterization, and electrochemical performance. The corresponding alloying mechanism along with its advantages and disadvantages is briefly presented. The crucial roles and working mechanism of the carbon matrix in CAC anodes are discussed in depth. Lastly, the existing challenges and the perspectives are proposed. Such an understanding critically paves the way for tailoring and designing suitable alloy‐type anodes toward practical applications.

“…During the first sodiation, along with formation of α‐NaSn phase, the large volume expansion increases the tensile residual stress; in turn, this residual stress affects α‐NaSn phase electronic structures with increasing resistivity of the Sn anode as shown in Figure c. Therefore, nanostructured design can mitigate stresses to improve the electrochemical performance . 3D Sn nanoforest anode arrays including a carbon outer shell, an Sn intermediate layer, and a metal inner core were fabricated and studied as anode materials for NIBs .…”

Sodium-ion batteries (NIBs), due to the advantages of low cost and relatively high safety, have attracted widespread attention all over the world, making them a promising candidate for large-scale energy storage systems. However, the inherent lower energy density to lithium-ion batteries is the issue that should be further investigated and optimized. Toward the grid-level energy storage applications, designing and discovering appropriate anode materials for NIBs are of great concern. Although many efforts on the improvements and innovations are achieved, several challenges still limit the current requirements of the large-scale application, including low energy/power densities, moderate cycle performance, and the low initial Coulombic efficiency. Advanced nanostructured strategies for anode materials can significantly improve ion or electron transport kinetic performance enhancing the electrochemical properties of battery systems. Herein, this Review intends to provide a comprehensive summary on the progress of nanostructured anode materials for NIBs, where representative examples and corresponding storage mechanisms are discussed. Meanwhile, the potential directions to obtain high-performance anode materials of NIBs are also proposed, which provide references for the further development of advanced anode materials for NIBs.
