“…Lithium-ion batteries (LIBs) are widely utilized in the portable electronics owing to their numerous merits, such as high energy density, long lifespan, and environmental friendliness [1][2][3][4]. Nevertheless, to meet the ever-growing demand for longer distance electric vehicles and more advanced electrical devices, the energy density of commercially available LIBs needs to be further enhanced [5][6][7].…”

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.

Red phosphorus has been regarded as an attractive candidate for the anode of sodium‐ion batteries (NIBs) because it delivers a high theoretical capacity (2596 mAh g−1) at low potentials. However, the electrochemical performances of red P are still not satisfactory for viable applications mainly due to its intrinsic low conductivity and large volume swelling associated with sodiation reactions. Here, we develop onion‐like mesoporous carbon nanoparticles (OCNPs) to serve as conductive host for red P. The OCNPs can alleviate the large volume swelling of red P, and allow the fast electron and Na+ transport. The resulting P/OCNPs composite electrode achieves excellent rate performance of 1286.7 mAh g−1 at 2 C, and retained discharge capacity of 1057.5 mAh g−1 after 150 cycles at 0.5 C. The improved stability of the composite electrode is also confirmed by the structure integrity after the cycling test. Our work presents a feasible approach to address the challenges of red P for high‐capacity anode of NIBs.
