large size of sodium-ions, there are also uniqueness in the development of SIB materials and the tuning of electrodeelectrolyte interphases, etc. [3] One of the most representative examples is that the intercalation of sodium-ion in graphite is thermodynamically inhibited by the interlayer distance, whereas the lithium-ion intercalation is favorable. [1,3] Hard carbon (HC) with expanded interlayer distance was investigated as the-state-of-the-art anode that allows sodium-ion storage via pore absorption, defect binding, and intercalation into the turbostratic graphenic nanodomains. [4][5][6][7] HC structure and the unique ion storage mechanism inevitably induce more reduction decomposition of the electrolyte, solid electrolyte interphase (SEI) formation, ion trapping, and hence lead to worse Coulombic efficiency than graphite. [8] Delicate control of the HC defects and surface area is therefore particularly required. [5,9] It is known that the electrochemical reversibility and the rate and life performance of LIBs and SIBs are to a great extent dictated by the SEI formation and its chemical/electrochemical reactivity and stability. [5,10,11] Concerning this, attempts also have been made to tune the SEI coverage, thickness, stability, and ionic conductivity, etc., by developing novel electrolytes or electrolyte additives that decompose preferentially to form SEI or tailoring the surface area and physiochemical properties of the carbon materials. [10][11][12][13] Ether-based electrolyte has been extensively used in lithium-air and lithiumsulfur batteries. [14,15] The solvent-in-salt electrolyte design also has expanded the application of ether electrolyte to LIBs with graphite anodes and high-voltage cathodes. [16,17] In SIBs, ether Hard carbon (HC) is the state-of-the-art anode material for sodium-ion batteries (SIBs). However, its performance has been plagued by the limited initialCoulombic efficiency (ICE) and mediocre rate performance. Here, experimental and theoretical studies are combined to demonstrate the application of lithium-pretreated HC (LPHC) as high-performance anode materials for SIBs by manipulating the solid electrolyte interphase in tetraglyme (TEGDME)-based electrolyte. The LPHC in TEGDME can 1) deliver > 92% ICE and ≈220 mAh g −1 specific capacity, twice of the capacity (≈100 mAh g −1 ) in carbonate electrolyte; 2) achieve > 85% capacity retention over 1000 cycles at 1000 mA g −1 current density (4 C rate, 1 C = 250 mA g −1 ) with a specific capacity of ≈150 mAh g −1 , ≈15 times of the capacity (10 mAh g −1 ) in carbonate. The full cell of Na 3 V 2 (PO 4 ) 3 -LPHC in TEGDME demonstrated close to theoretical specific capacity of ≈98 mAh g −1 based on Na 3 V 2 (PO 4 ) 3 cathode, ≈2.5 times of the value (≈40 mAh g −1 ) with nontreated HC. This work provides new perception on the anode development for SIBs.

Sodium‐ion batteries (SIBs) have been considered as the most promising candidate for large‐scale energy storage system owing to the economic efficiency resulting from abundant sodium resources, superior safety, and similar chemical properties to the commercial lithium‐ion battery. Despite the long period of academic research, how to realize sodium‐ion battery commercialization for market applications is still a great challenge. Thus, from the perspective of future practical application, this review will identify the factors that are restricting commercialization, and evaluate the existing active materials and sodium‐ion‐based full‐cell system. The design and development trends that are needed for SIBs to meet the requirements of practical applications in large‐scale energy storage will also be discussed in detail.

“…Recently, Na-ion batteries (NIBs) have attracted widespread attention as a potential alternative to LIBs due to their earth abundance, low cost and low redox potential [6,7]. There is an increasing demand for LIBs with higher energy density, which facilitates the study of various LIB electrode materials [8][9][10]. The same impetus also drives current NIB research [11][12][13].…”

To enhance electrochemical performance of lithium or sodium-ion batteries (LIBs or NIBs), active materials are usually filled in porous conductive particles to produce anode composites. However, it is still challenging to achieve high performance anode composites with high specific capacity, excellent rate performance, high initial Coulombic efficiency (ICE) and long cycle life. Based on these requirements, we design and fabricate activated carbon-coated carbon nanotubes (AC@CNT) with hierarchical structures containing micro-and meso-pores. A new structure of phosphorus/carbon composite (P@AC@CNT) is prepared by confining red P in porous carbon through a vaporization-condensation-conversion method. The micro-pores are filled with P, while the meso-pores remain unoccupied, and the pore openings on the particle surface are sealed by P. Due to the unique structure of P@AC@CNT, it displays a high specific capacity of 1674 mA h g −1 at 0.2 C, ultrahigh ICE of 92.2%, excellent rate performance of 1116 mA h g −1 at 6 C, and significantly enhanced cycle stability for LIBs. The application of P@AC@CNT in NIBs is further explored. This method for the fabrication of the special composites with improved electrochemical performance can be extended to other energy storage applications.
