“…One effective way is to increase the electronic conductivity by modifying the band gap of TiO 2 with the introduction of defects. Another way is to construct TiO 2 nanostructures such as nanosheets, nanowires, nanorods, nanotubes, and multi‐dimensional structures, [20,22,34,39] which not only increase specific surface areas, but also provide short diffusion lengths and improve the electronic conductivity.…”

Intercalation‐based anode materials can be considered as the most promising anode candidates for large‐scale sodium‐ion batteries (SIBs), owing to their long‐term cycling stability and environmental friendliness, as well as their natural abundance. Nevertheless, their low energy density, low initial coulombic efficiency, and poor cycling lifespan, as well as sluggish sodium diffusion dynamics are still the main issues for the application of intercalation‐based anode materials in SIBs in terms of meeting the benchmark requirements for commercialization. Over the past few years, tremendous efforts have been devoted to improving the performance of SIBs. In this Review, recent progress in the development of intercalation‐based anode materials, including TiO2, Li4Ti5O12, Na2Ti3O7, and NaTi2(PO4)3, is summarized in terms of their sodium storage performance, critical issues, sodiation/desodiation behavior, and effective strategies to enhance their electrochemical performance. Additionally, challenges and perspectives are provided to further understand these intercalation‐based anode materials.

“…Rechargeable sodium-ion batteries (SIBs) are very attractive in this regard, due to the abundance of inexpensive sodium resources [3,5,7,8]. Moreover, the similar electrochemistry and redox potentials of lithium and sodium (−3.02 and −2.71 V vs. SHE, respectively), make it a suitable candidate for efficient electrochemical energy storage [9][10][11]. However, the larger size of Na-ions compared to Li-ions (1.02 and 0.76 Å radius, respectively) hinders their intercalation in the most commonly used Li-ion battery anode material, graphite (interlayer d-spacing of 3.4 Å) [1,12,13].…”

“…polymorphs of TiO 2 have been investigated as promising Na-ion battery anodes [7,[27][28][29][30]. The existence of 2D intercalation channels in crystalline polymorphs make them superior to amorphous TiO 2 for Na-ion storage [4,9,31]. Hence, anatase TiO 2 composed of TiO 6 octahedra and zigzag edges of the 3-D network have become the most studied polymorph [4,32].…”

Although titanium dioxide has gained much attention as a sodium-ion battery anode material, obtaining high specific capacity and cycling stability remains a challenge. Herein, we report significantly improved surface chemistry and pseudocapacitive Na-ion storage performance of TiO2 nanosheet anode in vinylene carbonate (VC)-containing electrolyte solution. In addition to the excellent pseudocapacitance (~87%), the TiO2 anodes also exhibited increased high-specific capacity (219 mAh/g), rate performance (40 mAh/g @ 1 A/g), coulombic efficiency (~100%), and cycling stability (~90% after 750 cycles). Spectroscopic and microscopic studies confirmed polycarbonate based solid electrolyte interface (SEI) formation in VC-containing electrolyte solution. The superior electrochemical performance of the TiO2 nanosheet anode in VC-containing electrolyte solution is credited to the improved pseudocapacitive Na-ion diffusion through the polycarbonate based SEI (coefficients of 1.65 × 10−14 for PC-VC vs. 6.42 × 10−16 for PC). This study emphasizes the crucial role of the electrolyte solution and electrode–electrolyte interfaces in the improved pseudocapacitive Na-ion storage performance of TiO2 anodes.

“…materials are explored as high capacity anodes for Na-ion batteries, rapid capacity fading due to extreme volume changes and electrode pulverization make them unsuitable for SHCs applications. 10,102,[207][208][209][210] Cobalt oxides (CoO & Co3O4) are attractive for Na-ion storage owing to their high theoretical specific capacities (716 & 890 mAh• g -1 ). 142,199,211,212 However, these anodes experienced fast capacity fading due to large volume changes (~ 200%) and severe particle aggregation during the Na-ion insertion/extraction process.…”

“…Despite the excellent rate and cycling performance of these anodes, low specific capacity is inadequate for attaining desired energy density. 102,208,209 Conversion-type anodes based on transition metal oxide usually demonstrated negligible pseudocapacitance. Although extrinsic pseudocapacitance could be induced through nanoscale engineering, this technique remains indefinable mainly because of the sluggish Na-ion diffusion.…”
