“…The high-resolution SEM image (Figure 2B) shows that the carbon nanosheets are curved and have an average thickness of ~10 nm. SEM images of NaTi 2 (PO 4 ) 3 (Figures 2C,D) show that the products have uniform cubic shapes and their sizes are in the range between 50 and 100 nm, similar with the results reported in literatures (Liang et al, 2018a). …”

“…For example, the coating of carbon or graphene on NaTi 2 (PO 4 ) 3 micro/nanostructures can effectively improve their properties and higher quality of the conductive materials could result in better electrochemical performance. Nevertheless, the contents of carbon or graphene in the previously reported composites were only 3.4–6.8 wt% (Pang et al, 2014b; Fang et al, 2016; Geng et al, 2017; Hu Q. et al, 2018; Liang et al, 2018a). Thus, to obtain better electrochemical properties, the contents of conduction materials should be increased.…”

NaTi2(PO4)3 has attracted great interest as anode material for sodium ion batteries owing to its open three-dimensional framework structure and limited volume changes during the charge and discharge process. However, the poor intrinsic electronic conductivity of NaTi2(PO4)3 needs to be improved for high rate capability. In this work, porous NaTi2(PO4)3 nanocubes anchored on porous carbon nanosheets (NaTi2(PO4)3/C) are designed and developed. This material exhibits a large discharge capacity and good rate capacity including a first discharge capacity of 485 mAh g−1 at a current density of 0.1 A g−1, and 98 mAh g−1 retained at a high rate of 4 A g−1 even after 2,000 cycles. These results suggest that NaTi2(PO4)3/C is a promising anode material for sodium-ion batteries.

“…S4b †), which corresponded to the Ti(IV)/Ti(III) and V(IV)/V(III) redox couples, respectively. 44,45 The overpotentials of the NTP/CNFs anode and NVP/CNFs cathode were 0.24 V and 0.13 V, respectively, which were slightly higher than those in previous reports 18,46 owing to the inuence of the high scan rate. In addition, a shoulder appeared at 3.53 V during the oxidation process owing to side reactions on the CNT surface in the NVP/CNFs electrode, as in the previous case of the CNFs half cell.…”

HIGHLIGHTS • For the first time, we fully presented the recent progress of the application of NaTi 2 (PO 4) 3 on sodium-ion batteries including nonaqueous batteries, aqueous batteries, aqueous batteries with desalination, and sodium-ion hybrid capacitors. • The unique NASICON structure of NaTi 2 (PO 4) 3 and the various strategies on improving the performance of NaTi 2 (PO 4) 3 electrode have been presented and summarized in detail. ABSTRACT Several emerging energy storage technologies and systems have been demonstrated that feature low cost, high rate capability, and durability for potential use in large-scale grid and high-power applications. Owing to its outstanding ion conductivity, ultrafast Na-ion insertion kinetics, excellent structural stability, and large theoretical capacity, the sodium superionic conductor (NASICON)-structured insertion material NaTi 2 (PO 4) 3 (NTP) has attracted considerable attention as the optimal electrode material for sodium-ion batteries (SIBs) and Na-ion hybrid capacitors (NHCs). On the basis of recent studies, NaTi 2 (PO 4) 3 has raised the rate capabilities, cycling stability, and mass loading of rechargeable SIBs and NHCs to commercially acceptable levels. In this comprehensive review, starting with the structures and electrochemical properties of NTP, we present recent progress in the application of NTP to SIBs, including non-aqueous batteries, aqueous batteries, aqueous batteries with desalination, and sodium-ion hybrid capacitors. After a thorough discussion of the unique NASICON structure of NTP, various strategies for improving the performance of NTP electrode have been presented and summarized in detail. Further, the major challenges and perspectives regarding the prospects for the use of NTP-based electrodes in energy storage systems have also been summarized to offer a guideline for further improving the performance of NTP-based electrodes.
