The NaTi2(PO4)3 (NTP) anode materials exhibit high Na+ diffusion dynamics; carbon-based materials can effectively improve its limited electronic conductivity. However, the low Na+ diffusion of NTP/C composite materials from inhomogeneous carbon mixing or uncontrollable carbon coating cannot keep up with fast electron transfer, leading to undesirable electrochemical performances. Herein, a uniform and controllable carbon layer is designed on the self-supported-coated NTP nanorod arrays with binder-free (NTP@C NR) to improve Na+ and electron kinetics simultaneously. As a result, the NTP@C NR electrodes possess initial coulombic efficiency (ICE = 97%), good rate capabilities (89.1 mA h g–1 at 100 C), and stability with ≈78.4% of capacity retention rate at even 30 C over 1200 cycles. The sodium-ion capacitors with NTP@C NR as an anode and commercially activated carbon as a cathode exhibit ∼9180.0 W kg–1 of power density at 10 A g–1 and super high retention of ≈94.5% at 1 A g–1 over 7000 cycles. This work will help balance transport kinetics between the ion and electron for materials applied in storage devices.

“…Delmas et al first reported the reversible sodiation of NaTi 2 (PO 4 ) 3 in an organic electrolyte and revealed that two Na + ions could be reversibly intercalated to form Na 3 Ti 2 (PO 4 ) 3 via a two-phase mechanism [50] showing a pair of typical well-defined redox peaks at 2.2/2.0 V within the potential window of 1.6-2.6 V (vs. Na/Na + ) [44], and a number of research groups conducted a detailed structural elucidation of the electrochemical transition and structural control related to this compound [51][52][53][54][55][56]. To enhance the inherent low electronic conductivity of the phosphate framework especially for high-power SIBs application, numerous efforts have been made to improve its electrochemical performance by nanoarchitecturing the NTP particles and incorporating conductive carbon coating/networks (e.g., amorphous carbon, CNTs, or graphene) [45,48,[57][58][59][60][61][62][63].…”

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.

Though plenty of research has been conducted to improve the low intrinsic electronic conductivity of NASICON‐structured NaTi2(PO4)3 (NTP), realizing sodium‐ion batteries with high areal/volumetric capacity still remains a formidable challenge. Herein, a multiscale design from anode material to electrode structure is proposed to obtain a gadolinium‐ion‐doped and carbon‐coated NTP composite electrode (NTP‐Gd‐C), in which gadolinium ion doping, oxygen vacancy, optimized structure, N‐doped carbon coating, and bridging on the three‐dimensional network are simultaneously achieved. In the whole electrode, the excellent hierarchical electronic/ionic conductivity and structural stability are simultaneously improved via the synergistic optimization of NTP‐Gd‐C. As a result, excellent electrochemical performances of NTP‐Gd‐C electrode with a high areal/volumetric capacity of 1.0 mAh cm−2/142.8 mAh cm−3, high rate capability (58.3 mAh g−1 at 200 C), long cycle life (ultralow capacity fading of 0.004% per cycle under 10,000 cycles), and wide‐temperature electrochemical performances (97.0 mAh g−1 at 2 C under −20°C) are achieved. Moreover, the NTP‐Gd‐C//Na3V2(PO4)3/C full cell also delivers an excellent rate capacity of 42.0 mAh g−1 at 200 C and long‐term high‐capacity retention of 66.2% after 4000 cycles at 20 C.
