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.

“…[13][14][15][16][17][18][19] A wide range of T-Nb 2 O 5 nanoscale architectures [20,21] have been investigated to date with most demonstrations including remarkable charge/ discharge rates.

“…[23,[52][53][54] These studies relied on either the simultaneous variation of multiple spatial parameters or were based on single parameter architectures, thus obfuscating the study of nanostructure-property relationships. Prior works on T-Nb 2 O 5 have also included theoretical studies, [55] comparisons of different crystallographic phases, [36,53,56] and correlated the high diffusion coefficient of Li in T-Nb 2 O 5 with its crystallographic features. [8,57,58] In contrast to recent reports of rapid lithium intercalation into nanostructured T-Nb 2 O 5 , the first investigation of this system by Bard et al in 1981 without deliberate nanoscale porosity resulted in a sluggish electrochemical response, requiring 24 h for lithium intercalation to complete.…”

Intercalation pseudocapacitance has emerged as a promising energy storage mechanism that combines the energy density of intercalation materials with the power density of capacitors. Niobium pentoxide was the first material described as exhibiting intercalation pseudocapacitance. The electrochemical kinetics for charging/discharging this material are surface‐limited for a wide range of conditions despite intercalation via diffusion. Investigations of niobium pentoxide nanostructures are diverse and numerous; however, none have yet compared performance while adjusting a single architectural parameter at a time. Such a comparative approach reduces the reliance on models and the associated assumptions when seeking nanostructure–property relationships. Here, a tailored isomorphic series of niobium pentoxide nanostructures with constant pore size and precision tailored wall thickness is examined. The sweep rate at which niobium pentoxide transitions from being surface‐limited to being diffusion‐limited is shown to depend sensitively upon the nanoscale dimensions of the niobium pentoxide architecture. Subsequent experiments probing the independent effects of electrolyte concentration and film thickness unambiguously identify solid‐state lithium diffusion as the dominant diffusion constraint even in samples with just 48.5–67.0 nm thick walls. The resulting architectural dependencies from this type of investigation are critical to enable energy‐dense nanostructures that are tailored to deliver a specific power density.

“…However, LIBs using organic liquid electrolyte also have some unfavorable features including the leakage, highly volatile ability, and flammability of organic liquid electrolyte system and the growth of lithium dendrites, which may cause the degeneration of battery performance or even some unpredictable dangerous safety accidents . On the other hand, the rapid development of technology makes people desire higher energy density energy storage equipment, which may use the new kind of cathode material, Li‐rich, Ni‐rich, and Lithium‐sulfur, and anode material, SiC, graphite material. Although using the above‐mentioned materials can markedly increase the energy density of LIBS, the battery safety and energy density are still a matter of general interest until the new systems using all solid‐state electrolyte (ASSE) are introduced .…”

Poly(ethylene oxide) (PEO) is one of the most promising candidates in polymer solid‐state electrolyte. However, the polymer matrix has a high degree of crystallinity and thus manifests low conductivity, which restricts its application in all solid‐state lithium‐ion battery. Herein, a new composite polymer electrolyte (PLWLS), which is comprised of PEO, LiClO4, and the independently synthetized walnut‐like SiO2 (WLS) as nano‐fillers, is designed and prepared by the tape‐casting way. The optimum mass fraction of walnut‐like SiO2 is determined by physical and electrochemical characterization. The result shows that the PLWLS‐15 with 15 wt % walnut‐like SiO2 nanoparticles has a crystallinity of 13.7%. Similarly, the maximum tensile strength is improved greatly. The assembled all‐solid‐state lithium‐ion battery with LiFePO4/PLWLS‐15/Li exhibits a higher discharge capacity of 167 mAh g−1 at 0.1 C (1C = 170 mAh g−1) and 143 mAh g−1 at 0.5 C in first cycle, lower voltage polarization and better cycle performance. Therefore, adding nanoparticle into PEO‐based solid‐state electrolyte could effectively promote the mechanical property and electrochemical performance, and thus provide a possibility of application for PLWLS‐15 in next generation all solid‐state lithium battery. © 2019 Wiley Periodicals, Inc.
