“…The estimated energy consumption can be as low as 0.254 Wh L −1 for the desalination of brackish water (2500 ppm) to drinkable water (500 ppm). However, because currently few materials can be chosen as an efficient anion Faradaic electrode, the development of cost-efficient battery materials will also accelerate desalination technology [204][205][206][207].…”

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.

“…Recently, sodium superionic conductors (NASICONs), such as NaTi 2 (PO 4 ) 3 (NTP) (Huang et al, 2017(Huang et al, , 2019Guo et al, 2018;Wang et al, 2018;Zhang et al, 2020) and Na 3 V 2 (PO 4 ) 3 (NVP) (Cao J. L. et al, 2019;Cao X. X. et al, 2019), have been considered as promising cathode materials for sodium ion battery due to their high theoretical specific capacity and high Na + conductivity. Yang and co-workers fabricated a hybrid CDI cell with NaTi 2 (PO 4 ) 3 /rGO as positive electrode and activated carbon (AC) as negative electrode.…”

Clean energy and environmental protection are critical to the sustainable development of human society. The numerous emerged electrode materials for energy storage devices offer opportunities for the development of capacitive deionization (CDI), which is considered as a promising water treatment technology with advantages of low cost, high energy efficiency, and wide application. Conventional CDI based on porous carbon electrode has low salt removal capacity which limits its application in high salinity brine. Recently, the faradaic electrode materials inspired by the researches of sodium-batteries appear to be attractive candidates for next-generation CDI which capture ions by the intercalation or redox reactions in the bulk of electrode. In this mini review, we summarize the recent advances in the development of various faradaic materials as CDI electrodes with the discussion of possible strategies to address the problems present.

In order to meet the growing demands of electric vehicles and portable devices, the electrochemical performance of rechargeable batteries is required to be further optimized. Above all, it is of vital importance to understand the reaction mechanism of batteries under working states, which requires a direct observation of the complicated reaction process. Thus, in situ X‐ray diffraction (XRD) techniques have been employed in the charge and discharge process to realize real‐time monitoring and provide on‐site information of structural evolutions and phase transitions within electrode materials. In this review, a detailed summary of lab‐scale in situ X‐ray diffraction techniques is given and compared with in situ synchrotron XRD at the same time. First, four typical in situ reaction mechanisms are presented and their distinctive characteristics are introduced in detail. Second, the practical applications of in situ X‐ray diffraction in different battery systems are described with examples after extensive collections. In addition, the design of in situ cells and some noteworthy experimental details in actual testing are also mentioned. Finally, the further development direction of in situ X‐ray diffraction techniques is well prospected.
