Summary: NASICON structure type materials are gaining attention as electrode active materials for ion insertion batteries and deionization devices. NaTi2(PO4)3 is a suitable negative electrode due to its favorable potential in aqueous electrolytes. However, parasitic processes limit its efficiency and capacity retention, making it important to understand and mitigate these processes.

Summary: This study presents a comprehensive investigation on the size- and shape-controlled hydro(solvo)thermal synthesis of NaTi2(PO4)3 nanoparticles. The effects of different alcohol/water synthesis media on phase purity, morphology, and size distribution of the nanoparticles are analyzed. It is found that the water activity in the synthesis media of different alcohol solutions is the key parameter governing the phase purity, size, and shape of the nanoparticles. The careful engineering of NaTi2(PO4)3 nanoparticle morphology allows control of the electrochemical performance and degradation of these materials as aqueous Na-ion battery electrodes.

Summary: Due to low intrinsic electronic conductivity, NASICON-structured materials such as NaTi2(PO4)(3) must be composited with carbon to form suitable electrodes for power applications. In this study, two types of NaTi2(PO4)(3)-carbon composite structures were successfully prepared using different approaches. The results show that the carbon loading control and particle coatings were more uniform and continuous in the samples prepared through surface polymerized dopamine. Careful nanostructure engineering could yield materials with superior properties and stability suitable for various electrochemical applications.

Summary: Researchers attempted to modify the surface of NaTi2(PO4)(3) (NTP), an electrode material for aqueous Na-ion batteries (ASIBs), by using a material with Na-ion conductivity. NTP prepared with excess Na2CO3 showed improved cyclability and rate capability, even in a low salt concentration aqueous electrolyte. Analysis revealed that the NTP particle surface was modified by a Na-rich phase such as Na3Ti23+(PO4)(3). Additionally, the prepared NTPs had high crystallinity, which contributed to their good rate capability.

Summary: The synthesized hollow-structure NTP encapsulated in cross-linked porous N-doped carbon nanofiber (HNTP@PNC) directly acts as a binder-free anode for flexible ARSIBs, showing high rate capacity and cycling stability. The NTP with NC coating enhances electronic conductivity and Na+ diffusion kinetics, leading to the success in constructing a high-performance quasi-solid-state ARSIB with a high energy density and volumetric capacity.

Summary: This study proposes a carbon-coated porous NTP olive-like nanospheres (p-NTP@C) as an anode material for sodium-ion batteries (SIBs), to address the issues of low electronic conductivity and charge transfer kinetics limitations. The porous structure provides more active sites and shorter Na diffusion distance, while the carbon coating improves electron and Na diffusion kinetics. The p-NTP@C nanospheres exhibit high reversible capacity and ultrastable cycling performance, making them a viable option for long-life and highly stable NASICON-type anode materials.
