“…Let us address the more electro‐active NASICON compounds such as Fe 2 (MoO 4 ) 3 , which is of monoclinic ( P 2 1 / c ) crystal structure consisting of FeO 6 octahedra and MoO 4 tetrahedra interconnected through corner sharing oxygen atoms. It has been shown to be a promising cathode material for both Li and Na, not at least due to good thermal and structural stability. The structure is shown in the insert of Figure a.…”

Sodium-ion batteries (SIBs) have attracted increasing attention in the past decades, because of high overall abundance of precursors, their even geographical distribution, and low cost. Apart from inherent thermodynamic disadvantages, SIBs have to overcome multiple kinetic problems, such as fast capacity decay, low rate capacities and low Coulombic efficiencies. A special case is sodium super ion conductor (NASICON)-based electrode materials as they exhibit - besides pronounced structural stability - exceptionally high ion conductivity, rendering them most promising for sodium storage. Owing to the limiting, comparatively low electronic conductivity, nano-structuring is a prerequisite for achieving satisfactory rate-capability. In this review, we analyze advantages and disadvantages of NASICON-type electrode materials and highlight electrode structure design principles for obtaining the desired electrochemical performance. Moreover, we give an overview of recent approaches to enhance electrical conductivity and structural stability of cathode and anode materials based on NASICON structure. We believe that this review provides a pertinent insight into relevant design principles and inspires further research in this respect.

The demand for electrical energy storage (EES) is ever increasing, which calls for better batteries. NASICON-structured materials represent a family of important electrodes due to its superior ionic conductivity and stable structures. A wide range of materials have been considered, where both vanadium-based and titanium-based materials are recommended as being of great interest. NASICON-structured materials are suitable for both the cathode and the anode, where the operation potential can be easily tuned by the choice of transition metal and/or polyanion group in the structure. NASICON-structured materials also represent a class of solid electrolytes, which are widely employed in all-solid-state ion batteries, all-solid-state air batteries, and hybrid batteries. NASICON-structured materials are reviewed with a focus on both electrode materials and solid-state electrolytes.

“…Figure 4b shows the second-cycle charge− discharge voltage profiles of HoMS Fe 2 (MoO 4 ) 3 and a nanosheet at a current density of 0.1 C (1 C = 91 mA g −1 ) in a potential range from 1.5 to 4.0 V. In the discharge process, the potential quickly falls to the 2.74 and 2.59 V plateau and then declines to the cutoff voltage of 1.5 V, similar to previous reports. 45 The second-cycle specific capacity of the NS and single-shelled, double-shelled, triple-shelled, quadruple-shelled, and quintuple-shelled hollow spheres were 90.46, 92.21, 93.96, 94.73, 95.10, and 99.03 mAh g −1 , respectively. The larger specific capacity than the theoretical value of 91 mAh g −1 could be contributed by the capacitive behavior.…”

Multishelled binary metal oxide, which can exert a synergetic effect of different oxides, is a promising electrochemical electrode material. However, it is challenging to synthesize this kind of binary metal oxide due to the severe hydrolysis and/or precipitation reactions of the precursors between cations and anions of different metals. Herein, by using citric acid as a chelating agent to inhibit hydrolysis and precipitation, a series of multishelled binary metal oxide hollow spheres (Fe 2 (MoO 4 ) 3 , NiMoO 4 , MnMoO 4 , CoWO 4 , MnWO 4 , etc.) were obtained via coabsorption of negative and positive metal ions. In addition, the chelation between a metal ion and citric acid is systematically validated by NMR, MS, Raman, and UV−vis. In particular, multishelled Fe 2 (MoO 4 ) 3 hollow spheres show excellent electrochemical performance as cathode material for sodium-ion batteries benefited from their structural superiorities. Especially, the quintuple-shelled Fe 2 (MoO 4 ) 3 hollow sphere shows the highest specific capacity (99.03 mAh g −1 ) among all Fe 2 (MoO 4 ) 3 hollow spheres, excellent stability (85.6 mAh g −1 was retained after 100 cycles at a current density of 2.2 C), and outstanding rate capability (67.4 mAh g −1 can be obtained at a current density of 10 C). This general approach can be extended to the synthesis of other multishelled multielement metal oxides and greatly enrich the diversity of hollow multishelled structures.
