“…The unique nanostructure transformed the electrochemically inert maricite NaFePO 4 into a highly active amorphous phase because of the increased active sites, showing a capacity of 87.3 mAh g −1 after 1000 cycles at 2 C under −20°C. [96] In the past decades, many other types of sodium phosphates have been reported, especially the NASICONtype polyanionic compounds, such as Na 3 V 2 (PO 4 ) 3 . [97,98] As shown in Figure 6A, the corner-sharing of PO 4 tetrahedra and VO 6 octahedra in the Na 3 V 2 (PO 4 ) 3 structure builds a stable 3D open framework, providing sufficient interstitial space to facilitate the transportation of Na + ions.…”

In recent years, considerable attention has been focused on the development of sodium-ion batteries (SIBs) because of the natural abundance of raw materials and the possibility of low cost, which can alleviate the concerns of the limited lithium resources and the increasing cost of lithium-ion batteries. With the growing demand for reliable electric energy storage devices, requirements have been proposed to further increase the comprehensive performance of SIBs. Especially, the low-temperature tolerance has become an urgent technical obstacle in the practical application of SIBs, because the low operating temperature will lead to sluggish electrochemical reaction kinetics and unstable interfacial reactions, which will deteriorate the performance and even cause safety issues. On the basis of the charge-storage mechanism of SIBs, optimization of the composition and structure of electrolyte and electrode materials is crucial to building SIBs with high performance at low temperatures. In this review, the recent research progress and challenges were systematically summarized in terms of electrolytes and cathode and anode materials for SIBs operating at low temperatures. The typical full-cell configurations of SIBs at low temperatures were introduced to shed light on the fundamental research and the exploitation of SIBs with high performance for practical applications.

“…First, PAA, Li 2 CO 3 , and IPA were added into deionized water to form the PAA-Li nanospheres (NSs). 27,28 Subsequently, FePO 4 was generated on the network of the PAA-Li NS after adding NH 4 H 2 PO 4 and FeCl 2 •4H 2 O. The product was annealed at 350 °C for 5 h and then 700 °C for 10 h under an argon atmosphere to carbonize the PAA shell and afford PNCsLFP.…”

The lithium iron phosphate battery (LiFePO 4 or LFP) does not satisfactorily deliver the necessary high rates and low temperatures due to its low Li + diffusivity, which greatly limits its applications. The solid-solution reaction, compared with the traditional two-phase transition, needs less energy, and the lithium ion diffusivity is also higher, which makes breaking the barrier of LFP possible. However, the solid-solution reaction in LFP can only occur at high rates due to the lattice stress caused by the bulk elastic modulus. Herein, pomegranate-like LFP@C nanoclusters with ultrafine LFP@C subunits (8 nm) (PNCsLFP) were synthesized. Using in situ X-ray diffraction, we confirmed that PNCsLFP can achieve complete solid-solution reaction at the relatively low rate of 0.1C which breaks the limitation of low lithium ion diffusivity of the traditional LFP and frees the lithium ion diffusivity from temperature constraints, leading to almost the same lithium ion diffusivities at room temperature, 0, −20, and −40 °C. The complete solid-solution reaction at all rates breaks the shackles of limited lithium ion diffusivity on LFP and offers a promising solution for next-generation lithium ion batteries with high rate and low temperature applications.

“…Liu et al designed highly dispersed maricite NaFePO 4 nanoclusters with ultrafine subunits (3 nm) illustrated in Figure 5g, shortening Na + /electron diffusion pathways and providing high electrical conductivity, leading to high rate property and outstanding low-temperature application. [29] Besides the electrochemical and mechanochemical methods, laser irradiation was also found to enable phase transition from maricite NaFePO 4 to amorphous NaFePO 4 . [30] Interestingly, anionic (O 2− ) redox reactions are evidently visible in triphylite-NaFePO 4 and maricite-NaFePO 4 based on firstprinciples calculations and analysis of Bader charges.…”

development, it is urgent to rummage and exploit renewable energy for instance solar energy, wind energy, nuclear energy, and tidal energy, etc. Large-scale energy storage systems (ESSs) are necessary and critical to integrate the above-mentioned intermittent energy into a continuous energy system, among which the electrochemical energy storage device is the most convenient, stable, and effective way for grid-connected forthputting. [2] Lithiumion batteries have been commercialized in the fields of electric vehicles, portable electronic devices, and electric tools, etc. since the 1990s. [3] Notably, lithium iron phosphate (LiFePO 4 ), one of the most important cathode materials for LIBs, is a potential candidate for large-scale energy storage due to its long lifespan, low toxicity, and outstanding thermal stability.
