“…The excellent electrochemical performance of Na 0.44 MnO 2 nanowires benefits from shortened diffusion path of Na ions and stable tunnel structure. After that, a lot of Na 0.44 MnO 2 materials with different nanostructures have been realized [21][22][23]. The sodium storage mechanism has also been studied.…”

Grid-scale energy storage systems with low-cost and high-performance electrodes are needed to meet the requirements of sustainable energy systems. Due to the wide abundance and low cost of sodium resources and their similar electrochemistry to the established lithium-ion batteries, sodium-ion batteries (SIBs) have attracted considerable interest as ideal candidates for grid-scale energy storage systems. In the past decade, though tremendous efforts have been made to promote the development of SIBs, and significant advances have been achieved, further improvements are still required in terms of energy/ power density and long cyclic stability for commercialization. In this review, the latest progress in electrode materials for SIBs, including a variety of promising cathodes and anodes, is briefly summarized. Besides, the sodium storage mechanisms, endeavors on electrochemical property enhancements, structural and compositional optimizations, challenges and perspectives of the electrode materials for SIBs are discussed. Though enormous challenges may lie ahead, we believe that through intensive research efforts, sodium-ion batteries with low operation cost and longevity will be commercialized for large-scale energy storage application in the near future.

“…As novel solvents ILs possess structure‐adjustable feature to satisfy practical requirements which can promote their applications for numerous fields, such as gas separation, chemical reactions, catalysis, and so on . Recent researches have shown that electrolytes based on ILs with a certain proportion of dissolved sodium salts (Na‐salts) can enhance the cycling performance and capacity . However, the studies on ILs‐based Na + electrolytes are insufficient because the fluidity of ILs can also cause leakage which lead to safety problems.…”

Developing stable conductive materials with high conductivity for sodium ion (Na+) batteries attracts ever‐increasing attention. In this work, MOF‐based solid Na+‐conducting composites functionalized by ionic liquids (ILs) were explored through introducing five kinds of ILs and their corresponding sodium salts into the pores of MIL‐101‐SO3Na. The pore‐filling fraction of MIL‐101‐SO3Na was established and revealed as a key factor to enhance the ionic conductivity of the composites. Na‐salts could further improved the conductivity by increasing the number of conductive ions. Furthermore, all ILs and Na‐salts@MIL‐101‐SO3Na hybrid composites showed sharply enhanced ionic conductivity and displayed low activation energy. Particularly, as the pore‐filling faction elevating to 96.94 % with [Emim][BF4] and NaBF4 in the pores of MIL‐101‐SO3Na the ionic conductivity reached up to 1.32×10−2 S cm−1 and stabilized within 30 days at 150 °C. This study on Na+‐conduction in a MOF‐based system functionalized by ILs, providing guidance for exploring new solid ionic conducting materials.

“…[1,2] The main incentive for using NIBs is the abundance, globald istribution, and low cost of sodium precursors. For example, although there has been decent progress on cathode materials, including layered oxides, polyanionic compounds, Prussian blue analogues, and organic compounds, [4][5][6][7][8] finding ag ood anode is relativelyc hallenging because the commonlyu sed LIB graphite anode has poor Na + storage capability.

SnO2@CMK‐8 composite, a highly promising anode for Na‐ion batteries (NIBs), was incorporated with polyvinylidene difluoride (PVDF), sodium carboxymethylcellulose (NaCMC), sodium polyacrylate (NaPAA), and NaCMC/NaPAA mixed binders to optimize the electrode sodiation/desodiation properties. Synergistic effects between NaCMC and NaPAA led to the formation of an effective protective film on the electrode. This coating layer not only increased the charge–discharge Coulombic efficiency, suppressing the accumulation of solid–electrolyte interphases, but also kept the SnO2 nanoparticles in the CMK‐8 matrix, preventing the agglomeration and removal of oxide upon cycling. The adhesion strength and stability towards the electrolyte of the binders were evaluated. In addition, the charge–transfer resistance and apparent Na+ diffusion of the SnO2@CMK‐8 electrodes with various binders were examined and post‐mortem analyses were conducted. With NaCMC/NaPAA binder, exceptional electrode capacities of 850 and 425 mAh g−1 were obtained at charge–discharge rates of 20 and 2000 mA g−1, respectively. After 300 cycles, 90 % capacity retention was achieved. The thermal reactivity of the sodiated electrodes was studied by using differential scanning calorimetry. The binder effects on NIB safety, in terms of thermal runaway, are discussed.
