“…By the 1980s, West et al [7] reported the insertion of sodium in the α-V 2 O 5 and Na 1+ x V 3 O 8 lamellar materials and in the β-Na x V 2 O 5 tunnel structure. These materials, and more particularly α-V 2 O 5 , were reinvestigated more recently and delivered capacities close to the theoretical capacity expected for the formation of Na 2 V 2 O 5 based on the redox couple V 5+ /V 4+ [8,9,10]. We also cite the work of Pereira-Ramos group on the synthesis of new sodium vanadium bronzes, which have been studied as cathode material for NIBs [11,12,13].…”

The search for new materials that could be used as electrode material for Na-ion batteries is one of the most challenging issues of today. Many transition metal oxide families as well as transition metal polyanionic frameworks have been proposed over the last five years. In this work, we report the sodium extraction from Na2V3O7, which is a tunnel type structure built of [V3O7]2−∞ nanotubes held by sodium ions. We report a reversible charge capacity of 80 mAh/g at 2.8 V vs. Na+/Na due to the V5+/V4+ redox activity. No oxygen redox activity has been observed for this material nor for the vanadium (5+) oxide Na4V2O7.

Simple defect modification is a powerful means to improve material intercalation capabilities. It has received considerable interest lately as it can directly alter both the chemical and structural characteristics; techniques of note include cationic disordering, amorphization, doping, partial cation reduction, and manipulation of intrinsic defects. Defects can reduce the stress and the electrostatic repulsion between adjacent oxygen layers, which can directly alter the migration energy and diffusion barriers the alkali ion must overcome during intercalation. Complementary to experimental observations, theoretical predictions are paramount to developing a detailed understanding of material-defect chemistry. This focus review aims to demonstrate that the optimized design of stable intercalation compounds could lead to substantial improvements in energy-storage applications by overcoming intrinsic limitations.

“…[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.
