“…3, the cells start to show good electrochemical performance in terms of cycling stability as well as coulombic efficiency (≥ 90 %, ≥ 85 % for NaClO 4 in PC electrolyte) after 20 discharge-charge cycles. However, during the initial cycles (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20), these electrochemical parameters, particularly the capacity retention, were much lower.…”

“…To this end, a variety of electrode materials [1][2][3][4], cathode and anode, and electrolytes [1,2,5,6] for SIBs have been investigated, mainly, in the last two years. The results of the research in the field of cathode materials, several of them obtained by the simple replacement of lithium by sodium in the analogue compound, appear promising with a number of layered transition metal oxides, phosphates and fluorophosphates showing acceptable reversible capacity, stability and relatively high operating potentials [1,4].…”

“…Although lithium-ion batteries have been widely used in portable electronic devices and are considered to be the best choice for electric vehicles, the increasing cost and limited resources of lithium may restrict their application in large-scale energy storage systems [3][4][5] . Sodium-ion batteries have attracted extensive attentions for such large-scale applications in both scientific and technological aspects because of the abundance of sodium resources and potential low cost as well as the similarity of sodium-ion storage device to those of as lithium-ion batteries [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] .…”

Ti-substituted tunnel-type Na0.44MnO2 oxide as a negative electrode for aqueous sodium-ion batteries

The aqueous sodium-ion battery system is a safe and low-cost solution for large-scale energy storage, because of the abundance of sodium and inexpensive aqueous electrolytes. Although several positive electrode materials, for example, Na 0.44 MnO 2 , were proposed, few negative electrode materials, for example, activated carbon and NaTi 2 (PO 4 ) 3 , are available. Here we show that Ti-substituted Na 0.44 MnO 2 (Na 0.44 [Mn 1-x Ti x ]O 2 ) with tunnel structure can be used as a negative electrode material for aqueous sodium-ion batteries. This material exhibits superior cyclability even without the special treatment of oxygen removal from the aqueous solution. Atomic-scale characterizations based on spherical aberration-corrected electron microscopy and ab initio calculations are utilized to accurately identify the Ti substitution sites and sodium storage mechanism. Ti substitution tunes the charge ordering property and reaction pathway, significantly smoothing the discharge/charge profiles and lowering the storage voltage. Both the fundamental understanding and practical demonstrations suggest that Na 0.44 [Mn 1-x Ti x ]O 2 is a promising negative electrode material for aqueous sodium-ion batteries.

“…While, the scientific issues of poor cyclability for the anode are assigned to the large volume changes during charging/discharging, the low electronic conductivity of the intrinsic material, and the sluggish kinetics. 20,[23][24][25] To pursue the strict requirements on the desired anode, various interesting materials have been investigated based on intercalation compounds, [26][27][28][29][30] metallic alloys, [31][32][33][34][35] and organic chemicals. [36][37][38] Among the intercalation compounds for the anode, metallic vanadates have been considered for a long time, because they display special crystal structure and electrochemical stability.…”

Electrochimica Acta, Electrochemically active, novel layered m-ZnV2O6 nanobelts for highly rechargeable Na-ion energy storage AbstractElectrode materials with a three-dimensional (3D) layered framework and excellent electrochemical stability can provide a new avenue for enhancing the overall performance of promising sodium ion batteries. Here, we show that layered monoclinic (m) -ZnV2O6 nanobelts with high chemical activity for Na-ion energy storage have been effectively fabricated via a rapid microwave irradiation method over the reaction time of 8 h, in which the fabricating efficiency is 24.5 times greater in comparison with the traditional hydrothermal method. The morphology and phase evolutions were verified by means of X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. This study also proposes the "topotactic transformationOstwald ripening" mechanism in layered m-ZnV2O6 nanobelts, from one-dimensional (1D) m-Zn2V2O7 with tunnel structure to a 3D m-ZnV2O6 layered structure. In particular, the m-ZnV2O6 nanobelt anode exhibited a high discharge capacity of 480.5 mAh g-1 at a current density of 10 mA g-1, and maintained the considerable discharge capacity of 246.9 mAh g-1 at the 100th cycle. The very preliminary results are promising and confirming that layered metallic vanadium can give a new insight into designing novel anode materials for high-efficiency energy storage in sodium ion batteries.
