“…The SbNP@C electrodes were produced through a cheap, simple and scalable electrospinning process, which showed an initial capacity of 422 mAh g −1 and retained 350 mAh g −1 after 300 cycles. Moreover, because of the efficient 1D Na + transport pathway and the highly conductive network of SbNP@C, the electrode preserved high overall capacities even when cycled at high current densities, extending its usability to high-power applications [147].…”

Sodium-ion batteries have been emerging as attractive technologies for large-scale electrical energy storage and conversion, owing to the natural abundance and low cost of sodium resources. However, the development of sodium-ion batteries faces tremendous challenges, which is mainly due to the difficulty to identify appropriate cathode materials and anode materials. In this review, the research progresses on cathode and anode materials for sodium-ion batteries are comprehensively reviewed. We focus on the structural considerations for cathode materials and sodium storage mechanisms for anode materials. With the worldwide effort, high-performance sodium-ion batteries will be fully developed for practical applications.

Rechargeable Na metal batteries have gained great recognition as a promising candidate for nextgeneration battery systems, largely on the basis of the high theoretical specific capacity (1165 mAh g −1 ) and low redox potential (−2.71 V versus the standard hydrogen electrode) of Na metal, as well as the natural abundance of Na and the similarities between these batteries and lithium batteries. Much effort has been dedicated to improving the electrochemical performance of rechargeable Na batteries through the development of high-performance cathodes, anodes, and electrolytes. Nevertheless, the practical application of Na metal batteries is quite challenging because the high chemical and electrochemical reactivity of Na metal electrodes with organic liquid electrolytes leads to low Coulombic efficiencies and limited cycling performance. Severe electrolyte decomposition at the Na metal electrode results in the formation of a resistive and non-uniform surface film, leading to dendritic Na metal growth. To control the Na metal electrode-electrolyte interface for high performance Na metal batteries, considerable efforts have been made to find electrolyte systems that are stable at the Na metal electrode. Using fluoroethylene carbonate (FEC) as an electrolyte additive for in situ formation of an artificial solid electrolyte interphase (SEI) layer could stabilize the anodeelectrolyte interface. However, the FEC-derived SEI acted as a resistive layer, impeding the sodiation-desodiation process and reducing the reversible capacity of the anodes. Finding new electrolyte systems that are stable at the Na metal electrode and possess high oxidation durability at high-voltage cathodes is necessary for the development of high-performance Na metal batteries.Very recently, there are some papers which introduced significant breakthroughs in lithium battery electrolytes. It is reported that improving the cycling efficiency of lithium plating/stripping and suppressing the formation of dendritic lithium metal is possible by using highly concentrated electrolytes, even at high current densities. And it is also reported that highly concentrated electroltyes can inhibit the dissolution of transition metals out of the 5 V-class LiNi0.5Mn1.5O4 (LNMO) electrode material and the corrosion of the Al current collector at high voltage conditions. After reading these papers, I thought that applying this highly concentrated electrolyte system to sodium metal batteries could be the solution for improvements in the electrochemical performance of Na metal anodes coupled with high-voltage cathodes.In this study, an ultraconcentrated electrolyte composed of 5 M sodium bis(fluorosulfonyl)imide in 1,2-dimethoxyethane will be introduced for Na metal anodes coupled with high-voltage cathodes.Using this electrolyte, a very high Coulombic efficiency of 99.3% at the 120 th cycle for Na plating/stripping is obtained in Na/stainless steel (SS) cells, with highly reduced corrosivity toward Na metal and high oxidation durability (over 4.9 V versus Na/Na ...

Yang et al and Kang et al also achieve good SIB performance by Sb/C hybrid respectively [10,11].
