Grid‐scale energy storage systems (ESSs) that can connect to sustainable energy resources have received great attention in an effort to satisfy ever‐growing energy demands. Although recent advances in Li‐ion battery (LIB) technology have increased the energy density to a level applicable to grid‐scale ESSs, the high cost of Li and transition metals have led to a search for lower‐cost battery system alternatives. Based on the abundance and accessibility of Na and its similar electrochemistry to the well‐established LIB technology, Na‐ion batteries (NIBs) have attracted significant attention as an ideal candidate for grid‐scale ESSs. Since research on NIB chemistry resurged in 2010, various positive and negative electrode materials have been synthesized and evaluated for NIBs. Nonetheless, studies on NIB chemistry are still in their infancy compared with LIB technology, and further improvements are required in terms of energy, power density, and electrochemical stability for commercialization. Most recent progress on electrode materials for NIBs, including the discovery of new electrode materials and their Na storage mechanisms, is briefly reviewed. In addition, efforts to enhance the electrochemical properties of NIB electrode materials as well as the challenges and perspectives involving these materials are discussed.

“…However, when used as the negative electrode in SIBs, graphite is electrochemically inactive, and only a limited number of sodium ions can be intercalated into graphite. [5] In recent years, many materials, including carbonaceous materials, [6][7][8][9][10][11][12][13][14][15] as well as Na 2 Ti 3 O 7 , [16][17][18][19][20] Na 4 Ti 5 O 12 , [21] TiO 2 , [22][23][24] SnO 2 , [25,26] and alloys, [27][28][29][30][31] Moreover, to demonstrate the practical applicability of HC electrode, a full cell was fabricated using NaCrO 2 as the positive electrode, and its performance was investigated for the first time at 90 ºC.…”

Please cite this article as: Changsheng Ding, Toshiyuki Nohira, Rika Hagiwara, Atsushi Fukunaga, Shoichiro Sakai, Koji Nitta, Electrochemical performance of hard carbon negative electrodes for ionic liquid-based sodium ion batteries over a wide temperature range, Electrochimica Acta http://dx.Abstract Sodium ion batteries (SIBs) have been attracting much attention as promising next-generation energy storage devices for large-scale applications. The major safety issue with SIBs, which arises from the flammability and volatility of conventional organic solvent-based electrolytes, is resolved by adopting an ionic liquid (IL) electrolyte. However, there are only a few reports on the study of negative electrodes in ILs. Here, we report the electrochemical performance of a hard carbon (HC) negative electrode in Na[FSA]-[C 3 C 1 pyrr][FSA] (FSA = bis(fluorosulfonyl)amide, C 3 C 1 pyrr = N-methyl-N-propylpyrrolidinium) IL over a wide temperature range of −10 ºC to 90 ºC.High-temperature operation, which is realized for the first time by using an IL, can take full advantage of the high capacity of HC even at a very high discharge rate of 1000 mA (g-HC) -1 : the discharge capacity is 230 mAh (g-HC) -1 at 90 ºC and 25 mAh (g-HC) -1 at 25 ºC. Moreover, surprisingly stable cycleability is observed for the HC electrode at 90 ºC, i.e. a capacity retention ratio of 84% after 500 cycles. Finally, a high full-cell voltage of 2.8 V and stable full-cell operation with Coulombic efficiency higher than 99% are achieved for the first time when using NaCrO 2 as the positive electrode at 90 ºC.

“…Considering the anode materials, few suitable hosts are reported due to the unsuitable application of Li-ion anode materials when used in Na-ion batteries [10][11][12][13]. For instance, graphite, the most common commercial anode material in Li-ion batteries, cannot be used as the Na-ion anode since Na atoms are difficult to intercalate between the narrow van der Walls gap of graphite sheets [14,15].…”

A composite of transition metal oxide Co 3 O 4 and multiwalled carbon nanotubes (MCNTs) was applied as an anode material for sodium-ion batteries via a simply modified solid-state reaction and sonication method. The as-prepared Co 3 O 4 /MCNTs composite shows improved electrochemical performance than bare Co 3 O 4 owing to the Co 3 O 4 /MCNTs nanostructure that benefits Na ion and electronic transport together with buffering the large volume change of Co 3 O 4 during charging and discharging process. Additionally, the Na-storage behavior and the original capacity loss of Co 3 O 4 based on the conversion reaction have been investigated through cyclic voltammogram, X-ray diffraction, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and selected area electron diffraction. It is firstly demonstrated that in discharge state, Co 3 O 4 particles initially react with Na to produce CoO and then is further reduced to nanosized Co in an amorphous sodium oxides matrix. In the charge process, Co nanoparticles were partially oxidized to Co 3 O 4 , the other part of the CoO remain leading capacity loss. These results offer new insights into the electrochemical process of transition metal-based anode materials for Na-ion batteries.
