“…Likewise, a Sn-Cu nanocomposite that exhibits a capacity of 420 mA h g −1 for 100 cycles was suggested. [ 427 ] In addition, 3D viral nanoforests, which deliver a capacity of 405 mA h g −1 at 150 cycles, were introduced, and the stable cycle life was attributed to the nanostructure, which buffers volume expansion and suppresses Sn aggregation.

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.

“…8 To this end, researchers have proposed a number of high-capacity sodium host materials (negative electrode) involving either carbon or group IVA and VA elements that form intermetallic compounds with Na. [9][10][11][12][13] The alloying compounds demonstrate high first cycle Na-storage capacities, such as Na 15 Sn 4 (847 mAhg -1 ), Na 15 Pb 4 (485 mAhg -1 ), Na 3 Sb (600 mAhg -1 ) and Na 3 P (2560 mAhg -1 ), respectively. However, this comes at the cost of very high volume change upon Na-insertion (as much as 500 % in some cases), resulting in formation of internal cracks, loss of electrical contact, and eventual failure of the electrode (particularly for thick electrodes).…”

We study the synthesis, electrochemical and mechanical performance of layered freestanding papers composed of acid exfoliated few layer molybdenum disulfide (MoS 2 ) and reduced graphene oxide (rGO) flakes for use as a self-standing flexible electrode in sodium ion batteries. Synthesis was achieved through vacuum filtration of homogenous dispersions consisting of varying wt. % of acid treated MoS 2 flakes in GO in DI water, followed by thermal reduction at elevated temperatures. The electrochemical performance of the crumpled composite paper (at 4 mg.cm -2 ) was evaluated as counter electrode against pure Na foil in a half-cell configuration. The electrode showed good Na cycling ability with a stable charge capacity of approx.230 mAh.g -1 with respect to total weight of the electrode with coulombic efficiency reaching approx. 99 %. In addition, static uniaxial tensile tests performed on crumpled composite papers showed high average strain to failure reaching approx. %.KEYWORDS: TMDC, sodium battery, freestanding electrode, graphene, MoS 2 2 Lithium ion batteries (LIBs) have been extensively studied for energy-storage applications like portable electronic devices and electric vehicles. [1][2][3] However, concerns over the cost, safety and availability of Li reserves 4 for large-scale applications involving renewable energy integration and the electrical grid have to be answered. In this regard, sodium ion batteries (SIBs) have drawn increasing attention because in contrast to lithium, 5-7 sodium resources are practically inexhaustible and evenly distributed around the world while the ion insertion chemistry is largely identical to that of lithium. Also, from electrochemical point of view, sodium has a very negative redox potential (-2.71 V, vs. SHE) and a small electrochemical equivalent (0.86 gAh -1 ), which make it the most advantageous element for battery applications after lithium. However, many challenges remain before SIBs can become commercially competitive with LIBs. For instance, Na ions are about 55% larger in radius than Li-ions, which makes it difficult to find a suitable host material to allow reversible and rapid ion insertion and extraction. 8 To this end, researchers have proposed a number of high-capacity sodium host materials (negative electrode) involving either carbon or group IVA and VA elements that form intermetallic compounds with Na. [9][10][11][12][13] The alloying compounds demonstrate high first cycle Na-storage capacities, such as Na 15 Sn 4 (847 mAhg -1 ), Na 15 Pb 4 (485 mAhg -1 ), Na 3 Sb (600 mAhg -1 ) and Na 3 P (2560 mAhg -1 ), respectively. However, this comes at the cost of very high volume change upon Na-insertion (as much as 500 % in some cases), resulting in formation of internal cracks, loss of electrical contact, and eventual failure of the electrode (particularly for thick electrodes). 14 Novel nanostructured designs that can accommodate large volumetric strains need further exploration.
