Research on electrochemical Na intercalation in battery system has been reported since the early 1980s but Na-ion batteries are not commercialized so far though studies on Li-ion batteries have been reported since the late 1970s and the practical batteries have been extensively utilized for portable device applications in the world since 1991. Now, targeted application of research and development for rechargeable batteries has changed toward realization of the sustainable energy society. With the change in social situation and development of the battery technology, studies on Na-ion batteries have been attracted significant interests since 2010. Although research interests of the electrode materials for Na-ion batteries are evoked in many researchers, advantages, disadvantages, and issues are not fully discussed for realizing the commercialization of Na-ion batteries. In this article, practical issues and perspective are reviewed on the basis of mainly our experimental experiences, know-how, and results, and the future direction is proposed to overcome the issues and to challenge the advanced performance. Power storage technology has been dramatically developed since rechargeable lithium battery (LIB), which are often called a Li-ion battery as named by Sony Corp., was commercialized in 1991 and delivered great impact on economy with tapping into new markets. A high-energy powerful LIB for portable electronic devices such as lap top computers and mobile phones is one of the best examples, and indeed they become essential tools for our life. Thanks for the great research achievement, the price of the battery pack has been declining for more than 20 years, and LIBs are now able to be installed in power system for hybrid electric vehicles (HEV) and battery electric vehicles (BEV) with relatively affordable price. Continuous effort has been devoted on the development of LIBs toward higher-power/higherenergy performance, and they now become promising candidates for being a part of grid-scale energy storage incorporated with wind and solar power systems. When it comes to large-scale power system more than that for electric vehicles, the priority in research is shifted to production cost from performance and thus minor-metal free or low-cost materials that can be derived from more abundant resources have become increasingly desirable. Although LiMn 2 O 4 , LiFePO 4 , and LiNi x Mn y Co z O 2, which are utilized in HEV and BEV instead of costly LiCoO 2, are recognized as low cost materials, 1,2 lithium in the Earth's crust is unevenly distributed as minor-metal and consequently affecting to dependence on import of lithium resource and additionally to product costs. In contrast to lithium, sodium is unlimited in the Earth's crust and sea, and is one of the most abundant elements in the Earth's crust. Since the alternative to lithium is more desirable for realizing largescale power source and sodium is the second lightest alkali next to lithium, Na-ion batteries (NIBs) have attracted much attention as feasible technology ...

“…On the other hand, graphite is a frequently used anode material for LIBs because of its favorable layered structure, natural abundance and low cost. 47,48 Nevertheless, graphite is unable to fulfill the increasing demands for high-energy power sources owing to its low capacity (372 mAh g −1 ). Recently, several 2D TMDCs (including MoS 2 , MoSe 2 , WS 2 , WSe 2 , VS 2 , VS 4 and TiS 2 ) have been extensively explored as LIB anodes due to their favorable layered structure for ion/electron migration and chemical stability.…”

Rechargeable batteries are most important energy storage devices in modern society with the rapid development and increasing demand for handy electronic devices and electric vehicles. The higher surface-to-volume ratio two-dimensional (2D) materials, especially transition metal dichalcogenides (TMDCs) and transition metal carbide/nitrite generally referred as MXene, have attracted intensive research activities due to their fascinating physical/chemical properties with extensive applications. One of the growing applications is to use these 2D materials as potential electrodes for rechargeable batteries and electrochemical capacitors. This review is an attempt to summarize the research and development of TMDCs, MXenes and their hybrid structures in energy storage systems. The strong demand for futuristic energy-storage materials and devices are exceptionally increasing owing to the request of more powerful energy storage systems with excellent power density and better cycle lifetime.1,2 For this reason, serious efforts have been undertaken to improve the electrode performance to achieve significantly improved the capacity, high rate capability and longer cycle life.3 Recently, 2D materials (TMDCs and MXene) have attracted intensive research activities due to their potential for broad applications.4-6 TMDCs represent a family of layered materials MX 2 (where M = one layer of transition metal and X = chalcogens) as shown in Figure 1a. [7][8][9] Figure 1b represents, three main structural polytypes, 1T, 2H and 3R of TMDCs. All three polytypes have layered structures with six fold trigonal prismatic coordination of transition metal atoms by the chalcogens within the TMDC layers. The term 1T, 2H and 3R represents the presence of one (1), two (2) and three (3) layers in the tetragonal (T), hexagonal (H) and rhombohedral (R) unit cell respectively. Interestingly, TMDCs own varied electronic structure, thus possess insulating (HfS 2 ), semi-conducting (MoS 2 , WS 2 ), semi-metallic (VS 2 , TiS 2 ), and superconducting (TaSe 2 , NbSe 2 ) behaviors which make them more attractive. Figure 1c, represents the exfoliation process of bulk TMDCs by lithium, sodium or potassium ion intercalation into the interlayer space and form ion-intercalated compounds, which can be further sonicated in water or organic solvents to produce single/few layer TMDC dispersions. More excitingly, the layers of TMDCs are connected with weak van der Waals interactions which enable them to serve for wide range of energy applications including energy generator, 10 energy storage 11-14 and catalysis. [15][16][17][18][19] On the other hand, MXenes 20 are produced from the MAX phase which is defined with the composition M n+1 AX n , where M = transition metal (i.e. Ti, V, Cr, Nb), A = group A element (i.e. Al, In, Sn, Si), X = carbon/nitrogen, and n = 1-3. Careful inscription of the group-A element from the MAX phase resulting in the production of MXene 20-24 as shown in Figures 1d-1e. One of the most studied applications of these 2D materials is to use t...

“…Also, the electrochemical performance of carbon anode was found to be dramatically influenced by dissolving (transition) metal ions as additives, such as Mn ~+, Co s+, Cu 2+, Ni 2+, Zn2+0 Pb 2+ and Ag + [12] based on the structural modification of the electrode-electrolyte interface, which is one of the most important factors that determines the anode performance. A similar study wherein the addition of NaClO4 salt to the LiClO4 ethylene carbonate-diethyl carbonate electrolyte solution has been reported to improve the electrochemical behavior of graphite [12]. Having intrigued by the arguments discussed in the mentioned paper, an attempt to investigate the anode performance behavior of graphite based upon the addition of small amount of sodium salt in the electrolyte solution has been made.…”

Abstract. Despite the reported enhanced electrochemical behavior of graphite anodes due to the addition ofNaC104 salts in to the electrolytes used in lithium battery applications, a detailed investigation upon the effect of addition of NaPF0 salt in an electrolyte containing 1 M LiPF6 in 1:1 V/V EC:DEC has resulted in inferior electrochemical behavior of graphite, i.e., quite contrast to the reported behavior of improved effects of addition of NaCIO4 into 1 M LiC104 solution, the addition of 0.22 tool dm -3 NaPF 6 salt has been found to reduce the capacities of lithium-ion cells containing 1 M LiPF 6 in 1:1 V/V EC:DEC. Towards this study, cells fabricated with and without the addition of 0.22 mol dm -3 NaPF 6 in 1 M LiPF 6 (1:1 V/V EC:DEC) were subjected to a systematic charging at a constant C/10 rate and discharging of cells at four different rates, viz., C/5, C/2 and C rates at the end of every 5 cycles. The observed results of the charge-discharge studies up to 15 cycles are discussed in this preliminary communication.
