“…As a typical representative of phosphates, NASICON‐type NVP exhibits a high working voltage plateau (≈4.0 V) as well as relatively high reversible capacity (≈118 mAh g −1 ) and good thermal stability (450 °C) . Kim and coworkers synthesized a highly crystalline graphene/NVP composite first as a cathode material for rechargeable sodium ion batteries using a simple combined sol–gel and solid‐state reaction .…”

renewable energy is imperative and of great significance for human beings. As the ideal alternatives, green energy sources including wind, solar energy, water, and tide power have been widely applied in modern industry successfully, but their intermittent and variability feature cannot support all-weather utilization. [3][4][5] Hence, developing high-efficiency energy storage and conversion technology is a powerful measure to solve the above problems. Currently, there has been great interest in developing/refining high-performance electrochemical energy storage (EES) devices such as batteries, supercapacitors, and fuel cells. Among various EES technologies, secondary rechargeable batteries (e.g., lead-acid batteries, Ni-Cd batteries, nickel-metal hydride batteries, and lithium/sodium ion batteries) have been extensively studied and play an important role in modern electronics and transportation. [6] Typically, since the successful commercialization of lithium ion batteries (LIBs) by Sony in 1991, we have entered into an era of LIBs due to their high working voltage, long cycles, low self-discharge, large energy density, and low maintenance. [7] After rapid development over the past decades, the fabrication techniques and performance of LIBs have made great progress and matured significantly to be used as main power source for sophisticated electronics, [8] hybrid electric vehicles, and pure electric vehicles. [1,9] However, the high Scrupulous design and smart hybridization of bespoke electrode materials are of great importance for the advancement of sodium ion batteries (SIBs). Graphene-based nanocomposites are regarded as one of the most promising electrode materials for SIBs due to the outstanding physicochemical properties of graphene and positive synergetic effects between graphene and the introduced active phase. In this review, the recent progress in graphene-based electrode materials for SIBs with an emphasis on the electrode design principle, different preparation methods, and mechanism, characterization, synergistic effects, and their detailed electrochemical performance is summarized. General design rules for fabrication of advanced SIB materials are also proposed. Additionally, the merits and drawbacks of different fabrication methods for graphene-based materials are briefly discussed and summarized. Furthermore, multiscale forms of graphene are evaluated to optimize electrochemical performance of SIBs, ranging from 0D graphene quantum dots, 2D vertical graphene and reduced graphene oxide sheets, to 3D graphene aerogel and graphene foam networks. To conclude, the challenges and future perspectives on the development of graphene-based materials for SIBs are also presented.

“…Furthermore, lithium resource is limited in nature. It is necessary to develop low cost and high storage performance sodium ion batteries (SIBs) to satisfy the energy demand (Li et al, 2017a; Zhu et al, 2017; Chen et al, 2018a). Sodium is rich on the earth, and possesses similar physical and chemical properties as lithium (Qu et al, 2014; Jiang et al, 2015; Wang et al, 2015b; Zhang et al, 2015a, 2017a; Fang et al, 2016; Xu et al, 2016c; Leng et al, 2017).…”

SnS2 nanosheets/reduced graphene oxide (rGO) composite was prepared by reflux condensation and hydrothermal methods. In this composite, SnS2 nanosheets in-situ grew on the surface of rGO nanosheets. The SnS2/rGO composite as anode material was investigated both in lithium ion battery (LIB) and sodium ion battery (SIB) systems. The capacity of SnS2/rGO electrode in LIB achieved 514 mAh g−1 at 1.2 A g−1 after 300 cycles. Moreover, the SnS2/rGO electrode in SIB delivered a discharge capacity of 645 mAh g−1 at 0.05 A g−1; after 100 cycles at 0.25 A g−1, the capacity retention still keep 81.2% relative to the capacity of the 6th cycle. Due to the introduction of rGO in the composite, the charge-transfer resistance became much smaller. Compared with SnS2/C electrode, SnS2/rGO electrode had higher discharge capacity and much better cycling performance.

“…Among them, mesoporous microsphere structure of Na V 2 (PO 4 ) 3 /carbon (NVP/C) nanocomposites is considered to be one of the most effective ways for high energy/power density SIBs [14,15]. Considerable research efforts have been devoted to the fabrication of NVP/C mesoporous microspheres, in which many synthesis methods, such as the solid state synthesis [16], the sol-gel method [17,18], the aerosol synthesis [19] and spray-drying method [20][21][22][23], have been investigated. However, those methods cannot satisfy the requirement for high power density and long cycle life of SIB cathodes.…”
