“…Dursun et al fabricated a SnO 2 @graphene/N‐doped carbon (SGN) structures by a fast microwave method and tested their SIBs performances. Additionally, N‐doped carbon is favorable in raising the electronic conductivity ensuing over 423 mAh g −1 capacity after 180 cycles at 0.2 C . Sridhar et al reported a hollow SnO 2 @C–RGO composite, introduced as anodes in SIBs resulting a high specific capacitance of 493.12 mAh g −1 , good rate capability, and retained 96.2% of the initial capacitance even after 150 cycles.…”

In the scenario of renewable clean energy gradually replacing fossil energy, grid‐scale energy storage systems are urgently necessary, where Na‐ion batteries (SIBs) could supply crucial support, due to abundant Na raw materials and a similar electrochemical mechanism to Li‐ion batteries. The limited energy density is one of the major challenges hindering the commercialization of SIBs. Alloy‐type anodes with high theoretical capacities provide good opportunities to address this issue. However, these anodes suffer from the large volume expansion and inferior conductivity, which induce rapid capacity fading, poor rate properties, and safety issues. Carbon‐based alloy‐type composites (CAC) have been extensively applied in the effective construction of anodes that improved electrochemical performance, as the carbon component could alleviate the volume change and increase the conductivity. Here, state‐of‐the‐art CAC anode materials applied in SIBs are summarized, including their design principle, characterization, and electrochemical performance. The corresponding alloying mechanism along with its advantages and disadvantages is briefly presented. The crucial roles and working mechanism of the carbon matrix in CAC anodes are discussed in depth. Lastly, the existing challenges and the perspectives are proposed. Such an understanding critically paves the way for tailoring and designing suitable alloy‐type anodes toward practical applications.

“…For the energy storage electrode materials, the microwave assisted method has been used to ultrafast assembly of the Mn 0.8 Co 0.2 CO 3 /graphene composite [9], SnO 2 /graphene composite for LIBs [82], and SnO 2 @graphene/N-doped carbons for SIBs [83]. The ultrafast and uniform heating effect of the microwave method should be due to the dielectric heating principle, under which the polar molecules in the microwave radiation could rotate in a high frequency, and thus generate thermal energies evenly across the samples, which benefits the synthesis with environmental friendship, low cost, low energy consumption as well as the porous structures that especially provide the quick transfer channels of the Li + /Na + cations in the rechargeable batteries.…”

As an intriguing two dimensional material, graphene has attracted intense interest due to its high stability, large carrier mobility as well as the excellent conductivity. The addition of graphene into the heterogeneous electrodes has been proved to be an effective method to improve the energy storage performance. In this chapter, the latest graphene based heterogeneous electrodes will be fully reviewed and discussed for energy storage. In detail, the assembly methods, including the ball-milling, hydrothermal, electrospinning, and microwave-assisted approaches will be illustrated. The characterization techniques, including the x-ray diffraction, scanning electron microscopy, transmission electron microscopy, electrochemical impedance spectroscopy, atomic force microscopy, and x-ray photoelectron spectroscopy will also be presented. The mechanisms behind the improved performance will also be fully reviewed and demonstrated. A conclusion and an outlook will be given in the end of this chapter to summarize the recent advances and the future opportunities, respectively.

“…[5][6][7][8][9][10][11][12] Tin oxide (e.g., SnO 2 ) is one of such metal oxides that can readily participate in conversion reactions, followed by alloying with both Li and Na. [13][14][15][16][17][18][19][20][21] Additionally, tin oxides are low-cost materials and they demonstrate a variety of properties including high theoretical capacity (both gravimetric and volumetric basis) and excellent safety. The typical electrochemical reactions of SnO 2 with Li and Na-ions are as follows: Though a total B8.4 mole of Li participates in the electrochemical reaction, the theoretical capacity of SnO 2 as a LIB anode is only 790 mA h g À1 .…”
