    Abstract As an anode material for sodium-ion batteries (SIBs), hard carbon (HC) presents high specific capacity and favorable cycling performance. However, high cost and low initial Coulombic efficiency (ICE) of HC seriously limit its future commercialization for SIBs. A typical biowaste, mangosteen shell was selected as a precursor to prepare low-cost and high-performance HC via a facile one-step carbonization method, and the influence of different heat treatments on the morphologies, microstructures, and electrochemical performances was investigated systematically. The microstructure evolution studied using X-ray diffraction, Raman, Brunauer-Emmett-Teller, and high-resolution transmission electron microscopy, along with electrochemical measurements, reveals the optimal carbonization condition of the mangosteen shell: HC carbonized at 1500 °C for 2 h delivers the highest reversible capacity of ∼330 mA h g

    Abstract Sodium-ion batteries are regarded as the most promising alternative candidates for lithium-ion batteries. Hard carbon, as a kind of anode materials, has been demonstrated to deliver high specific capacity and stable cycling performance. However, it is still difficult to strike the balance between the relatively high cost and the superior electrochemical performance. We successfully fabricated low-cost lignite-derived hard carbons (a-LCs) with easy scale-up method. The microstructure, morphology and surface information of the obtained a-LCs are evaluated by X-ray diffraction, Raman spectrum and Fourier transform infrared spectrometer. By changing carbonization temperature, a-LCs’ microstructure and defect composition can be tuned and quite different sodium-ion storage behaviors can be seen. When carbonization temperature increases, the carbon microcrystallites grow and defects decay, resulting in a decrease in defect absorption capacity and an increase in graphitic-like nanodomain intercalation capacity. Particularly, a-LC carbonized at 1200 °C (a-LC-1200) can deliver a high capacity of 256 mAh g−1 with the initial Coulombic efficiency of 82%. Besides, it also exhibits a superior rate performance of 210, 197, 180, 168 and 146 mAh g−1 at current rates of 1, 2, 5, 10 and 20C (defined that 1C = 200 mA g−1), respectively. It solves the above problems very well and displays great commercial value.

    Abstract Abundant flake-porous Na3Fe2(PO4)3 has been prepared via a simple spray drying method. As a cathode material in sodium-ion batteries (SIBs), the galvanostatic charge/discharge test results indicate that the initial reversible discharge specific capacity of the flake-porous Na3Fe2(PO4)3 electrode can reach to 100.8 mAh g–1 (about 93% of the theoretical capacity of 105 mAh g–1) under a current density of 10 mA g–1 (0.1 C) and the high rate capability at 500 mA g–1 (5 C) is up to 60 mAh g–1 after 1100 cycles. The in situ X-ray diffraction pattern and ex situ X-ray photoelectron spectroscopy results indicate that the charge/discharge processes of this cathode material go through a reversible electrochemical reaction of Na3Fe2(PO4)3/Na5Fe2(PO4)3. The outstanding electrochemical performance of Na3Fe2(PO4)3 is attributed to its [Fe2(PO4)3] “lantern unit”-stacked NASICON-type structure and two-dimensional (2D) porous-sheet morphology. The flake-porous Na3Fe2(PO4)3 cathode with a commercial hard carbon anode full cell shows an energy density of 76 Wh kg–1 and the maximum power density of up to 760 W kg–1. The full cell also shows excellent low-temperature performance even at −20 °C (40 mAh g–1 at 100 mA g–1). The outstanding electrochemical and low-temperature performances prove that this full cell is an ideal device for large-scale electrical energy storage (EES).

    Abstract A high-voltage sodium-ion full battery has been assembled based on Na6Fe5(SO4)8 sulfate structurally integrated with 5 wt% carbon nanotubes (NFS@5%CNTs) acting as the cathode material, with commercialized hard carbon (HC) as the anode material. This full NFS@5%CNTs//HC cell delivers a practical working voltage of 3.6 V and an impressive energy density approaching 350 W h kg−1, and it can retain a specific capacity of 61.8 mA h g−1 after 1000 cycles at 2C. The superior sodium storage performance of this example of a full battery is attributed to the Na6Fe5(SO4)8 cathode material, which is structurally integrated with a conductive CNT component. The CNT additive is tightly implanted and runs through the whole NFS bulk, improving the electrochemical performance of NFS@x%CNTs cathode materials during the reversible intercalation/deintercalation of sodium ions. The optimized CNT content for NFS@x%CNTs cathode materials is evaluated to be 5 wt%, resulting in high initial capacities of 110.2 and 86.4 mA h g−1 at 0.1 and 2C, respectively. This work introduces a new derivative of sodium iron sulfates to act as a high-energy cathode material for sodium ion batteries, together with offering an effective CNT-assisted method for enhancing electrochemical performance. A full sodium-ion battery is further developed with a high working voltage and high energy/power densities for practical large-scale applications.

    Abstract Sodium-ion batteries (SIBs) have been considered to be potential candidates for next-generation low-cost energy storage systems due to the low cost and abundance of Na resources. However, it is a big challenge to find suitable anode materials with low cost and good performance for the application of SIBs. Hard carbon could be a promising anode material due to high capacity and expectable low cost if originating from biomass. Herein, we report a hard carbon material derived from abundant and abandoned biomass of sorghum stalk through a simple carbonization method. The effects of carbonization temperature on microstructure and electrochemical performance are investigated. The hard carbon carbonized at 1300 °C delivers the best rate capability (172 mAh g−1 at 200 mA g−1) and good cycling performance (245 mAh g−1 after 50 cycles at 20 mA g−1, 96% capacity retention). This contribution provides a green route for transforming sorghum stalk waste into "treasure" of promising low-cost anode material for SIBs.
