“…During the past decade, enormous efforts have been made to peruse different kinds of electrode materials for SIBs [5][6][7][8][9][10][11]. Specifically, for the cathodes, transition metal oxides [12][13][14][15][16][17][18], phosphates [19][20][21][22][23][24][25][26][27][28], and ferrocyanides [29,30], have demonstrated decent electrochemical properties. From the structural and economic aspects, Fe-based polyanions should be a favorable choice for electrode materials, owing to the combination of the cost-effective and environmental-friendly of Fe element, with the robust and stable structure of polyanion frameworks essential for prolonged cycling and safety issues [31,32].…”

Iron-based electrodes have attracted great attention for sodium storage because of the distinct cost effectiveness. However, exploring suitable iron-based electrodes with high power density and long duration remains a big challenge. Herein, a spray-drying strategy is adopted to construct graphene-coated Na 2.4 Fe 1.8 (SO 4 ) 3 nanograins in a 3D graphene microsphere network. The unique structural and compositional advantages endow these electrodes to exhibit outstanding electrochemical properties with remarkable rate performance and long cycle life. Mechanism analyses further explain the outstanding electrochemical properties from the structural aspect.

“…3e-h Figure 4a shows the initial three cycles CV curves of the as-prepared Co 2 B 2 O 5 material at 0.2 mVÁs -1 . During the first reduction process, there are two obvious peaks positioned at 0.01 and 0.30 V, and this can be assigned to structural transformation and the formation of SEI layer [29,37]. In the oxidation process, the peak is positioned at 1.8 V. In the following cycles, the reduction peak is located at a relatively high potential of 0.80 V, and in oxidation process, a weak peak is located at 1.90 V. The first three galvanostatic charge/discharge curves of Co 2 B 2 O 5 are displayed in Fig.…”

In this work, a flake-structured Co 2 B 2 O 5 material was obtained by a simple sol-gel method and researched for use in sodium ion batteries firstly. When serving as anode material for sodium ion batteries, it exhibits the high initial reversible capacity of 466 mAhÁg -1 at a current density of 100 mAÁg -1 . Through the recombination of carbon nanotubes (CNTs), the composite Co 2 B 2 O 5 /CNTs delivers the initial reversible capacity of 464 mAhÁg -1 , and 324 mAhÁg -1 is obtained after 60 cycles under the current density of 100 mAÁg -1 . When under the current density of 1000 mAÁg -1 , a capacity of 236 mAhÁg -1 is obtained for Co 2 B 2 O 5 /CNTs while 160 mAhÁg -1 for Co 2 B 2 O 5 . Moreover, the sodium storage behavior of Co 2 B 2 O 5 is identified by kinetic analysis. The higher Na ? capacitive contribution of Co 2 B 2 O 5 /CNTs could account for the enhanced rate performance. The results indicate that Co 2 B 2 O 5 is a promising anode material for sodium ion batteries.

The anode materials for sodium‐ion batteries (SIBs) such as soft carbon, hard carbon, or alloys suffer from low specific capacity, poor rate capability, and high cost. Various transition metal oxides materials possess high specific capacity and suitable working potential, however, huge volume change and unstable electrode/electrolyte interfaces limit their practical applications. Herein, an ultrathin carbon‐coated iron‐based borate, (Fe3BO5), as an anode material for SIBs is reported. The carbon coated Fe3BO5 composite as an anode material possesses a reversible specific capacity of 548 mAh g−1 with a high initial coulombic efficiency of 72.6% at a current density of 50 mA g−1, and maintains a capacity retention ratio of 99% after 1000 cycles at 2000 mA g−1. Moreover, this anode can work well over a wide temperature range (‐40–60 °C). Furthermore, a sodium‐ion full cell using this anode coupling with iron‐based cathode (Na3Fe2(PO4)2(P2O7)@rGO) cathode is fabricated, which exhibits a wide operating temperature range from −40 to 60 °C with a maximum energy density of 175 Wh Kg−1 and a maximum power density of 1680 W Kg−1. Most importantly, this full‐cell configuration is low‐cost due to its inexpensive iron based raw material for both anode and cathode.
