英文摘要 | Sodium iron hexacyanoferrate (NaFeHCF) containing Fe as the only transition metal element has attained extensive interest for Na-ion batteries due to the low raw material cost and high resource abundance; however, the traditional solution-based synthesis methods, including coprecipitation and hydrothermal reaction, are usually time-consuming and difficult to control the interstitial water and Na content in the lattice, which puts a challenge on the high-efficiency and controllable preparation of NaFeHCF. Herein, we demonstrate a rapid and solvent-free mechanochemical route under the Ar atmosphere to synthesize Na1.59Fe[Fe(CN)6]0.950.051.92H2O cathode, which delivers an initial discharge capacity of 鈭?30 mA h g鈭? at 0.2 C and 118 mA h g鈭? at a high rate of 10 C. Besides, ex situ XRD confirms that NaFeHCF cathode experienced a phase transition from the initial cubic phase to Na-free cubic structure during the first charging process and followed by a reversible phase change between the monoclinic and Na-free cubic structures in the subsequent cycles. More impressively, the optimized NaFeHCF/NaTi2(PO4)3 full cell reveals a decent capacity retention of 80% over 1000 cycles at 1 C, exhibiting a promising prospect in the practical application. Our current work sheds light on the high-efficient scalable production of high-performance NaFeHCF cathodes for Na-ion batteries via mechanochemical approach. 漏 2022 Elsevier Ltd |
