Abstract

This research work focuses on the synthesis and performance evaluation of NaFe Cr (SO) ( = 0, 0.8 and 1.0) cathode materials in sodium ion batteries (SIBs). The novel materials having a primary particle size of around 100-200 nm were synthesized through a sol-gel process by reacting stoichiometric amounts of the precursor materials. The structural analysis confirms the formation of crystalline, phase pure materials that adopt a monoclinic crystal structure. Thermal analysis indicates the superior thermal stability of NaFe0Cr(SO) when compared to NaFe(SO) and NaCr(SO). Galvanostatic charge/discharge analysis indicates that the intercalation/de-intercalation of a sodium ion (Na) into/from NaFe(SO) ensues at about 3.2 V due to the Fe/Fe active redox couple. Moreover, XRD analysis confirms that the insertion/de-insertion of sodium into/from the host structure during charging/discharging is accompanied by a reversible single-phase reaction rather than a biphasic reaction. A similar sodium intercalation/de-intercalation mechanism has been noticed in NaFeCr(SO)which has not been reported earlier. The galvanostatic measurements and X-ray photoelectron spectroscopy (XPS) analysis confirm that the Cr/Cr redox couple is inactive in NaFe Cr (SO) ( = 0, 0.8) and thus does not contribute to capacity augmentation. However, suitable carbon coating may lead to activation of the Cr/Cr redox couple in these inactive materials.

摘要

本研究工作聚焦于钠离子电池（SIBs）中NaFeₓCr₁₋ₓ(SO₄)₂（x = 0、0.8和1.0）正极材料的合成与性能评估。通过使化学计量的前驱体材料反应，采用溶胶 - 凝胶法合成了初级粒径约为100 - 200 nm的新型材料。结构分析证实形成了具有单斜晶体结构的结晶、相纯材料。热分析表明，与NaFe(SO₄)₂和NaCr(SO₄)₂相比，NaFe₀Cr₁(SO₄)₂具有优异的热稳定性。恒电流充放电分析表明，由于Fe³⁺/Fe²⁺活性氧化还原对，钠离子（Na⁺）在约3.2 V时嵌入/脱嵌NaFe(SO₄)₂。此外，XRD分析证实，充电/放电过程中钠离子在主体结构中的嵌入/脱嵌伴随着可逆的单相反应而非双相反应。在NaFeₓCr₁₋ₓ(SO₄)₂中也观察到了类似的钠离子嵌入/脱嵌机制，这在之前尚未见报道。恒电流测量和X射线光电子能谱（XPS）分析证实，在NaFeₓCr₁₋ₓ(SO₄)₂（x = 0、0.8）中Cr³⁺/Cr²⁺氧化还原对不活跃，因此对容量增加没有贡献。然而，合适的碳涂层可能会使这些不活跃材料中的Cr³⁺/Cr²⁺氧化还原对活化。
