  stages of electrode preparation as shown through the synthesis of LiFeSO 4 F and its implementation into an electrode. The importance of having Fe 3+ -free hydrated precursors to routinely obtain pure LiFeSO 4 F samples is shown together with the need to optimize ballmilling conditions to preserve Fe 3+ -free LiFeSO 4 F composites. Samples prepared via this low temperature solid-state process show battery

  离子热合成最近已被用于制备氟硫酸盐 (LiFeSO 4 F)，该氟硫酸盐 (LiFeSO 4 F) 能够以 3.6 V 与 Li 的电压可逆地嵌入 Li，使该材料成为 HEV 和电动汽车应用中 LiFePO 4 的有力竞争者。尽管氟硫酸盐由低成本和丰富的原料制成，但由于使用离子液体作为合成介质，它们的合成成本很高。在此，我们报告了一种固态过程，通过该过程可以在不使用离子液体的情况下合成 LiFeSO 4 F，但代价是更长的反应时间和弱污染的样品。此外，我们展示了穆斯堡尔光谱在优化电极制备的各个阶段方面的强大功能，如通过 LiFeSO 4 F 的合成及其在电极中的实施所示。显示了使用不含 Fe 3+ 的水合前体对常规获得纯 LiFeSO 4 F 样品的重要性以及优化球磨条件以保护不含 Fe 3+ 的 LiFeSO 4 F 复合材料的需要。通过这种低温固态工艺制备的样品显示出接近使用离子液体作

  Tavorite LiFeSO4F cathode material is prepared by the solvothermal method. The thermal stability of delithiated LixFeSO4F is characterized by X-ray diffraction, differential scanning calorimetry and thermogravimetric analysis. It shows that the side reactions between the cathode material and the electrolyte are moderate, which involves the decomposition of LixFeSO4F forming Fe2(SO4)3 and Li2SO4 phases

  We have recently reported a promising 3.6 V metal fluorosulphate (LiFeSO4F) electrode, capable of high capacity, rate capability, and cycling stability. In the current work, we extend the fluorosulphate chemistry from lithium to sodium-based systems. In this venture, we have reported the synthesis and crystal structure of NaMSO4F candidates for the first time. As opposed to the triclinic-based LiMSO4F phases, the NaMSO4F phases adopt a monoclinic structure. We further report the degree and possibility of forming Na(Fe1-xMx)SO4F and (Na1-xLix)MSO4F (M = Fe, Co, Ni) solid-solution phases for the first time. Relying on the underlying topochemical reaction, we have successfully synthesized the NaMSO4F, Na(Fe1-xMx)SO4F, and (Na1-xLix)MSO4F products at a low temperature of 300 degrees C using both ionothermal and solid-state syntheses. The crystal structure, thermal stability, ionic conductivity, and reactivity of these new phases toward Li and Na have been investigated. Among them, NaFeSO4F is the only one to present some redox activity (Fe2+/Fe3+) toward Li at 3.6 V. Additionally, this phase shows a pressed-pellet ionic conductivity of 10(-7) S.cm(-1). These findings further illustrate the richness of the fluorosulphate crystal chemistry, which has just been recently unveiled.
