  摘要：

  通过对 LiFePO4 粉末进行化学脱硫，然后对 FePO4 进行电化学钠化，制备出了具有橄榄石晶体结构的高性能 NaFePO4 阴极粉末。这种 IL 电解质具有较高的热稳定性（>400 °C）和不燃性，因此是高安全应用的理想选择。研究了 NaTFSI 浓度（0.1-1.0 M）对 25 °C 和 50 °C 下电池性能的影响。在 0.5 M NaTFSI 加入的 IL 电解质中，NaFePO4 在 50 °C 时的最佳容量为 125 mA h g-1（0.05 C 时）；此外，当充放电速率增加到 1 C 时，可保持 65% 的容量。使用 1 M NaTFSI 嵌合型 IL 电解质，在 50 °C 条件下进行 100 次充放电循环后，电池容量损失率为 13%，而在相同条件下使用有机电解质时，电池容量损失率为 38%。

  An effective method for preparing uniform carbon coated nano-sized LiFePO4 particles

  摘要：

  In this paper, nano-sized LiFePO4 particles with a uniform carbon coating were produced using FePO4 as the iron source and PVA gel as the carbon source. Due to the special ability of PVA gel to form films readily, after it was mixed with the FePO4 during the ball-milling process, PVA films were formed readily around FePO4. As shown by the TEM results. the PVA films were successfully transformed into a perfect carbon coating around the LiFePO4 during calcination. The Raman spectrum showed the high quality of the obtained carbon layer, and the LiFePO4/C composites exhibited a high capacity and rate capacity retention at the rates of 0.1 C and 20 C. These results are indicative of the advantages of using PVA gel as a carbon source and its contribution to the excellent electrochemical performance of LiFePO4/C composite nanoparticles.

  phosphates, LiMPO4 (M = Mn, Fe, Co, and Ni), have attracted significant research interest over the past two decades as an important class of lithium ion battery cathode materials. However, almost all of the investigations thus far have focused on the olivine polymorph that exists in the orthorhombic Pnma space group. In this study, a distinct orthorhombic but non-olivine polymorph of LiMPO4, described

  锂过渡金属磷酸盐LiMPO 4（M = Mn，Fe，Co和Ni）作为锂离子电池正极材料的重要一类，在过去的二十年中引起了广泛的研究兴趣。但是，到目前为止，几乎所有的研究都集中在正交晶体Pnma空间群中存在的橄榄石多晶型物上。在这项研究中，已合成出一种由Mcm，Mn，Fe，Co和Ni组成的，由Cmcm空间群对称性描述的LiMPO 4的正交晶但非橄榄石的多晶型物。其中，的LiMnPO 4在CMCM空间组是首次报告。快速微波辅助溶剂热（MW-ST）加热工艺，以四甘醇（TEG）为溶剂，草酸过渡金属盐为前体，有助于这些材料的合成。峰值反应温度和压力分别低于300°C和30 bar，比以前报道的高压方法（千兆帕斯卡）要低几个数量级。X射线衍射（XRD）证实了Cmcm的晶体结构空间群，扫描电子显微照片表明亚微米级的薄片状形态。通过XRD和电感耦合等离子体发射光谱（ICP-OES）对合成工艺条件进行了优化

  significantly altered the electrochemical properties of the olivine cathode: large specific capacity (> 140 mAh/g) and small capacity fading. Although the importance of carbon deposition was confirmed as reported elsewhere, the structural modification effect was also more important than the surface one. The result will contribute to reduce carbon content of LiFePO 4 -based positive electrodes, which is important

  LiFePO 4 基橄榄石化合物是通过通常的陶瓷方法制备的，其中进行了一些修改以提高阴极化合物的导电性。考虑到阴极由电化学活性颗粒和非活性聚合物粘合剂组成，因此采用了两种不同的方法。一是与粒子间传导性的提高有关，二是活性粒子本身导电性的增强。前者是在样品制备过程中通过有机添加剂（芘）的热分解获得的，并用拉曼光谱研究沉淀的碳。通过用 Mn 2+ 部分取代 Fe 2+ 来改善橄榄石的整体电导率，其中空穴被并入价带。这些修改显着改变了橄榄石正极的电化学性能：大比容量（> 140 mAh/g）和小容量衰减。尽管如别处报道的那样证实了碳沉积的重要性，但结构改性效果也比表面效果更重要。结果将有助于降低基于LiFePO 4 的正极的碳含量，这对其实际应用很重要。

  Electrochemical insertion of lithium into four Li3Fe2(XO4)3polymorphs (X=P or As) with 3-D framework structures was carried out in “Li/LiClO4(PC:DME)/cathode” coin cells. Approximately 2 Li per formula unit could be reversibly inserted into the three different structures, which corresponds to the reduction of all Fe3+to Fe2+between 2.5 and 3.5 V vs lithium.

Orthorhombic LiMnO 2 , layered LiMn 0.8 Cr 0.2 O 2 , and spinel LiMn 2 O 4 containing Mn 3+ exhibit much higher amounts of manganese dissolution irrespective of the structure compared
