In this study, the LiFePO4 cathode was synthesized by the ionic thermal method using the deep eutectic mixture of tetra-Me ammonium chloride and urea. The synthetic conditions were systematically investigated by orthogonal experiments, which indicate that the optimal reaction time, reaction temperature, molar ratio of Li to DES and rotate speed are 96 h, 220 °C, 1:14 and 20 r·min -1, resp. X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) were characterized to investigate the crystalline structure and morphol. of the obtained materials, indicating well-crystallized LiFePO4 with olivine structure. And the phys. properties of LiFePO4 were explored through Fourier transform IR spectroscopy (FTIR), 57Fe Mossbauer absorption spectra and Raman spectra. An initial discharge capacity can reach 151 mAh·g-1 at 0.1C rate for LiFePO4 following by calcining at 600°C under the optimal conditions, and it retains 125.1 mAh·g-1 after 100 cycles. These results demonstrated that the addition of ionic liquids can improve the rate performance, cycle performance and ion diffusion rate of LiFePO4. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Recommanded Product: 75-57-0).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Recommanded Product: 75-57-0
