Solid State Synthesis Method

A novel cathode material with Ti-substitution on Ni site, P2-type Na0.67Ni0.25Ti0.08Mn0.67O2 has been synthesized via solid-state synthesis method and characterized electrochemically. Na0.67Ni0.25Ti0.08Mn0.67O2 electrodes have been observed tobe highly reversible at higher voltage ranges. The electrodes have an initial discharge capacity of 125 mAhg-1and can retain around 84% of this capacity (105 mAhg-1) even after 50 cycles at 0.1C when cycled at an uppercut-off voltage of 4.3 V. Na0.67Ni0.25Ti0.08Mn0.67O2 electrodes are believed to suppress the irreversible P2-O2 transformation by diverting the charging reaction through a more reversible P2-OP4transition.

Single phase materials with general formula CdxMeyCr2Se4 (where Me = Mn, Sn) were obtained using solid state synthesis method. Both compounds are ferromagnets with TC =115K (Sn) and 135K (Mn). The values of Curie-Weiss parameter ΘC-W = 135K (Sn) and 145K (Mn) are higher than respective values of TC indicating a presence of competing antiferromagnetic component. The values of lattice parameters are consistent with Sn and Mn replacing Cd. Slight cadmium deficiency has been also observed.

AbstractIn this study, LaxMoyOz powders were synthesized by a cost-effective solid-state synthesis method. Four different heating cycles were designed to investigate the effects of synthesis temperature and holding time on lanthanum molybdate (LMO) formation, phase assemblies, particle size and morphology. X-Ray Diffraction (XRD) and scanning electron microscopy (SEM) studies were performed to observe crystal structure and particle morphology of synthesized powders. The results showed that nearly ninety percent β - La2Mo2O9 (43,3 nm crystal size) phase was obtained at 1000 °C for 6 h holding time. Longer holding times at 1000 °C favor more oxygen-rich compounds which cause recrystallization of various new crystalline phases. The grain size of the synthesized powder was increased from 0,2 µm to 1,5 µm with increasing holding time. In summary, it is possible to manufacture LMO powders rich in β - La2Mo2O9 by one - step solid - state synthesis method. The phase assembles and particle size of LMO powders could also be tailored by optimization of heat treatment cycle.
