Spinel LiMn2O4 were prepared by a molten salt combustion method at 600°C. The phase composition of the products was investigated by X-ray diffraction (XRD), and the electrochemical performance was tested by a coin-type self battery. XRD results presented that the purity and the crystallinity of the products increased with extending calcining time. Single phase LiMn2O4 could be prepared at 600°C for 6 and 12h. The ratio of lithium/manganese also affected the phase compositions of the products. The purity and crystallinity of the product with the molar ratio of Li/Mn=1.1/2 were higher than these of the product with the molar ratio of Li/Mn=1.05/2. The performance tests indicated that the electrochemical performance of the product prepared at 600°C for 6h is the best. The initial discharge capacity was 112.8mAh/g, and after 20 cycles, the capacity retention is 81.8%. The product with Li/Mn=1.1/2 had better electrochemical performance than the product with Li/Mn=1.05/2.

Electrometric Titration

Electrometric titrations have been carried out in molten salt media. An equimolar KNO 3 + NaNO 3 melt was used as solvent, and the following systems were investigated: AgCl, AgBr, AgI, AgCN, Ag(CN) - 2 and Ag 2 CrO 4 . The effect of temperature on the solubility was also studied and heats, free energies and entropies of solution in the melt solvent have been calculated. The process of solution in an ionic melt solvent is discussed. It is suggested that the simple Born theory of solvation is more applicable to a solution in a melt than in an aqueous medium.

Computational fluid dynamics is used to study the effect of temperature on flow structure and disk friction loss for different working fluids in a high temperature molten salt pump, which is used for concentrating solar power, the velocity profile and pressure distribution in the first stage of the pump model and the effect of the fluid property on the ring leakage, disk friction loss as well as the shear stress distribution on shroud are analyzed for the pure water and the molten salt with temperature 300?C and 565?C respectively. The main findings can be concluded as: the working fluids have little effect on pump performance and internal velocity distribution whereas the pressure of the flow field would increase with the fluid density, with the increase of the fluid viscosity, the shear stress inside the ring also increases and the total leakage can be eliminated evidently, the increase of the fluid density and viscosity show the significant responsibility for the disk friction loss, in which the fluid viscosity also increases the disk friction loss, and the viscosity is one of the most influential factors for the shroud shear stress and it can be observed that the shear stress on front shroud is higher than that on the rear shroud. It is believed that the present work can deep the understandings of the fluid structures inside the molten salt pump, which can provide some guidelines to improve the pump performance and optimize the pump structure.
