A molten carbonate fuel cell (MCFC) is an electro-chemical energy conversion technology that runs on natural gas and employs a molten salt electrolyte. In order to keep the electrolyte in this state, the cell must be kept at a temperature above 500◦C, eliminating the need for precious metals as the catalyst. There has been only a limited amount of research on modelling the transport processes i...

Electrodeposition of Si films from a Si-containing electrolyte is a cost-effective approach for the manufacturing of solar cells. Proposals relying on fluoride-based molten salts have suffered from low product quality due to difficulties in impurity control. Here we demonstrate the successful electrodeposition of high-quality Si films from a CaCl2 -based molten salt. Soluble SiIV -O anions gene...

The formal standard redox potentials of samarium (III)/(II) (EZmi+/ Smi+) and europium (III)/(II) (•£,£u3+/eu2+ ) *n molten alkali metal chlorides were measured potentiometrically against a reference chlorine electrode. The Gibbs energy changes and equilibrium constants for the reaction LnCl2(D + V2 Cl2(g) LnCl3(I) were calculated for the salt systems studied. The effect of the cationic composi...

The synthesis of single-crystalline hollandite-type manganese oxides Na2-xMn8O16 nanorods by a simple molten salt method is reported for the first time. The nanorods were characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and a superconducting quantum interference device magnetometer. The magnetic measurements indicated that the nanorods s...

We present a microfield approach for studying the dependence of the orientational polarization of the water in aqueous electrolyte solutions upon the salt concentration and temperature. The model takes into account the orientation of the solvent dipoles due to the electric field created by ions, and the effect of thermal fluctuations. The model predicts a dielectric functional dependence of the...

The extended corresponding states principle has been applied on the prediction of the surface tension of pure molten alkali halides. The model uses liquid density and vapour pressure data of the salts of interest and of the reference salt, chosen to be NaCl, as the input for the calculation of temperature-dependent equivalent substance reducing ratios (ESRR). The model here described was alread...

A secondary battery (accumulator) employing molten metals or metal alloys as active masses at both electrodes and a salt electrolyte in between is called an all-liquid-metal accumulator (LMB). Separation of the liquid based on segregation caused by different densities immiscibility materials characteristic feature. High coulometric storage capabilities molten-metal combined with relatively low ...

Molten salts have been used in solar thermal energy storage due to their high density, low cost and excellent chemical stability. However, application is limited by “bad days” such as cloudy days winter because the weak concentrated radiation cannot melt salt. The current study indicates that through mixing pure salts, melting point of molten salt can be decreased significantly while latent hea...
