“…Both values are higher than that reported in previous work. 20 The result is attributed to that the snowflakeand flower-like particles have less contact points than the spherical particles in the same unit distance. Therefore, the conductivity of snowflake-like Fe-Ni and flower-like alloy is higher than that of Fe-Ni spherical particles.…”

Snowflake-like Fe-Ni alloy has been synthesised via a facile hydrothermal approach without any soft and hard template. The structure of the snowflake-like Fe-Ni alloy was characterised by means of scanning electron microscopy (SEM), X-ray diffraction and energy dispersive X-ray spectroscopy. The dendrite trunk lengths of the snowflake-like Fe-Ni alloy were about 2?5-7?0 mm, and those of the branch trunk ranged from 250?0 to 650?0 nm. Furthermore, it was found that the formation and morphology of Fe-Ni alloy strongly depended on the reaction time. Moreover, the magnetic and electrical properties of Fe-Ni alloy with various morphologies were compared. Moreover, the result showed that the snowflake-like Fe-Ni alloy indicated enhancement of their ferromagnetic and electrical properties, which was attributed to their anisotropic shape.

“…We use the following material properties of lead bismuth eutectic (LBE) at 160 The electrical conductivity of the vessel is assumed to be σ = 1.37 • 10 6 S/m and of the wires and copper plate σ = 58.1 • 10 7 S/m. The electrical conductivity of the Fe-Ni foam is not easy to determine [68,69], especially because it is not sure if the liquid metal enteres the pores. We do not model the porosity and use an electric conductivity of σ = 1.37 • 10 6 S/m without further justification.…”

Liquid metal batteries (LMBs) were recently proposed as cheap large scale energy storage. Such devices are urgently required for balancing highly fluctuating renewable energy sources. During discharge, intermetallic phases tend to form in the cathode of LMBs. These do not only limit the up-scalability, but also the efficiency of the cells. Generating a mild fluid flow in the fully liquid cell will smoothen concentration gradients and minimise the formation of intermetallics.In this context we study electro-vortex flow numerically. We simulate a recent LMB related experiment and discuss how the feeding lines to the cell can be optimised to enhance mass transfer. The Lorentz forces have to overcome the stable thermal stratification in the cathode of the cell; we show that thermal effects may reduce electro-vortex flow velocities considerable. Finally, we study the influence of the Earth magnetic field on the flow.
