Degradation of Rhombohedral (Y0.25Bi0.75)2O3 Solid Electrolyte

Electrolyte and Solid-Electrolyte Interphase Layer in Lithium-Ion Batteries

The supply and the management of the energy are particularly at the centre of our daily concerns and represent a socio-economic priority. Indeed, while cars use fossil fuel as the main source of energy for over a century, the depletion of the oil reserves and the necessity to reduce the carbon dioxide emissions, stimulate the development of electric vehicles. Therefore, one of the main challeng...

An all solid-state electrochemical electrolyte analyzer.

Ion-selective electrodes have been applied to analysis of blood electrolytes with some success. However, currently available ion-selective electrode systems tend to be elaborate and expensive. We describe a clinical electrolyte analyzer in which inexpensive ion-selective electrodes are used. The elec‘trodes are in the configuration of thin wires and are all solid in construction. They may be di...

Solid Electrolyte Interphases: A Review of Solid Electrolyte Interphases on Lithium Metal Anode (Adv. Sci. 3/2016)

Electrolyte Degradation in Anode Supported Microtubular YSZ-based Solid Oxide Steam Electrolysis Cells at high voltages of operation

Degradation of solid oxide electrolysis cells (SOECs) is probably the biggest concern in the field of high temperature steam electrolysis (HTSE). Anode supported, YSZ-based microtubular solid oxide fuel cells (SOFC) have been tested in fuel cell mode and also at high voltages (up to 2.8V) under electrolysis mode. At high steam conversion rates the cell voltage tends to saturate. Our hypothesis ...

Rhombohedral superhard structure of BC2N

Ab initio evolutionary algorithm was employed to resolve the crystal structure of the observed superhard BC2N. We uncovered two polymorphs with rhombohedral 2 f.u./cell and orthorhombic 2 f.u./cell symmetries, with which the experimental x-ray diffraction pattern is well reproduced. Analysis of the total energy results and the simulated energy-loss near-edge spectroscopy suggests that the rhomb...
