An infrared absorption study of lithium in silicon
Lithium, lithium oxide, and the group V elements, phosphorus, arsenic, antimony, and bismuth, when present in silicon as impurities, act as "shallow" donors (2, 7, 11). These donors have electrons which are bound so loosely that they may be thermally excited into the conduction band at less than …

Evolution of molecular structure during the sol-gel processing of lithium niobate and the development of microstructure in alkoxide-derived thin layers
Lithium niobate powders and thin-layers were prepared by sol-gel processing. Lithium niobium ethoxide and lithium niobium methoxyethoxide bimetallic alkoxides were used for both gel and thin-layer formation. Advantages of sol-gel processing were demonstrated by synthesis of …

Material Interactions with Molten LiCl-Li2O-Li
The electrolytic reduction of oxide nuclear fuel in a molten lithium chloride electrolyte containing 1-2wt% lithium oxide is a fuel cycle process that has been established on an engineering scale. The electrochemical window of lithium oxide must be exceeded in order to conduct this process at an …

Planar copper containing anode-supported solid oxide fuel cells
… anode supported Intermediate Temperature Solid Oxide Fuel Cells (IT-SOFCs) were produced by single step cosintering. The anode and the electrolyte were realized through water-based tape casting, the cathode being added by screen printing. A 5 mol% of Lithium oxide addition allowed reducing the …

Single-component Li₂O solid electrolyte interphase on lithium : probing transport properties in battery environments
Lithium (Li) anodes suffer numerous challenges arising from the chemically inhomogeneous nature of the native solid electrolyte interphase (SEI), which impedes smooth Li plating and leads to dendrite growth. In spite of much attention paid to engineering Li interfaces of late, there is still …

Chemistry, Transport and Function of Ionic Phases in the Solid Electrolyte Interphase on Lithium Metal Anodes
Lithium (Li) metal anodes in liquid electrolytes suffer low Coulombic efficiency (< 99.9%) arising from the chemically inhomogeneous nature of the native solid electrolyte interphase (SEI), which impedes smooth Li plating and leads to excessive electrolyte consumption. Despite much attention paid …

Electrochemistry of systems containing aluminum phosphate dissolved in fused borate and phosphate mixtures
… most frequently used. It is known that aluminum oxide is peptized by aluminum chloride. Severe corrosion is expected on articles electroplated in the presence of aluminum chloride. In the present investigation, the use of aluminum halides was avoided. Aluminum phosphate was employed in the system …
