Lithium manganese oxides for rechargeable lithium batteries

Journal of Power Sources, 1997
Abstract Lithium manganese spinel compounds HT-LiMn 2 O 4 (HT means high temperature) synthesized at > 700 °C have high capacity in the 4 V range (Li x Mn 2 O 4 , x ⩽ 1), However, lithium manganese oxides LT-LiMn 2 O 4 (LT means low temperature) synthesized at temperatures lower than 400 °C, resemble to the spinel structure and tend to have a ...

Lithium Peroxide Surfaces Are Metallic, While Lithium Oxide Surfaces Are Not

Journal of the American Chemical Society, 2011
The thermodynamic stability and electronic structure of 40 surfaces of lithium peroxide (Li(2)O(2)) and lithium oxide (Li(2)O) were characterized using first-principles calculations. As these compounds constitute potential discharge products in Li-oxygen batteries, their surface properties are expected to play a key role in understanding ...

Structural Requirements in Lithium Cobalt Oxides for the Catalytic Oxidation of Water

Angewandte Chemie, 2012
The development of water oxidation catalysts (WOCs) to replace costly noble metals in commercial electrolyzers and solar fuel cells is an unmet need that is preventing the global development of hydrogen fuel technologies. Two of the main challenges in realizing catalytic water splitting are lowering the substantial overpotential that is required to ...

Conductivity of zirconium oxide alloyed with lithium oxide

Glass and Ceramics, 2008
The solid-phase method is used to synthesize polycrystalline samples of zirconium dioxide stabilized with 10% Y2O3 (or content) and up to 3% Li2O. It is found that the conductivity of the samples increases substantially when Li2O is added and reaches its maximum value at 1.7% Li2O. The conduction activation energy decreases from 0.85 eV in samples with

Defect energies for magnesium oxide and lithium oxide

Journal of the Chemical Society, Faraday Transactions, 1990
A new crystal potential has been developed for magnesium oxide. This is based on electron-gas calculations of the interaction energy for like and unlike pairs of ions, in the presence of a model crystal field. The calculated potentials are checked by calculating perfect lattice properties: cohesive energy, elastic constants, dielectric constants and ...

The production of lithium oxide by electron irradiation of lithium fluoride

Journal of Materials Science, 1970
Observations of electron damage occurring in LiF single crystals within an electron microscope are recorded. A number of irradiation-induced defects, similar to those reported by other workers were observed, but a new feature is the identification, by electron diffraction, of Li2O distributed in precipitates and as a dispersed phase.

Reduction of uranium oxides with lithium in a lithium chloride melt

Radiochemistry, 2009
A series of experiments were performed on reduction of uranium oxides to metal with lithium in a LiCl melt, with the aim to develop a process for thermal reactor SNF management. Experiments were performed on an enlarged scale on an installation with the uranium amount charged in one portion of up to 5 kg.

Phase Relationship and Lithium Deintercalation in Lithium Nickel Oxides

Journal of Solid State Chemistry, 1994
Abstract The phase relationship between LiNiO2 and its related compounds was examined by X-ray diffraction, neutron diffraction, DTA-TG, and electrical, magnetic, and electrochemical measurements. Decomposition of LiNiO2 proceeded at higher temperatures to Li1-xNi1+xO2 with the partially disordered α-NaFeO2 structure and LixNi1-xO with the fully ...

THE VAPOR PRESSURE OF LITHIUM IN THE REDUCTION OF LITHIUM OXIDE BY SILICON

Canadian Journal of Chemistry, 1958
The vapor pressure of lithium over the system lithium oxide – calcium oxide – silicon has been measured using the gas entrainment method at temperatures between 970 °C. and 1025 °C. The experimental results are summarized in the form [Formula: see text] where P is in atmospheres and T in °A. The reaction, as usually written,[Formula: see text]does not
