Maximum Electrical Conductivity of Associated Lithium Salts in Solvents for Lithium-Air Batteries
(American Chemical Society, 2019-05)
The choice of optimal electrolytes is crucial for improving the electrochemical performance of a lithium air battery because it determines the morphology of the discharge products in the cathode and the conductivity of the ...
Comment on “Out-of-Cell Oxygen Diffusivity Evaluation in Lithium–Air Batteries” by He et al.
(Wiley, 2017-02)
In a recent paper, He et al. (ChemElectroChem 2014, 1, 2052–2057) described a methodology for measuring out-of-cell oxygen diffusivity in lithium–air battery (LAB) cathodes, combining an electrochemical device with a ...
Oxidation state of lithium species. XPS binding energies of lithium 1s electrons in salts, the metal and intercalated in molybdenum sulfide
(1996)
The binding energies of Li (1s) electron in a series of lithium salts, the metal, and lithium intercalated in molybdenum sulfide measured with respect to Au (4f7/2) agree with both the expected ionic character and oxidation ...
New Evidence of LiO2 Dismutation in Lithium–Air Battery Cathodes
(Wiley VCH Verlag, 2016-10)
The dismutation of electrochemically generated soluble lithium superoxide with the formation of a lithium peroxide deposit on Au has been studied by addition of lithium ions and following the mass uptake detected by the ...
Lithium recovery from brines: A vital raw material for green energies with a potential environmental impact in its mining and processing
(Elsevier, 2018-10)
The electrification of our world is driving a strong increase in demand for lithium. Energy storage is paramount in electric and hybrid vehicles, in green but intermittent energy sources, and in smart grids in general. ...
The kinetics of oxygen electroreduction: a long way from iron rust to lithium-air batteries
(Wiley VCH Verlag, 2014-03)
In this communication, we review the details of the oxygen electroreduction reaction on rust layers, passive iron and well defined iron oxides as cathodes for the reaction. In particular, we highlight the important ...
Ionic Transport and Speciation of Lithium Salts in Glymes: Experimental and Theoretical Results for Electrolytes of Interest for Lithium-Air Batteries
(American Chemical Society, 2018-09)
Glycol ethers, or glymes, have been recognized as good candidates as solvents for lithium-air batteries because they exhibit relatively good stability in the presence of superoxide radicals. Diglyme (bis(2-methoxy-ethyl)ether), ...
A rotating ring disk electrode study of the oxygen reduction reaction in lithium containing non aqueous electrolyte
(Elsevier, 2013-03-16)
We show the effect of a very small addition of LiClO4 to tetraethyl ammonium perchlorate (TEAP) in acetonitrile on the electro-reduction of molecular oxygen (ORR) at a rotating ring (Pt) glassy carbon (GC) disk electrode. ...
Surface studies of lithium-oxygen redox reactions over HOPG
(Elsevier Science, 2016-04)
The O2/Li2O2 electrode reaction has been studied on low surface area HOPG electrodes in 0.1 M LiPF6 in dimethyl sulfoxide (DMSO) electrolyte. Studies were performed using electrochemical cells coupled to a XPS spectrometer ...
Aging effect of atmospheric air on lithium disilicate ceramic after nonthermal plasma treatment
(2016-06-01)
Statement of problem Nonthermal plasma (NTP) treatment is an alternative technique for promoting the adhesion of resin cement to lithium disilicate ceramic. However, no study has evaluated whether the surface modifications ...
