Jatinkumar Rana,Richard Kloepsch,Jie Li,Tobias Scherb,Gerhard Schumacher,Martin Winter,John Banhart,John Banhart +7 more
TL;DR: In this paper, structural changes in a 0.5Li2MnO3·0.5 LiCoO2 cathode material were investigated by X-ray absorption spectroscopy.
Journal ArticleDOI
Manganese Dioxide Graphite Composite Electrodes Formed via a Low Temperature Method: Detection of Hydrogen Peroxide, Ascorbic Acid and Nitrite
TL;DR: In this article, a manganese dioxide modified carbon powder was prepared via a wet impregnation method from the solution of permanganate salt, which was used for fabrication of composite electrodes and their potential application in the field of electroanalysis investigated.

Thermodynamics and kinetics of phase transformation in intercalation battery electrodes – phenomenological modeling
Wei Lai,Francesco Ciucci +1 more
TL;DR: In this paper, a mean-field lattice-gas thermodynamic model and a generalized Poisson-Nernst-Planck equation set based on linear irreversible thermodynamics are investigated for phase transformation in intercalation battery electrodes.

Designed hierarchical MnO2 microspheres assembled from nanofilms for removal of heavy metal ions
TL;DR: Hierarchical MnO2 microspheres assembled from nanofilms are fabricated through an environmental route and subsequent drying under vacuum as discussed by the authors, which can allow for higher exposure of adsorption sites to adsorbate molecules than a solid one, and thus results in the high removal efficiency of heavy metal ions.

LixCoO2 (0<x<-1): A new cathode material for batteries of high energy density
TL;DR: In this paper, a new system LixCoO2 (0 Li x CoO 2 Li ) is proposed, which shows low overvoltages and good reversibility for current densities up to 4 mA cm−2 over a large range of x.
Journal ArticleDOI
Zero‐Strain Insertion Material of Li [ Li1 / 3Ti5 / 3 ] O 4 for Rechargeable Lithium Cells
TL;DR: In this paper, a defect spinel-framework structure was examined in nonaqueous lithium cells and it was shown that the lattice dimension did not change during the reaction since the reaction consists of lithium ion and electron insertion into/extraction from the solid matrix without a noticeable change in lattice dimensions.
Journal ArticleDOI
Lithium insertion into manganese spinels
TL;DR: In this article, Li has been inserted chemically and electrochemically into Mn3O4 and Li[Mn2]O4 at room temperature from X-ray diffraction.

Electrochemical and In Situ X‐Ray Diffraction Studies of Lithium Intercalation in Li x CoO2
Jan N. Reimers,J. R. Dahn +1 more
TL;DR: In this article, high precision voltage measurements and in situ x-ray diffraction indicate a sequence of three distinct phase transitions as varies from 1 to 0.4, two of which are situated slightly above and below and are caused by an order/disorder transition of the lithium ions.

Improved capacity retention in rechargeable 4 V lithium/lithium- manganese oxide (spinel) cells
TL;DR: In this article, the authors improved the rechargeable capacity of 4 V LixMn2O4 spinel cathodes by modifying the composition of the spinel electrode, achieving a capacity in excess of 100 mAh/g in flooded-electrolyte lithium cells.
