Lithium deintercalation in LiFePO4 nanoparticles via a domino-cascade model

Claude Delmas, +4 more
- 20 Jul 2008 - 
TL;DR: A characterization of electrochemically deintercalated nanomaterials by X-ray diffraction and electron microscopy that shows the coexistence of fully intercalated and fully deIntercalated individual particles indicates that the growth reaction is considerably faster than its nucleation.
Journal ArticleDOI

Reversible Oxygen Participation to the Redox Processes Revealed for Li1.20Mn0.54Co0.13Ni0.13O2

Hideyuki Koga, +9 more
- 01 Jan 2013 - 
TL;DR: In this paper, the authors investigated the role of oxygen and manganese in the redox process in charge and showed that oxygen is significantly more involved in the reduction process than O2.
Journal ArticleDOI

Different oxygen redox participation for bulk and surface: A possible global explanation for the cycling mechanism of Li1.20Mn0.54Co0.13Ni0.13O2

Hideyuki Koga, +6 more
- 15 Aug 2013 - 
TL;DR: In this paper, an X-ray diffraction analysis reveals that irreversible structural reorganization of this lithium and manganese-rich layered oxide occurs during the 1st charge and continues during a few cycles.
Journal ArticleDOI

Mechanisms Associated with the “Plateau” Observed at High Voltage for the Overlithiated Li1.12(Ni0.425Mn0.425Co0.15)0.88O2 System

Nicolas Tran, +6 more
- 15 Jul 2008 - 
TL;DR: In this article, the structural modifications occurring during the first cycle and especially during the irreversible “plateau” observed in charge at 4.5 V vs Li+/Li.
Journal ArticleDOI

Reinvestigation of Li2MnO3 Structure: Electron Diffraction and High Resolution TEM

Adrien Boulineau, +7 more
- 27 Aug 2009 - 
TL;DR: The structure of Li2MnO3 was investigated by the means of X-ray and electron diffraction as well as high-resolution transmission electron microscopy experiments as discussed by the authors.
