Li-Rich Li1+xMn2–xO4 Spinel Electrode Materials: An Operando Neutron Diffraction Study during Li+ Extraction/Insertion
Matteo Bianchini,Emmanuelle Suard,Laurence Croguennec,Christian Masquelier,Christian Masquelier +4 more
TL;DR: In this article, the deintercalation process occurring in manganese spinels of general formula Li 1+xMn2−xO4 was studied and three samples with increasing Li/Mn ratio were synthesized and measured on the D20 high-flux powder diffractometer at ILL.
Journal ArticleDOI
The effect of ZnO coating on LiMn2O4 cycle life in high temperature for lithium secondary batteries
TL;DR: In this article, the surface of the spinel LiMn 2 O 4 was modified with zinc oxide by a chemical process to improve its electrochemical performance at high temperatures, and the discharge capacity of the ZnO-coated spinel was shown only 3% loss of the initial capacity over 60 cycles.
Journal ArticleDOI
Spectroelectrochemical Investigations of Cation-Insertion Reactions at Sol−Gel-Derived Nanostructured, Mesoporous Thin Films of Manganese Oxide†
TL;DR: In this article, the electrochromic properties of manganese oxide, a mixed electron−cation conductor, provide an independent measure of the electronic state of the oxide during the electrochemically driven cation-insertion process.
Journal ArticleDOI
Applications of nano-porous graphene materials – critical review on performance and challenges
Albert Guirguis,James W. Maina,Xiwang Zhang,Luke C. Henderson,Lingxue Kong,Ho Kyong Shon,Ludovic F. Dumée +6 more
TL;DR: In this paper, the authors present and discuss the very recent developments in the synthesis of perforated graphene-based materials and correlate the morphology and other properties of such 2D nano-porous materials to their performance in applications such as separation, sensing and energy.
Journal ArticleDOI
The role of particle size on the electrochemical properties at 25 and at 55 °C of the LiCr0.2Ni0.4Mn1.4O4 spinel as 5V-cathode materials for lithium-ion batteries
TL;DR: The role of the particle size on the electrochemical properties at 25 and at 55°C of the LiCr 02 Ni 04 Mn 14 O 4 spinel synthesized by combustion method has been determined.

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.
Journal ArticleDOI
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.
