Thermodynamic Stability of Low- and High-Index Spinel LiMn2O4 Surface Terminations
TL;DR: Thermodynamic analysis is extended to identify stable structures for certain high-index surfaces, including (311), (331), (511), and (531), which constitute simple models for steps or defects that may be present on real LMO particles, in agreement with the experimental observations of LMO particle shapes.
Journal ArticleDOI
Influence of laser pulse duration on the electrochemical performance of laser structured LiFePO 4 composite electrodes
TL;DR: In this paper, three dimensional (3D) architectures were generated in composite cathode layers to overcome the reduced rate performance, and the capacity retention and the cycle stability were significantly improved, especially for high charging/discharging currents.
Journal ArticleDOI
Structural study of Li2MnO3 by electron microscopy
TL;DR: In this article, a high-purity Li2MnO3 powder was annealed at 950°C for 3 days to obtain predominantly defect-free grains which average size was 3.0 − 1.5 µm.
Journal ArticleDOI
Enhanced high rate performance of LiMn2O4 spinel nanoparticles synthesized by a hard-template route
Jordi Cabana,Teresa Valdés-Solís,Maria Rosa Palacín,Judith Oró-Solé,Antonio B. Fuertes,Gregorio Marbán,Amparo Fuertes +6 more
TL;DR: In this paper, a nanosized LiMn 2 O 4 spinel was prepared by a novel route using a porous silica gel as a sacrificial hard template, which was found to be made up of 8-20nm nanoparticles with a mean crystallite size of 15-nm.

TL;DR: In this article, high-resolution X-ray diffraction-computed tomography is used to spatially and temporally quantify lithium ion heterogeneities within and between particles throughout both fresh and degraded LixMn2O4 electrodes.

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.
