Effect of nanocrystallinity on the electrochemical performance of LiMn2O4 cathode
TL;DR: In this article, the authors have synthesized nanocrystalline LiMn2O4 of different grain sizes, for application to Li ion rechargeable batteries for high-energy ball milled for 8 and 16h, respectively.
Journal ArticleDOI
Improvement in stability of LiMn2O4 thin-film electrodes by oxygen-plasma irradiation to precursor gel
TL;DR: LiMn2O4 thin-film electrodes were prepared by the sol-gel method combined with oxygen-plasma irradiation as discussed by the authors, and they were fired at 723 or 973 K.

Brittle fracture to recoverable plasticity: polytypism-dependent nanomechanics in todorokite-like nanobelts
Ruhul Amin Shikder,M. Maksud,Gokul Vasudevamurthy,Bryan W. Byles,David A. Cullen,Karren L. More,Ekaterina Pomerantseva,Arunkumar Subramanian +7 more
TL;DR: In this paper, an atomic force microscopy (AFM) based nanomechanics experiments involving polytypic todorokite-like manganese dioxide nanobelts reveal varied performance regimes such as brittle fracture, near-brittle fracture, and plastic recovery within the same material system.

Cycling behavior of the oxysulfide LiAl0.18Mn1.82O3.97S0.03 cathode materials at elevated temperature
TL;DR: In this article, a new sulfur-doped spinel material, LiAl0.18Mn1.97S0.03 was synthesized by a sol-gel method and the structural change of the oxysulfide spinel before and after cycling at elevated temperature was studied by charge discharge measurements and X-ray diffraction.

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.
