Closing the gap between theory and experiment for lithium manganese oxide spinels using a high-dimensional neural network potential
Marco Eckhoff,Florian Schönewald,Marcel Risch,Marcel Risch,Cynthia A. Volkert,Peter E. Blöchl,Peter E. Blöchl,Jörg Behler +7 more
TL;DR: In this article, a DFT-based high-dimensional neural network potential (HDNNP) is proposed to predict a series of properties like the lattice parameters and expansion with increasing Li content or temperature, the orthorhombic to cubic transition, the lithium diffusion barrier, and the phonon frequencies.

Single crystal growth of the spinel-type LiMn2O4
TL;DR: In this paper, single crystals of the spinel-type LiMn 2 O 4 have been successfully grown by a solvent evaporation flux method at 1173 K and the maximum size of the octahedral-shaped single crystal is 0.09 x 0.

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.
