In-Situ Raman Spectroscopy of Single Microparticle Li-Intercalation Electrodes
TL;DR: In this paper, the vibrational properties of a single microparticle of LiMn2O4 induced by extraction and subsequent injection of Li(+) into the lattice have been monitored in situ via simultaneous acquisition of Raman scattering spectra and cyclic voltammetry data in 1M LiC1O4 solutions in ethylene carbonate (EC):diethyl carbonate mixtures (1:1 by volume).

Microstructural and spectroscopic investigations into the effect of CeO2 additions on the performance of a MnO2 aqueous rechargeable battery
Manickam Minakshi,David R. G. Mitchell,Melody L. Carter,Dominique R. T. Appadoo,Kalaiselvi Nallathamby +4 more
TL;DR: In this article, the influence of CeO2 additions on the electrochemical behaviour of the MnO2 cathode in a Zn-MnO2 battery using LiOH as an electrolyte was investigated using microscopy and spectroscopic techniques.

Synthesis and crystal chemistry of microporous titanates K x (Ti, M ) 8 O 16 where M =Sc–Ni
Pouya Moetakef,Amber M. Larson,Brenna C. Hodges,Peter Y. Zavalij,Karen J. Gaskell,Philip M. Piccoli,Efrain E. Rodriguez +6 more
TL;DR: In this article, single crystal and powder X-ray diffraction reveals phase pure hollandite-type titanates with tetragonal space group I4/m, which are microporous oxides with 1-dimensional channels where the non-framework cation, K, resides.

Phase states of Li/W/Mn/SiO2 composites in catalytic oxidative coupling of methane
TL;DR: In this article, phase diagrams of Li2O-WO3-MnO3/MnN2O3 composite catalysts have been mapped out and shown to be in melt-mn2O 3-quartz (cristobalite) equilibrium at temperatures of oxidative coupling of methane.
Journal ArticleDOI
Synthesis and electrochemical properties of nanosized LiFeO2 particles with a layered rocksalt structure for lithium batteries
TL;DR: LiFeO 2 particles with average particle sizes of ca. 40 and 400 nm were synthesized by an ion exchange reaction from α-NaFeO2 precursors as mentioned in this paper.

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.

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.
