Synthesis and characterization of single-crystalline nanorods of α-MnO2 and γ-MnOOH
TL;DR: In this paper, single-crystalline α-MnO 2 nanorods were prepared by reducing KMnO 4 with graphite in concentrated H 2 SO 4 solution at 0°C.
Journal ArticleDOI
Facile synthesis of porous LiMn2O4 spheres as cathode materials for high-power lithium ion batteries
TL;DR: In this paper, a facile topochemical route was developed to synthesize porous LiMn2O4 spheres by using molten LiOH and porous Mn2O3 spheres as a template.
Journal ArticleDOI
Numerical Simulation of the Effect of the Dissolution of LiMn2O4 Particles on Li-Ion Battery Performance
TL;DR: Park et al. as discussed by the authors performed a numerical simulation of the effect of the dissolution of LiMn2O4 particles on Li-Ion battery performance and found that dissolution significantly reduced battery performance.
Journal ArticleDOI
Surface structure sensitivity of manganese oxides for low-temperature selective catalytic reduction of NO with NH3
TL;DR: In this article, the results of the catalytic tests revealed that both K-Hol and H-Hol with almost same catalytic activities had much higher reaction rates than β-MnO2 under the same conditions, and even at a high gas hourly space velocity of 160,000h−1, KHol obtained more than 90% conversions of NO in a wide temperature window of 100-300°C.

MnO2 Nanorod Supported Gold Nanoparticles with Enhanced Activity for Solvent-free Aerobic Alcohol Oxidation
TL;DR: In this paper, a combination of different techniques (N2 adsorption, X-ray diffraction (XRD), transmission electron microscopy (TEM), hydrogen temperature-programmed reduction (H2-TPR), and Xray photoelectron spectroscopy (XPS) was used to characterize gold nanoparticles supported on β-MnO2 with different morphologies, i.e., nanorods and conventional particulates.

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.
