First-Principles Modeling of Mn(II) Migration above and Dissolution from LixMn2O4 (001) Surfaces
TL;DR: In this paper, density functional theory and ab initio molecular dynamics simulations are applied to investigate the migration of Mn(II) ions to above-surface sites on spinel LixMn2O4 (001) surfaces, the subsequent Mn dissolution into the organic liquid electrolyte, and the detrimental effects on graphite anode solid electrolyte interphase (SEI) passivating films after Mn(2) ions diffuse through the separator.

Vinylene Carbonate and Li Salicylatoborate as Additives in LiPF3 ( CF 2 CF 3 ) 3 Solutions for Rechargeable Li-Ion Batteries
TL;DR: In this paper, the effect of additives on the electrodes' performance can be clearly attributed to their impact on the surface chemistry of these electrodes, and it was found that LiFAP solutions containing VC were superior for both graphite and (spinel) electrodes.
Journal ArticleDOI
Oxygen Reduction Reaction Using MnO2 Nanotubes/Nitrogen-Doped Exfoliated Graphene Hybrid Catalyst for Li-O2 Battery Applications
TL;DR: In this paper, an α-MnO2 NT/NExG composite was shown to demonstrate excellent oxygen reduction reaction (ORR) activity in an aprotic non-aqueous electrolyte Li-O2 cell.
Journal ArticleDOI
Microwave-assisted green synthesis of MnO2 nanoplates with environmental catalytic activity
TL;DR: In this article, MnO2 nanoplates were synthesized in aqueous solution under the microwave irradiation, without using any templates, catalysts, and organic reagents.
Journal ArticleDOI
Morphology controlled MnO 2 electrodeposited on carbon fiber paper for high-performance supercapacitors
TL;DR: In this paper, four different morphologies of nanostructured MnO2 (nanospheres, nanosheets, nanoflowers and nanonods) were fabricated on a carbon fiber paper (CFP) substrate using a facile method of anodic electrodeposition by varying the H2SO4 concentration and current density.

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.
