Synthesis, characterization, and catalytic activity of cryptomelane nanomaterials produced with industrial manganese sulfate.
TL;DR: This investigation will provide fundamental information for developing a large-scale production process for transforming manganese sulfate to cryptomelane and showed improved catalytic activity for decomposition of hydrogen peroxide as compared with natural cryptmelane, but lower than those synthesized with hydrothermal and sol-gel methods.

Simple synthesis of a double-shell hollow structured MnO2@TiO2 composite as an anode material for lithium ion batteries
TL;DR: A double-shell hollow structured MnO2@TiO2 anode material has been successfully synthesized through a two-step template method in this paper, where the inner part of the carbon template acts as a sacrificial template to form the void and the outer part of it plays the role of self-template to synthesize hollow MnO 2 spheres.

Ki Soo Park,Myung Hun Cho,Sang Ho Park,Kee Suk Nahm,Yang-Kook Sun,Yun-Sung Lee,Masaki Yoshio +6 more
TL;DR: Li0.7[Ni1/6Mn5/6]O2 has two plateaus similar to those observed from a spinel structure, but Li0.5[Ni 1/6mn 5/6 ]O2 holds a single plateau as observed from typical layered structure as mentioned in this paper.
Journal ArticleDOI
Chemical vs. electrochemical extraction of lithium from the Li-excess Li1.10Mn1.90O4 spinel followed by NMR and DRX techniques
TL;DR: A generalized chemical reaction has been proposed to explain the formation of intermediate Li(+) de-intercalated samples during acid treatment in aqueous media.

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.
