Journal ArticleDOI
Unraveling manganese dissolution/deposition mechanisms on the negative electrode in lithium ion batteries
TL;DR: A new interpretation of how Mn is reduced from the cathode and how metallic Mn and Mn-bearing nanoparticles form within the SEI during electrochemical cycling is proposed.
Journal ArticleDOI
Performance of High Energy Density Symmetric Supercapacitor Based on Sputtered MnO2 Nanorods
TL;DR: In this article, a symmetric supercapacitor device in form of α-MnO2 nanorods/Ag/AAO electrode has been fabricated, characterized and its performance has been investigated in detail.
Journal ArticleDOI
The role of electronic and ionic conductivities in the rate performance of tunnel structured manganese oxides in Li-ion batteries
TL;DR: In this article, single nanowires of two manganese oxide polymorphs were isolated onto nanofabricated platforms using dielectrophoresis, which was found to be higher in α-MnO2 as compared to that of todorokite phase by a factor of ∼46.
Journal ArticleDOI
Single-Step Synthesis, Characterization, and Application of Nanostructured KxMn1-yCoyO2-δ with Controllable Chemical Compositions and Crystal Structures
Sun Hee Lee,Tae Woo Kim,Dae Hoon Park,Jin-Ho Choy,Seong Ju Hwang,Nanzhe Jiang,Sang Eon Park,Young Ho Lee +7 more
TL;DR: In this article, cobalt-substituted manganese oxide one-dimensional (1D) nanowires have been synthesized through one-pot hydrothermal treatment of the ion pair solution of Co2+ and MnO4-, along with their threedimensional (3D) hierarchically assembled microspheres.
Journal ArticleDOI
Revealing the Reconstructed Surface of Li[Mn2]O4.
Charles D. Amos,Manuel A. Roldan,Maria Varela,Maria Varela,John B. Goodenough,Paulo J. Ferreira +5 more
TL;DR: The atomic structure coupled with Mn-valence and the distribution of the atomic ratio of oxygen obtained by electron energy loss spectroscopy reveals a thin, stable surface layer of Mn3O4, a subsurface region of Li1+x[Mn2]O4 with retention of bulk Li[ Mn2?]O4.

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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
