The elevated temperature performance of LiMn2O4 coated with LiNi1−XCoXO2 (X = 0.2 and 1)
TL;DR: In this article, the surface of LiMn 2 O 4 was covered with fine LiNi 1− X Co X O 2 (X =0.2 and 1) particles. But, the performance of the surface was not improved.
Journal ArticleDOI
Conformal electrodeposition of manganese dioxide onto reticulated vitreous carbon for 3D microbattery applications
TL;DR: In this paper, the authors used a 100 ppi compressed RVC to increase the surface area of a 2 mm-thick EMD conformal film with a capacity per footprint area increase of 250.
Journal ArticleDOI
The study of lithium ion de-insertion/insertion in LiMn2O4 and determination of kinetic parameters in aqueous Li2SO4 solution using electrochemical impedance spectroscopy
TL;DR: In this article, an equivalent circuit distinguishing the kinetic parameters of lithium ion de-insertion/insertion is used to simulate the experimental impedance data and fitting results are in good agreement with the experimental results and the parameters of the kinetic process of Li+ deinsertion and insertion in LiMn2O4 at different potentials during charge and discharge are obtained using the same circuit.

Li1.01Mn1.97O4 surface modification by poly(3,4-ethylenedioxythiophene)
TL;DR: In this paper, the electrochemical characterization of non-stoichiometric LiMn2O4 spinels (commercial and home-made via the sol-gel route) covered by poly(3,4-ethylenedioxythiophene) (pEDOT) chemically grown on the oxide particle surface and of spinels without polymer covering for use in lithium-ion batteries is presented.
Journal ArticleDOI
Quantitatively Predict the Potential of MnO2 Polymorphs as Magnesium Battery Cathodes
TL;DR: By evaluating the reaction free energy, structural deformation associated with the insertion of magnesium, and the diffusion barriers, a quantitative evaluation about the feasibility of magnesium intercalation can be well established, paving the road to identify better cathode candidates in future.

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.

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.
