Investigation of the Effect of Extra Lithium Addition and Postannealing on the Electrochemical Performance of High-Voltage Spinel LiNi0.5Mn1.5O4 Cathode Material
TL;DR: In this article, the effects of extra amounts of lithium addition and postannealing process on the physicochemical and electrochemical properties of the spherical LNMO material were investigated, and the experimental results show that the amount of lithium and the postanneal process have significant impacts on the Mn3+ content, phase impurity (rock-salt phase) and phase structures (Fd3m and P4332), so as their electrochemical performance.
Journal ArticleDOI
Electrochemical characteristics of manganese oxide/carbon composite as a cathode material for Li/MnO2 secondary batteries
TL;DR: In this paper, an EMD/C(Super P) composite heat-treated at 400°C after high-energy mechanical milling shows better electrochemical performance than that of pure EMD in terms of cycleability and capacity fading.
Journal ArticleDOI
Single-crystalline LiMn2O4 nanorods as cathode material with enhanced performance for Li-ion battery synthesized via template-engaged reaction
TL;DR: In this paper, single-crystalline LiMn 2 O 4 nanorods with a diameter of ~100nm were synthesized via a template-engaged reaction by using tetragonal β-MnO 2 nanorod as starting material.

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.

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.
