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.

Phase diagram of LixC6.
TL;DR: Transitions to stage 3, to a ``liquidlike'' stage-2 phase (denoted 2L), to stage 2, and finally to filled stage 1 occur sequentially as expected on the basis of previous work.

An Investigation of Lithium Ion Insertion into Spinel Structure Li‐Mn‐O Compounds
Yongyao Xia,Masaki Yoshio +1 more
TL;DR: In this paper, two kinds of spinel structure lithium manganese oxides obtained by a melt-impregnation method were examined in a lithium nonaqueous cell and the mechanism of the lithium ion insertion into the spinel compound was studied by several physical and chemical methods (differential chronopotentiometric curves, cyclic voltammetry, and opencircuit voltage measurement) X-ray diffraction was also used to investigate the structural changes for both types of compounds at different oxidation depths at first charge.
