Abstract
Structural changes in a promising cathode material LiNi0.8Co0.1Mn0.1O2 for lithium-ion batteries were in situ studied by X-ray diffraction analysis in the course of electrochemical reactions. The Rietveld method and TOPAS 5 software package were used to examine changes in the unit cell parameters of LiNi0.8Co0.1Mn0.1O2 and the reasons for these changes. It was found that the unit cell volume increases by 2% relative to the discharged state (2.7 V) upon charging to 4.2 V.
