Abstract

Lithium has been electrochemically extracted and inserted fromLixNi0.8Co0.2O2 (0{less than or equal to}xLi{less than or equal to}1) using a dedicated electrochemicalcell. The behavior of this cathode material for lithiumbatteries was studied by in situ-X-ray diffraction usingsynchrotron radiation and analyzed by Rietveld refinement.Besides the accurate determination of the lattice parametersduring cycling, an anisotropic broadening of specificreflections, most pronounced around xLi=0.1, is observed andattributed to reversible microstructural changes at this highdegree of lithium extraction.
