The electrochemical deintercalation of AMOz compounds, where A = Li or Na, and M = Cr, Co or Fe, was investigated. The open circuit voltage of A/lM AClO%-propylene carbonate/A,MOz cells and the chemical diffusion constant, D, of alkali in AXM02 were measured using a currentpulse relaxation technique

Unpolarized and polarized Raman spectra (200-800 cm-1) of with a layered rock-salt structure were LiCoO 2 measured. The Raman-active lattice modes of were assigned by polarized Raman measurements of a LiCoO 2 c-axis oriented thin Γlm. The variation of the Raman spectra of powder prepared by electroc
MnO 2 was chemically prepared from birnessite (CMD 2D ) and from spinel-like LiMn 2 O 4 (CMD 3D ) by acid leaching. X-ray diffractometry, FTIR spectrometry, chemical and thermal analyses were used to determine the structure and chemical disorder. On the basis of cation vacancy model, the structural
The electrochemical study of LiCr III y Mn III 1!y Mn IV O 4 compounds, 04y41, between 3.5 and 5.4 V vs Li metal, shows that the Cr substitution is beneficial to the overall performances (capacity, specific energy, and cyclability) for y40.62, and that y"0.25 gives the best results. For y'0.62, the
