Abstract
Synthesis of various X-birnessites was performed using the ion exchang e properties of the sodium birnessite Na0.32MnO2,yH(2)O. Their structu ral and electrochemical characteristics are investigated and discussed in comparison with previous data obtained for some compounds and in r elation with mechanism invoked for Li electrochemical insertion into s ol-gel and chemical birnessites. Two main groups of materials are obta ined with a monoclinic or hexagonal structure depending on the kind of inserted cation.
