Abstract
|
|
|
|
Lithium and sodium ions have been intercalated into two dimensional structure of FeMoO4Cl. The electronic localization and the large difference in unit cell parameter between the pristine material and the intercalates lead to the existence of large biphased domains. In the case of the lithium system, a narrow range of LixFeMoO4Cl (0.95≤x≤1.06) solid solution has been found around the LiFeMoO4Cl composition. The OCV curve fitting has been performed using Armand's model. The occurrence of several parts in the charge-discharge curve is related to the electronic and structural modifications of the material during the intercalation process.
