Ag~2O nanoparticles used for active electrode materials have first been successfully prepared by various chemical methods and conventional Ag~2O particles for comparison are prepared as well. The above samples were examined and characterized with TEM, XRD and XPS test techniques. The formation mechanism of Ag~2O nanoparticles by each method has also been proposed, which indicates that the nanoparticles preparation methods, can be used for other oxides preparation with some practical and universal significance.
