In recent years there has been great interest in fast ion conducting solids which represent interesting materials that can be used for the development of various electrochemical solid-state devices such as batteries. Nowadays, special attention is paid to the glasses containing Li+ cations. Because lithium is a light and highly electropositive element that is favorable for the fabrication of solid state electrolyte. In the present work a systematic study for different samples in glassy system lithium lead borate, having different molar composition is carried out. Also some glasses containing Ag2O and / or Cu2O in replacement of Li2O are studied.
