Studies of lithium phosphoantimonite glassy system
Abstract Electrical and thermal characterization of the lithium phosphoantimonite glassy system has been made over a wide frequency, temperature and composition range. An order of magnitude difference was observed in electrical conductivity between bulk glass and pressed pellet. The electronic conductivity at 100°C is at least 3 orders of magnitude smaller than the ionic one. The cell characterization has been made on charge and discharge cycles under different resistive loads with a few cells by using the highly-conducting composition glass as solid electrolyte, lithium metal as anode and TiS2 as cathode. The EMF of the cell was also determined for the cell configuration Li/glass electrolyte/Cu+CuCl+LiCl. The open circuit voltage which was found constant over a prolonged period is indicative of the electrochemical stability of the cell.
