Li2SO4: LiNbO3 binary system for solid state battery applications
Different compositions in the Li2SO4-LiNbO3 system have been prepared by adopting the twin roller quenching technique. The electrical conductivity has been measured and the sample with 20 mole% LiNbO3 exhibited maximum conductivity at 573 K. The results have been explained on the basis of XRD, SEM data and vacancy concentration. A number of solid state electrochemical cells were fabricated by varying the electrolyte composition, using Li-metal and MnO2 as anode and cathode respectively. The 80 Li2SO4:20 LiNbO3 composition gave the best cell performance.
