A new comoposite electrolyte Ag/AgI/Ag has been developed by a Physical vapour deposition (PVD) technique. Ag have been deposited in both sides of the coin type-superionic conductor AgL with depositon time 30, 45 and 60 minutes. Several characterizations on deposited Ag/AgI/Ag suchas the crystal structure, micro structure, hardness, density, and the ionic conductvity have been performed by using respectively, an X-ray Diffactometer, Scanning Electron Microscope/EDAX, Micro Hardness Tester, Pycnometer and Impedance Spectroscopy. The x-ray pattern at room temprature for deposited Ag/AgI/Ag does not show any phase transformation and the structure is dominated by Y-Agl, with the particle size is about 27.3 nm. There is a significant increase in ionic conductivity from 10 pangkat -6 S/cm to 10 pangkat -3 S/cm. The increase of the ionic conductivity is possibly due to the increasing number of Ag from 48.62% to 64.04% in the new composite Ag60'/AgI/Ag60' as confirmed bu the result from EDAX. The microstructure measured by SEM shows an expansion of the matrix AgI after deposited byAg. With increasing deposition time, the hardness increases, while the density decreases.
