1. SOLID STATE ELECTROCHEMISTRY SUBJECT REVIEW Schedule: Friday 12.30 – 14.15 WIB, Room By Dr. Fitria Rahmawati ( Research Group of Solid State & Catalysis )

2. Introduction a brief history of solid state electrochemistry

3. Solid Electrolyte Electrolyte is a substance that conduct electricity through the movement of ions Figure. Some examples of solid electrolyte application

4. Ionic vs electronic conductivity Metals ▫Conductivity Range = 10 S/cm <  < 10 5 S/cm ▫Electrons carry the current ▫Conductivity Increases linearly as temperature decreases (phonon scattering decreases as T  ) Solid Electrolytes ▫Conductivity Range = 10 -3 S/cm <  < 10 S/cm ▫Ions carry the current ▫Conductivity decreases exponentially as temperature decreases (activated transport)
