Fundamental Thermodynamic Limitations in Wagner’s Equation in Solid State Electrochemistry

The use of samarium-doped ceria (SDC) electrolytes in SOFCs (solid oxide fuel cells) lowers the open circuit voltage (OCV) below the Nernst voltage (Vth), which is obtained using yttria-stabilized zirconia (YSZ) electrolytes. The OCV is classically calculated with Wagner’s equation. However, using SDC electrolytes requires both qualitative and quantitative experimental verification of leakage c...

Lecture II : Fundamental concepts in solid state

In the figure above, we see a lattice of black and white atoms. These could be B and N atoms respectively for a BN-sheet. Using one of the equivalent unit cells (hashed area) and combinations of the unit vectors, ~a1 and ~a2, we can generate the entire lattice. A general translational vector in a periodic lattice can be written as the sum of integer multiples of unit vectors, ~ T (~n) = ~ T (n1...

Al-Air Batteries: Fundamental Thermodynamic Limitations from First-Principles Theory.

The Al-air battery possesses high theoretical specific energy (4140 W h/kg) and is therefore an attractive candidate for vehicle propulsion. However, the experimentally observed open-circuit potential is much lower than what bulk thermodynamics predicts, and this potential loss is typically attributed to corrosion. Similarly, large Tafel slopes associated with the battery are assumed to be due ...
