I aim to improve the electrochemical phase field modeling to predict the deposition/dissolution phenomena in various electrochemical systems. 

Mechanically hard solid-state electrolytes are expected to effectively suppress Li dendrite formed on the Li metal anode surface due to their impressive elastic modulus. However, several experiment observations show otherwise. The differences in mechanical and electronic properties between the grain boundary and the bulk grain are the key. The Li morphology is primarily controlled by such an interfacial stress difference induced by the mismatch of the elastic (or plastic) properties between GB and grain. In addition, excess electrons trapped in GB trigger Li nucleation far from the Li metal surface.

Mechanical stress impacts the corrosion behavior by shifting the potential of the metal electrode. The (external and residual) stress contribution to the dissolution process is taken into account. The temporal evolution of stress and the corrosion pit morphology is simulated.
