Using Green's Functions to Understand the Stresses on a Li-air Battery Electrode

John H Summerfield

In this work the growth of a Li electrode-electrolyte interface in the presence of an elastic prestress is studied. In particular the focus is on Li-air batteries with a solid electrolyte, LIPON. Theoretical studies and experimental evidence show that during the process of charging the battery the replated lithium adds unevenly to the electrode surface. This eventually leads to dendrite formation as the battery is charged and discharged numerous times. This study focusses on the deviation from flatness of the electrode and the surface Green’s function is also developed. It was found that the theoretical formulation is in line with the literature.
