In Situ Measurements of Stress-Potential Coupling in Lithiated Silicon
In Situ Measurements of Stress-Potential Coupling in Lithiated Silicon
An analysis of the dependence of electric potential on the state of stress of a lithiated-silicon electrode is presented. Based on the Larché and Cahn chemical potential for a solid solution, a thermodynamic argument is made for the existence of the stress-potential coupling in lithiated silicon; based on the known …
