Kirst et al. Estimate Half-Cell Electrode Potentials And Degradation Modes Throughout A Batteryʼs Lifetime, Enabling Non-Destructive Degradation Mode Analysis - No Half Cells!

Degradation mode analysis traditionally requires extracting samples of both negative and positive electrodes, and then carefully constructing half-cells versus metallic lithium to measure electrode potential curves, limiting degradation mode analysis to cases where destructive characterization of cells is possible. Kirst et al. 1] develop a method to non-destructively estimate electrode potential curves as well as LLI and LAM throughout battery lifetime. This method enables performing degradation mode analysis on any cell without any destructive characterization of the electrode materials.
