- •
Detection of lithium plating by voltage relaxation, stripping discharge and EIS.
- •
Adapted differential voltage method enables resolving lithium depletion process.
- •
Voltage relaxation shows characteristics comparable to stripping discharge.
- •
A reversible shrinking of the cell's impedance after the plating event is observed.
- •
Correlation of adapted differential voltage and impedance characteristics is found.
