Abstract

A method includes determining a total expansion value for a coin cell based on processing of first sensor data captured by a magnetic force dilatometry sensor. The first sensor data is representative of the coin cell during a cycling program of the coin cell with the coin cell held at a fixture. Based on processing of second sensor data captured by an imaging sensor, the method includes determining a reversible expansion value for the coin cell. The second sensor data is representative of the coin cell during the cycling program of the coin cell with the coin cell held at the fixture. Based on the total expansion value and the reversible expansion value, the method includes determining an irreversible expansion value for the coin cell.
