Abstract

See full text

A deformation detection apparatus includes a cell movement-control assembly to handle a linear motion and a rotational motion of a battery cell, a body that supports the cell movement-control assembly, a digital micrometer, and control circuitry. The control circuitry controls a displacement of the battery cell between a first position and a second position along a longitudinal axis through a scanning region of the digital micrometer and a plurality of rotational positions of the battery cell at a plurality of charge states and a plurality of discharge states. The control circuitry measures a plurality of outer diameter values of the battery cell for a plurality of linear positions and a plurality of rotational positions along the longitudinal axis of the battery cell and determines a change in a geometrical shape (deformation and/or strain) of the battery cell for the plurality of linear positions and the plurality of rotational positions.
