Abstract: This work investigates how the mechanical response of lithium-ion batteries evolves with aging and demonstrates how mechanical measurements can be used to estimate degradation mechanisms, presenting interesting advantages over traditional voltage-based methods. A lithium cobalt oxide-graphite battery was cycled over 1,000 times to a state of health of 70%, with periodic performance tests measuring capacity, resistance, voltage, temperature, and deformation during the charge/discharge cycles. The deformation measurements can be distinguished into a reversible component (expansion during charge recovered with the shrinkage during discharge) and an irreversible component (increase of the battery thickness through aging).
