Assumptions usually adopted were that the charge was slow and lithium concentration was always uniform in electrodes, leading to the incapability of describing the stress effects on voltage hysteresis under consecutive thermodynamically non-equilibrium states where both lithium concentration and stress are not uniform.
In real electrodes of lithium ion batteries, the compression among particles and the restriction of electrode structure would give rise to the compressive stresses. Therefore, it is believed that the stress effects on voltage hysteresis presented in this paper is a conservative estimation.
