Abstract

Lithium-ion batteries are widely used, from lightweight to energy-intensive, from small devices to large ESSs. However, it is sensitive to the surrounding environment and there is a change in performance depending on the temperature change. In this study, the temperature dependence of the charge / discharge characteristics of the battery is shown through simulation and the distribution of the salt concentration in the electrolyte is observed when the sudden temperature change is applied.
