Abstract
A method of performing a high-temperature aging process of a rechargeable cell () comprising an anode (), a cathode (), an electrolyte () and a separator (), is provided. The method includes heating a solid electrolyte interface () formed on the anode () to a predetermined temperature at which a saturated ionic conductivity of the solid electrolyte interface () is elevated, and holding the solid electrolyte interface () at the predetermined temperature for a predetermined minimum time at which ionic conductivity of the SEI becomes saturated.
