Internal alternating current (AC) preheating is considered as an effective preheating method to use or charge lithium batteries at low temperatures.In this study,a temperature feedback internal AC preheating method avoiding lithium deposition for lithium batteries is developed in three steps:(1) The electrochemical impedance spectroscopy (EIS) data of both positive and negative electrodes is measured at different temperatures using a three-electrode lithium battery.
