Understanding the aging mechanism for lithium-ion batteries (LiBs) is crucial optimizing battery operation in real-life applications. This article gives a systematic description of LiBs electric vehicle (EV) First, characteristics common EVs and chemistries used these applications are described. The then classified into three modes: charging, standby, driving, which subsequently Finally, behavior actual driving modes reviewed, influence different working conditions considered. degradation mechanisms cathode, electrolyte, anode during those processes also discussed. Thus, analysis EV achieved, providing practical guidance, methods to prolong life users, designers, manufacturers, material recovery companies.
