Mechanisms of Aging in EV Batteries
The aging of EV batteries occurs through several mechanisms that ultimately degrade their performance, capacity, and lifespan. These processes can be broadly categorized into structural and electrochemical changes that take place within the battery cells over time.
One primary mechanism involves the formation of a solid electrolyte interphase (SEI) layer on the anode surface. While this layer helps to stabilize the electrolyte, it can also grow thicker with repeated cycles, which can impede lithium-ion flow, thereby reducing efficiency and increasing internal resistance.
Another significant factor is the mechanical stress related to volume changes during charge and discharge cycles. As batteries undergo these cycles, the anode and cathode materials expand and contract, which can lead to microcracking. This damage compromises the integrity of the electrodes and can contribute to capacity fade.
Temperature fluctuations further exacerbate these aging mechanisms. Elevated temperatures accelerate chemical reactions that can lead to electrolyte degradation and loss of active material.

Charge and Discharge Cycles
Charge and discharge cycles refer to the processes during which an electric vehicle’s battery is charged and subsequently discharged to power the vehicle. Each cycle exerts mechanical and chemical stress on the battery cells, contributing significantly to the overall aging process. Understanding these cycles is vital for assessing how research on aging batteries affects electric vehicle lifespan.
During the charging process, lithium ions move from the cathode to the anode, while during discharge, they return to the cathode. Repeated cycling can lead to the formation of solid electrolyte interphase (SEI) layers, which hinder ion movement and reduce overall capacity. The cumulative effect of these cycles ultimately results in diminished battery performance.
The depth of discharge, frequency of charging, and duration spent at various states of charge can further influence aging. For instance, frequently depleting the battery to a low state of charge before recharging can accelerate degradation, underscoring the importance of optimal charging practices.
