Each aging mechanism has an impact on the behavior of the battery. The impact can be broken down into two performance parameters: capacity and internal resistance. Batteries lose capacity when they age. For an electric vehicle, losing capacity means the EV cannot drive as far as it used to without stopping for a recharge.
The aging of batteries is significantly influenced by the charging and discharging rates. During the charging and discharging process, heat in the battery originates from Joule heat, chemical reactions, and phase transitions.
They established a model for uneven heat production of batteries, revealing that higher rates result in increased temperature distribution unevenness within the battery. This, in turn, leads to uneven lithium plating on the surface of the anode, accelerating battery aging.
Battery degradation poses significant challenges for energy storage systems, impacting their overall efficiency and performance. Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy.
