Understanding the intricacies of passivation in batteries is crucial. Self-discharge is a common occurrence due to chemical reactions that deplete energy even when a battery is inactive. The self-discharge rate is influenced by various factors, with passivation playing a significant role. Passivation involves the formation of a thin film of lithium chloride on the lithium anode's surface, limiting chemical reactions. This process creates initial high resistance when a load is applied, causing a temporary voltage dip until the passivation layer is removed during discharge. Factors like current capacity, storage duration, and discharge conditions affect passivation levels. The impact of passivation is more pronounced when a load is removed from a partially discharged cell compared to a new one. Understanding these dynamics is key in optimizing battery performance.
