Prospects for refurbishing and recycling energy storage technologies such as lead acid batteries (LABs) prompt a better understanding of their failure mechanisms. LABs suffer from a high self-discharge rate accompanied by deleterious hard sulfation processes which dramatically decrease cyclability. Furthermo
Effects of rest time on discharge response and equivalent circuit model for a lead-acid battery☆
Some investigations were conducted on the effects of rest time on the Thevenin''s equivalent circuit model of the subsequent discharge for a lead acid battery. It was revealed that the initial voltage of the dominant capacitor does not go to 0, even after a sufficiently long rest, but goes to a negative number.

Batteries | Free Full-Text | Heat Effects during the Operation of Lead-Acid Batteries …
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as "thermal runaway." This …
