Can lead acid battery be recharged after over discharge?
However, conventional lead acid battery cannot be recharged after over discharge and the performance is greatly declined. It has been revealed that the cause of not being able to be recharged is the formation of α-PbO 2 on the surface of β-PbO 2 cathode active material due to local cell reaction between lead current collector and β-PbO 2.
Do open circuit voltage and energy recovery of lead acid batteries affect health?
It was demonstrated that the magnitudes of open circuit voltage and energy recovery of lead acid battery have relationships with the health status of the battery which if well exploited, can lead to innovations in the science of state of health determination for lead acid batteries.
What causes degradation of conventional lead acid battery when discharged deeply?
Degradation of conventional lead acid battery when discharged deeply is caused by the formation of α-PbO 2 on β-PbO 2 cathode active material due to local cell reaction between β-PbO 2 and lead current collector on cathode. The formation of α-PbO 2 was prevented by using graphite sheet as cathode current collector.
How to prevent the formation of -PbO 2 in lead acid battery?
Formation of α-PbO 2 is prevented by using gold as the current collector. In this study, we developed the lead acid battery with high resistance to over discharge using graphite materials as current collector. The formation of α-PbO 2 was prevented by using expanded natural graphite sheet as cathode current collector.
Why are lead acid batteries kept at open circuit voltage for 800 Min?
The batteries were chosen to be kept at open circuit voltage for 800 min because some works have shown that for lead acid batteries, the state of charge can be derived at open circuit voltage when the battery is disconnected from the load for at least two hours and this OCV is linearly proportional to the Depth of Discharge (DOD) .
Does a lead-acid battery over-discharge?
Despite of the fact that the lead-acid battery is a 150-year-old system, its over-discharge characteristic is a less investigated area. During this process, different reactions can occur which lead to the aging of the battery (for example sulfation, loss of active mass or loss of water) [1-4].
