Battery Failure Mode: Negative Plate Sulfation
When a lead-acid battery is left to self-discharge (in storage or installed but seldomly used) or is exposed to excess and repeated high-rate charging (such as is the case with Start-stop vehicles), a point can be reached where the reaction at the negative plate that should convert the lead back to active material (PbSO4 back to Pb) can not accommodate all of the charging currents.

6 FAQs about [New Energy Battery Negative Plate]
What is a negative plate?
G. Papazov, in Encyclopedia of Electrochemical Power Sources, 2009 The negative plate consists of negative lead grid and negative active mass (NAM). The lead grid supports the negative active material and it is a current conductor for the electricity generated in the negative active material, as well as a conductor for the charge current.
What is the difference between positive and negative plates on a battery?
If you’re talking about a car battery, the positive plate is usually more in “battery” than the negative plate. The negative plate typically has more sulfate build-up on it, which can reduce its effectiveness. How Many Negative Plates Does a Lead Acid Battery Have? A lead acid battery has two negative plates.
Why do lead acid batteries have more negative plates than positive?
Lead acid batteries have more negative plates than positive due to the way they are made. The negative plates are made of lead oxide, while the positive plates are made of pure lead. The lead oxide is heavier than the lead, so it takes up more space on the plate. That’s why there are more negative plates in a lead acid battery.
What is a lead battery plate?
The negative and positive lead battery plates conduct the energy during charging and discharging. This pasted plate design is the generally accepted benchmark for lead battery plates. Overall battery capacity is increased by adding additional pairs of plates. A pure lead grid structure would not be able to support the above framework vertically.
