Lead-acid battery failure model

May , 11 2024

The most common failure modes are: - Softening or shedding of the active material. During discharge the lead oxide (PbO2) of the positive plate is transformed into lead sulfate (PbSO4), and back to lead oxide during charging. Frequent cycling will reduce cohesion of the positive plate material due to the higher volume of lead sulfate compared to lead oxide. Corrosion...

Advantages of Nickel-Cadmium Batteries

May , 31 2024

Ni-Cd batteries have been around nearly as long as lead-acid. Commercial products have been available since around 19007. Pocket plate designs are typically used for long to high current types, while fiber plates are used for extremely high current short demand applications like engine starting. While Ni-Cd batteries typically cost many times what a comparable lead-acid does, their characte...
