BU-804a: Corrosion, Shedding and Internal Short

Corrosion occurs primarily on the grid, and it is known as a "softening and shedding" of the lead off the plates. This reaction cannot be avoided because the electrodes in a lead acid environment are always reactive. Lead shedding is a natural phenomenon that can be reduced but not eliminated.

Aging mechanisms and service life of lead–acid batteries

The phenomenon called "sulfation" (or "sulfatation") has plagued battery engineers for many years, and is still a major cause of failure of lead–acid batteries. The term "sulfation" described the condition of a battery plate, in which highly crystalline lead sulfate has formed in an practically irreversible manner. This type of lead sulfate cannot, or only partially,

Causes of Short Circuits in Lead-Acid Batteries

A short circuit in lead-acid batteries occurs when there is an unintended connection between the positive and negative terminals, allowing current to flow directly between them.

How is the Al-Cu short circuit triggered?

The Al-Cu type was triggered by removing both the active material for cathode and anode, and the ISC device was placed at the vacancy of the anode (Copper). At normal state, the Al-Cu short circuit is blocked by separating the naked Al foil and the SMA device by the separator.
