Introduction The separator is one of the most critical components of the lead/acid battery. Too often, however, its role in determining the performance and life of the battery is ignored.
When the battery is charging the ions moves from cathode to anode and when the battery gets discharged the ions will move in the reverse direction. The separator controls the number of ions moving between the positive and negative terminal and hence it is responsible for the leakage of ions (self-discharge) when the battery is ideal.
Another important part of a battery that we take for granted is the battery separator. These separators play an important role in deciding the functionality of the battery, for examples the self-discharge rate and chemical stability of the battery are highly dependent on the type of separator used in the battery.
For example, the Li-ion battery's separator directly affects how the battery performs. The separator is one of the most critical inner layer components in the structure of lithium batteries. The quality of its performance directly affects the capacity, rate, life and safety of the battery.
As a result separators were no longer the age-limiting mechanisms for lead acid batteries, and conductivity effectively doubled again. Polyethylene systems improved the overall porosity to levels previously realized by natural rubber systems while maintaining the mechanical advantages of PVC.
Lead acid batteries pose the following challenges to a separator. Both anode and cathode are subject to shape change and possible embrittlement, so the separator must be compliant enough to accommodate this type of change while also preventing material crossover.
BU-306: What is the Function of the Separator?
Battery separators provide a barrier between the anode (negative) and the cathode (positive) while enabling the exchange of lithium ions from one side to the other. Early batteries were flooded, including lead acid and nickel-cadmium.
