Definition
A battery separator is a thin, porous material which acts as a barrier between the anode and cathode. The battery separator maintains the uniformity of electrolytes within the electrolyte solution; it allows ion flow freely between the anode and cathode, and prevents electrons from flowing through, forcing them to follow a designed pathway around the separator, and provides mechanical stability to the entire battery structure.
