. The partially hydrophobic character of synthetic separators has been overcome by organic
surfactants. Other organic compounds have been found to improve further the stability of separators against oxidation. Special organic molecules,
namely aldehydes and ketones, have been identified to retard, or even suppress, the adverse effects of metals such as antimony, and thus prolong
the cycle-life of traction batteries in heavy-duty applications or reduce water loss from automotive batteries. Knowledge about these interactions
has opened ways to improve separators.
