Using their new-found knowledge, the team then went about finding ways to reduce (or even stop) this process. Realizing that chemical conversions were the culprit, they simply figured out that the pace at which the manganese was being transformed could be reduced by upping the manganese concentration in the electrolyte before applying power. (Interestingly, this is not too dissimilar to the research on Lithium-air batteries that sees great improvements when their electrolyte mixes are altered to reduce electrode disintegration.)
So I'm wondering if increasing the lead ions in the FLA sulphuric acid electrolyte might reduce sulphation of the lead plates. It seems feasible then that some additive might help if added when the batteries are new.
