In view of these facts, any attempts to improve the conductivity of the negative active mass by the addition of graphite (a far less conductor than lead) would obviously have no sense.Electrode processes in lead-acid batteries have traditionally been discussed in terms of the dissolution–precipitation mechanism [10], [11], [12]. This is well ...
Phosphoric acid The addition of phosphoric acid to the electrolyte of lead/acid batteries has been practised since the 1920s [59]. The main motivations were reduction of sulfation (espe- cially in the deep-discharge state) and extension of cycle life by reduced shedding of positive active material.
Lead sulfation severely shortens the cycling life of lead-acid battery under high-rate partial-state-of-charge (HRPSoC) operation.
