What is the lead-acid battery sulfation causes and hazards?

After the formation of lead sulfate high activity over a period of time, if there is no timely charge within this period of time, or charging is not complete, so that it does not translate into timely positive electrode active material, will again lead sulfate crystallization temperature is low, the crystalline precipitate of lead sulfate, this was repeated again and again, increasing the crystalline particles become poor conductivity, it is difficult to dissolve, when charging is difficult to recover lead sulfate crystals, known as irreversible salinization (manual refer to such alleged Electric Tricycle salinization salinization). There are many, such as an electrode grid corrosion fatal, severe deformation of the grid electrode, the electrode active material falling off, the battery internal short circuit or battery failure CAUSE Electric folding Bikes physicochemical, however, statistics show that battery failure majority are by the electrode active material caused irreversible sulfation.
