Sulfation happens inside Lead–acid batteries when the electrolyte starts to break down. As the sulphuric acid (electrolyte) splits up, sulfur ions become free forming crystals. These sulfur ion crystals then stick to the lead plates of the battery, thus forming lead sulfate crystals. With time the crystals grow in size and become hard, covering …

This paper reports a new method of direct recovery of highly pure lead oxide (PbO) from waste lead pastes and lead grids of spent lead–acid batteries via catalytic conversion, desulfurization, and recrystallization processes in sequence.
Sulfation is a natural chemical process that occurs when lead sulfate crystals build up on the surface of a lead-acid battery''s electrodes during use. This buildup happens because the chemical reactions that produce electricity in the battery also produce lead sulfate crystals, which can accumulate over time.
