The main composition in spent lead-acid batteries are lead alloy grids, lead pastes, waste acid and plastics. Lead paste is made of various lead compounds, including PbO (~9%), PbO 2 (~28%), PbSO 4 (~60%) and a little lead (~3%) (Zhu et al., 2012). Among them, the recovery of lead paste is the key and difficult point.

Red lead: understanding red lead in lead−acid batteries
Red lead (Pb 3 O 4), also known as minimum, trileadtetroxide or lead orthoplumbate, is normally a fine, dry, brilliant red colored solid usually used in the form of a powder can also be wetted and agglomerated into pellets. In contrast to other lead oxides, the lead atoms in red lead occur in two different oxidation states, i.e. Pb(II) and Pb(IV).
