The change of the phase composition of lithium battery and paste processes
Lithium battery lead paste phase composition and lead powder, sulfuric acid, and the relationship between the temperature. And according to the procedure when making a lead youth to join: lead oxide, water, sulfuric acid solution. Water quickly in principle, with slow, acid and finish around 15 min, lithium battery and cream in 30 ~ 80 ℃, the temperature control for 40 - mixing time SOmin。 And after the paste, must carry on the process requirements of the relevant tests. Under 30 ℃ and creams, sulfuric acid content < 8%, the main form 3 bs, bs 3 increased with the increase of acid content. IBS acid content is about 8% when formed, IBS are formed when acid content of more than 8%. Lead in the green small rhombic PbO.
