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.
