Embodiment 1
[0026] In this embodiment, the positive lead paste composition of internalized battery is made of the following raw materials in parts by weight: 1000 parts of lead powder, 1 part of fiber, 0.75 part of phosphoric acid, 1.5 parts of antimony trioxide, 1 part of zinc oxide, and 1 part of aluminum sesquioxide. 0.6 parts of ammonium bicarbonate, 0.4 parts of cerium hydroxide, 1.1 parts of tin oxide, 120 parts of water, and 85 parts of dilute sulfuric acid.
[0027] The density of dilute sulfuric acid is 1.40 g / cm 3 ; The apparent density of the lead paste composition is 4.4 g / cm 3 .
[0028] Table 1 is a comparison of the technical indicators of the electric vehicle lead-acid battery made of the lead paste of this embodiment (taking 6DZM12 battery as an example). The results show that: the conventional electric bicycle battery can be deeply discharged for 300 cycles, while the lead Batteries made of paste can be improved to 350 times.

[0032] The density of dilute sulfuric acid is 1.45 g / cm 3 ; The apparent density of the lead paste composition is 4.2 g / cm 3 .
Embodiment 3
[0034] In this embodiment, the positive lead paste composition of the internalized battery is made of the following raw materials in parts by weight: 1010 parts of lead powder, 0.5 part of fiber, 1 part of phosphoric acid, 1 part of antimony trioxide, 1.2 parts of zinc oxide, and 0.5 part of aluminum sesquioxide. 0.8 parts of ammonium bicarbonate, 0.3 parts of cerium hydroxide, 1.5 parts of tin oxide, 110 parts of water, and 90 parts of dilute sulfuric acid.
[0035] The density of dilute sulfuric acid is 1.35 g / cm 3 ; The apparent density of the lead paste composition is 4.6 g / cm 3 .
