Embodiment 1
[0027] Embodiment 1, 1. getting proportion is that 99 weight parts of sulfuric acid solution first of 1.28 mixes with 1 weight part cerium ammonium nitrate solution and prepares sulfuric acid cerium ammonium nitrate mixed solution,
[0028] ② Take the sulfuric acid solution B with a specific gravity of 1.51 and the sodium silicate solution with a specific gravity of 1.07 and mix them according to the volume ratio of 1:1 to prepare sodium sulfate silicate mixed solution.
[0029] ③First add 1 / 4 volume of cerium nitrate ammonium sulfuric acid mixture into the battery and shake it up and down until the mixture is fully absorbed by the plates, then fill the battery with sodium sulfate silicate mixture.
Embodiment 2
[0030] Embodiment 2, 1. getting specific gravity is that 99.2 weight parts of sulfuric acid solution first 99.2 parts by weight of 1.29 are mixed with 0.8 parts by weight of ceric ammonium nitrate solution to prepare sulfuric acid ceric ammonium nitrate mixed solution,
[0031] ② Mix sulfuric acid solution B with a specific gravity of 1.53 and sodium silicate solution with a specific gravity of 1.05 according to a volume ratio of 1:1 to prepare a sodium sulfate silicate mixture.
[0032] ③First add 1 / 4 volume of cerium nitrate ammonium sulfuric acid mixture into the battery and shake it up and down until the mixture is fully absorbed by the plates, then fill the battery with sodium sulfate silicate mixture.
Embodiment 3
[0033] Embodiment 3, 1. getting specific gravity is that 99.5 weight parts of sulfuric acid solution first 99.5 parts by weight of 1.30 are mixed with 0.6 parts by weight of ceric ammonium nitrate solution to prepare sulfuric acid ceric ammonium nitrate mixed solution,
[0034] ② Mix sulfuric acid solution B with a specific gravity of 1.55 and sodium silicate solution with a specific gravity of 1.03 in a volume ratio of 1:1 to prepare a sodium sulfate silicate mixture.
[0035] ③First add 1 / 4 volume of cerium nitrate ammonium sulfuric acid mixture into the battery and shake it up and down until the mixture is fully absorbed by the plates, then fill the battery with sodium sulfate silicate mixture.
[0036] The percentage by weight of each raw material of the battery electrolyte containing rare earth prepared according to the above ratio is:
[0037] Sulfuric acid (H 2 SO 4 ) 34%-37%
[0038] Sodium silicate (as SiO 2 Total) 2.0%-3.5%
[0039] Cerium ammonium nitrate Ce(NH...
