Embodiment 1
[0020] A positive electrode active material formula is used to prepare a positive electrode plate. The formula is 80% lead powder, 5% lead tetroxide, Na 2 O 2 5%, CMC 2%, deionized water 3%, sulfuric acid (specific gravity 1.05 g / cm 3 ) 5%; when making the paste, first mix and stir the lead powder, lead tetroxide and sodium peroxide powder for 3 minutes, then add CMC and stir for 5 minutes, then add deionized water, stir for 8 minutes, and finally add 1.05 g / cm 3 The positive electrode plate can be coated by stirring the sulfuric acid for 10 minutes; the coated electrode plate can be dried in a 60 ℃ drying room for 4-6 hours before entering the assembly and battery formation process. The rest of the process can completely use the current valve-controlled sealing lead The production process of acid batteries.
[0021] The prepared plates are assembled into a 12V12Ah valve-regulated sealed lead-acid battery for electric bicycles for performance testing. The 6A discharge time is 13...
Embodiment 2
[0023] A positive electrode active material formula is used to prepare the positive electrode plate. The formula is 70% lead powder, 8% lead tetroxide, Na 2 O 2 8%, CMC 3%, deionized water 5%, sulfuric acid (specific gravity 1.05 g / cm 3 ) 6%; when making the paste, first mix and stir the lead powder, lead tetroxide and sodium peroxide powder for 5 minutes, then add CMC and stir for 8 minutes, then add deionized water, stir for 10 minutes, and finally add 1.05 g / cm 3 The positive electrode plate can be coated by stirring the sulfuric acid for 15 minutes; the coated electrode plate can be dried in a 60 ℃ drying room for 4-6 hours to enter the assembly and battery formation process. The rest of the process can completely use the current valve-controlled sealing lead The production process of acid batteries.
Embodiment 3
[0025] A positive electrode active material formula is used to prepare a positive electrode plate. The formula is 75% lead powder, 5% lead tetroxide, Na 2 O 2 5%, CMC 2%, deionized water 5%, sulfuric acid (specific gravity 1.05 g / cm 3 ) 8%; when making the paste, first mix and stir the lead powder, lead tetroxide and sodium peroxide powder for 4 minutes, then add CMC and stir for 6 minutes, then add deionized water, stir for 9 minutes, and finally add 1.05 g / cm 3 The positive electrode plate can be coated by stirring the sulfuric acid for 12 minutes; the coated electrode plate can be dried in a 60 ℃ drying room for 4-6 hours before entering the assembly and battery formation process. The rest of the process can completely use the current valve-controlled sealing lead The production process of acid batteries.
