Embodiment 1
[0020] Embodiment 1: Take the commonly used 2V500Ah battery as an example:
[0021] 1. Plate production:
[0022] Positive grid 7 is cast by using high-tin and low-calcium lead alloy (the content of tin is 2.0%, the content of calcium is 0.08%, and the balance is lead);
[0023] In addition to lead powder, 0.8% polyester fiber, 8.0% sulfuric acid (1.4g / ml), 13% deionized water, 0.5% graphite, 0.08% Bi 2 o 3 , 0.1% Sb 2 o 3 , 0.08% SnSO 4 , 0.6% polyaniline, 0.6% 4Pb·PbSO 4 . Lead powder, polyester fiber, graphite, Bi 2 o 3 , Sb 2 o 3 , SnSO 4 , polyaniline, 4Pb·PbSO 4 Perform dry mixing first, then add deionized water in the prescribed amount for wet mixing, and then slowly add the sulfuric acid solution in the prescribed amount after wet mixing, and fully stir to form the positive lead paste 6, which is filled and coated on the positive grid 7, and cured After drying, a positive plate is formed;
[0024] The negative grid 5 is cast by ordinary lead-calcium allo...
Embodiment 2
[0029] Embodiment two: prepare 2V500Ah battery by the method for embodiment one, difference is:
[0030] The tin content of the positive grid is 1.2%, and the calcium content is 0.04%;
[0031] In addition to lead powder, 1.0% polyester fiber, 10% sulfuric acid (1.4g / ml), 11% deionized water, 0.2% graphite, 0.04% Bi 2 o 3 , 0.05% Sb 2 o 3 , 0.04% SnSO 4 , 0.2% polyaniline, 0.2% 4Pb·PbSO 4 ;
[0032] In the negative electrode active material, except lead powder, also add polyester fiber relative to lead powder quality 1.0%, 11% sulfuric acid (1.4g / ml), 11% deionized water, 0.4% lignin, 0.4% Humic acid, 0.2% acetylene black, 0.1% indulin, 0.1% anisaldehyde;
[0033] SiO 2 The weight percentage relative to the electrolyte is 0.5%.
[0034] The battery prepared in the above example was subjected to a high-temperature accelerated float charge life test. The test procedure was: place the battery in an environment of 60±2°C, charge it continuously for 30 days at a float volt...
