Embodiment
Further illustrate below in conjunction with instantiation, but the invention is not restricted to example below.
Example 1, each weight of material ratio: lead powder 750, antimonous oxide 2, bismuth oxide 0.5, stannous sulfate 1, magnesium sulfate 0.5, aluminum sulfate 0.5, zinc oxide 0.5, aquadag 2, fiber 1, red lead 250, dilute sulfuric acid 86(1.40g/ml), CMC1.5, silica 1 .5, pure water 110.
This apparent density of lead paste is about 4.4g/cm
3, the positive plate that the lead plaster adopting this to fill a prescription makes joins conventional anode plate, test loop performance in the following manner:
-12Afor5s-13Ato8V+0A*3min-6Ato10.5V+0A*3min+1.5A*14.7V*0.9A*16h
13A discharge into 8V phases-time be less than 32min be judged to be lost efficacy.Result is as follows:
| Cycle-index | Conventional batteries | Example 1 battery |
| 100 | <32min | 45min |
| 200 | --- | 41min |
| 300 | --- | 36min |
The lead plaster needle penetration of example 1 is suitable with conventional lead plaster, be 24 ~ 25, but cycle performance is significantly improved.Blemish in an otherwise perfect thing, after solidification is dry, dust is more; Lost efficacy after 345 circulations, battery dehydration 350g, anode plate grid corrosion is more obvious.
Applicant studies discovery, reduces red lead consumption, heightens CMC to increase lead plaster viscosity, can improve the dry rear more problem of dust of solidification; Adjustment reduces antimonous oxide and aquadag equal proportion, the corrosion of the anode plate grid of liberation of hydrogen dehydration may being caused too fast, reducing antimonous oxide ratio by a relatively large margin simultaneously, slightly heightening bismuth oxide ratio reducing it; Because of the reduction of aquadag, increase the deficiency that stannous sulfate supplements electric conductivity, both magnesium sulfate aluminum sulfate adjusts slightly, and the ratio heightening zinc oxide forms spinel structure with accelerating oxidation zinc together with aluminum sulfate, based on aforementioned embodiment 2.
Example 2, each weight of material ratio: lead powder 950, antimonous oxide 1.5, bismuth oxide 0.6, stannous sulfate 1.2, magnesium sulfate 0.4, aluminum sulfate 0.6, zinc oxide 2, aquadag 1.5, fiber 0.8, red lead 50, dilute sulfuric acid 90 (1.38g/ml), CMC3, silica 1 .5, pure water 108.
This apparent density of lead paste is about 4.3g/cm
3, the positive plate that the lead plaster adopting this to fill a prescription makes joins conventional anode plate, and by the testing standard that example 1 is same, result is as follows:
| Cycle-index | Conventional batteries | Example 2 battery |
| 100 | <32min | 44min |
| 200 | --- | 39min |
| 300 | --- | 34min |
Example 2 lead plaster is partially soft, and needle penetration 29 ~ 30, sticks together during full-filling, should reduce CMC ratio; Solidify dried pole plate and float powder minimizing, illustrate and reduce red lead ratio Be very effective; Example 2 battery and conventional batteries contrast and are also greatly improved.But deep-circulating performance is decayed, comparatively example 1 is fast, dead battery inefficacy dehydration 120g, have substantial degradation compared with the 350g of example 1, when dissected finds that grid corrosion is lighter, illustrate that the object reducing antimonous oxide reaches, but positive active material part is softened, circulate battery failure after 325 times, caused by possible antimonous oxide ratio is lower; First time electric discharge only has 43min many, and initial performance is lower, and possible aquadag ratio is not enough, needs to improve conductivity further; Consider spinelle proportioning, example 2 zinc oxide ratio is higher.Again example 3 is attempted based on aforementioned.
Example 3, each weight of material ratio: lead powder 950, antimonous oxide 1.8, bismuth oxide 0.5, stannous sulfate 1.5, magnesium sulfate 0.4, zinc oxide 1, aluminum sulfate 0.6, aquadag 3, fiber 1.5, red lead 50, dilute sulfuric acid 86 (1.40g/ml), CMC2, silica 1 .5, pure water 110.
This apparent density of lead paste is about 4.2g/cm
3, the positive plate that the lead plaster adopting this to fill a prescription makes joins conventional anode plate, and by the testing standard that example 1 is same, result is as follows:
| Cycle-index | Conventional batteries | Example 3 battery |
| 100 | <32min | 45min |
| 200 | --- | 45min |
| 300 | --- | >42min |
Example 3 comparison example 2, heighten antimonous oxide ratio, lead plaster is suppressed to soften, sulfuric acid with 1.40 is intended to highdensity acid and produces thick lead sulfate particle, improve lead plaster hardness, in like manner reducing CMC ratio is also for suitably heightening lead plaster hardness, the lead plaster needle penetration of example 3 is 26 ~ 27, there is not obvious adhesion in full-filling, increase stannous sulfate and aquadag ratio are intended to improve conductivity further, example 3 battery performance is better than example 1 and example 2 far away, 45min is many in first time electric discharge, capacity attenuation is the slowest, after deeper cavity 300 times, still have 42min many, the battery after more than 450 time that circulates just lost efficacy, dehydration 340g after losing efficacy, suitable with example 1, but consider example 3 cycle-index comparatively many more than 100 times of example 1 battery, its dehydrating speed also can accept.
Based on above-mentioned, after we think and add above-mentioned additive to lead plaster, performance has largely to be improved, but the adding proportion of these additives is also very large to performance impact difference.The present invention is not limited to the mode of above-mentioned concrete enforcement, and the engineering staff of the art can make multiple change accordingly, but any change identical with similar with the present invention is all encompassed in the scope of the claims in the present invention.
