Among the present invention, add antimony oxide and help producing no antimony effect, enhanced activity material and grid adhesion; Carbon fiber helps improving active material utilization; The content of deionized water increases to some extent, and the density of sulfuric acid decreases, and helps the uniformity that lead plaster mixes.Each component and content rationally, standard, can effectively improve the conductivity of active material, improve the recombination reaction ability of oxygen, suppress the battery dehydration, thereby improve battery charge ability to accept, big electric current discharge at starting performance and dark cycle life.
Embodiment
Further specify the present invention and beneficial effect thereof through embodiment below.
The positive electrode active materials component of example one, example two and content is (numeral is a mass percent in the table) as follows:
| ? | Free lead % | Lead oxide % | Brown lead oxide % | Carbon fiber % | Antimony oxide % | Polypropylene fiber % | Density 1.28g/cm 3Sulfuric acid % | Deionized water % |
| Example 1 | 14 | 38 | 31 | 1 | 2 | 0.2 | 5 | 8.8 |
| Example 2 | 10 | 41 | 29 | 0.5 | 1.4 | 0.1 | 8 | 10 |
Its preparation method is: free lead, lead oxide, brown lead oxide are mixed into lead powder; Under dry state, mixed 8 minutes with antimony oxide, carbon fiber, polypropylene fiber again, in 5 minutes, at the uniform velocity add deionized water while stirring, continue to stir 5 minutes; Add sulfuric acid again; Add the 10 minutes time of acid, continue to stir 10 minutes, process lead plaster.Control and cream temperature are 60～70 ℃ in the preparation process, and temperature control is 52～58 ℃ when going out the cream smear.
Process of the test of the present invention and effect are described below:
1, cell preparation
Example one said positive electrode active materials is made positive plate; Press the common process assembling and make the 6-GFM-100UPS uninterrupted power supply with 12 of lead-acid batteries; With the 10hr calculation of capacity, prepared cell positive electrode active materials dry weight is 13.0g/Ah, and the negative active core-shell material dry weight is 11.5g/Ah.With the sulfuric acid (having added 0.3% analytical pure sulfuric acid sodium) of 1.235g/ml (25 ℃) battery is annotated acid, change into to adopt and be internalized into three and fill two and put standard, after battery rolls off the production line, left standstill 72 hours, the pressure reduction 20mV that discharges by measure, terminal voltage 10mV carry out.From 12 samples, extract 6 and be made into 2 groups, carry out the cycle life test respectively, take out 3 again and carry out the charge acceptance test, remaining 3 are carried out permanent power test.48V100A type storage battery circulating inspector and permanent power discharge appearance that checkout equipment adopts Zhangjiagang Jin Fan Electrosource, Inc. to produce.
2, charge acceptance test
Extract 3 batteries in the sample battery,, put into 0 ℃ low temperature chamber 25h more respectively with 10A current discharge 5h; Taking-up is in 1min; With constant voltage 14.4V charging storage battery is charged, behind the 10min, record maximum charging current and be respectively 30A, 32A, 31A; Generally about 20A, the present invention has improved the charge acceptance of battery to the battery maximum charging current of prior art.
3, permanent power discharge test
From the sample battery, extract 3 batteries, respectively with the permanent power discharge of 200W to final pressure 10.5V, be respectively the discharge time of 3 batteries 35 fens; 36 minutes; 37 minutes, the battery discharge time of prior art had only about 25 minutes, and the present invention has improved permanent power discharge performance more than 40%.
4, cycling life test
With 2 Battery packs that prepare (3 every group), carry out the cycle life test respectively.The circulation standard is: constant voltage 56.4V, the current limliting 20A 16h that charges, leave standstill 2h after, till being discharged to the battery pack final voltage and being 43.2V with constant current 10A, be a circulation, when the discharge capacity of whole Battery pack is lower than 80% of rated capacity, end-of-life.
(1) capacity attenuation speed
Capacity was 100% of an initial capacity when battery pack 1 was circulated to the 20th time, and decay is not 95% of initial capacity when being circulated to 50 times, capacity attenuation 5%.
Capacity was 99% of an initial capacity when battery pack 2 was circulated to the 20th time, and basic not decay is 94% of initial capacity when being circulated to 50 times, capacity attenuation 6%.
When the battery of prior art is circulated to 20 times capacity attenuation 20%, this shows that capacity attenuation speed of the present invention obviously reduces, cycle performance is significantly improved.
(2) cycle life number of times
The discharge capacity that is circulated to whole Battery pack by the cycle life standard of above-mentioned formulation is lower than 80% o'clock of rated capacity, and the 1st group cycle-index is 210 times, and the 2nd group is 215 times.The battery cycle-index of prior art generally has only about 120 times.
Can explain from above-mentioned result of the test, adopt the battery charge ability to accept of the active material making of the present invention's example one, permanent power discharge ability, dark cycle life performance obviously to improve.
Adopt the battery of the active material making of the present invention's example two to carry out above-mentioned test, also obtain same effect.
