Abstract
A elongated valve control hermetic sealing lead-acid storage battery lead grease formulation and solidification process, wherein the percentages by weight of each ingredient in the lead grease formula are, lead powder 65-80%, red lead 8%-20%, short fibers 0.07%- 0.15%, sulfuric acid 5%- 10%, water 5%- 10%, the high temperature and high moisture process is used for solidification, with a temperature of 70-85 degree C., and a moistness over 95%, the curing time is 20h - 30 h, the invention can guarantee both the initial capacity and the cycle life of the battery.
Description
Technical field
The present invention relates to a kind of prescription and curing process thereof of valve controlled sealed lead-acid accumulator anode diachylon, belong to the sealed lead acid storage battery technical field.
Background technology
The prescription of lead-acid accumulator anode diachylon and curing process adopt dual mode at present, and a kind of is the grittiness paste that a crust powder is made, and adopts high temperature and heavy wet solidification technology; Another kind is the sticky plaster that Daojin powder is made, and adopts low-temperature setting technology.There are following problem in these two kinds of prescriptions and curing process: the grittiness paste that (one) crust powder is made, and the employing high temperature curing process has extended cycle life but initial capacity is low; (2) sticky plaster made of Daojin powder adopts low-temperature setting technology, with preceding a kind of just in time opposite, and initial capacity height but cycle life is short.Analyze theoretically following 2 reasons are arranged: (one) crust powder is spherical, and grittiness paste density is big, so porosity is low, the reaction table area is little, and the 4BS that adopts hot setting to generate is difficult for changing into active material, thereby causes initial capacity low; And Daojin powder in the form of sheets, and sticky plaster density is little, so the porosity height, the reaction table area is big, and the 3BS that generates with low-temperature setting easily changes into active material, thereby causes the initial capacity height; (2) 4BS that adopts hot setting to generate, has the formation network-like structure, prevent the function that active material comes off, and high temperature and heavy wet solidification easily makes grid and active material interface form fine and close corrosion layer, active material is combined with grid firmly, improve the charge acceptance of battery, thereby cause having extended cycle life; The 3BS that adopts low-temperature setting to generate can't form network-like structure, and active material comes off easily, and low-temperature setting is difficult for making grid and active material interface to form fine and close corrosion layer, it is insecure that active material is combined with grid, and the charge acceptance of battery is poor, thereby cause cycle life short.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art, provide a kind of initial capacity big, have extended cycle life, grid and the active material adhesion is good, charge acceptance is strong long and narrow type valve controlled sealed lead acid accumulator lead paste formula and curing process.
Technical scheme of the present invention is: lead paste formula is made up of lead powder, red lead, short fiber, sulfuric acid, water, and improvements are: new combination is that described lead powder is a Daojin lead powder, and used sulfuric acid density is 1.4g/cm
3, lead plaster is a grittiness paste, apparent gravity is 4.25～4.40g/cm
3, the percentage by weight of each composition is in the prescription: Daojin lead powder is 65%～80%; Red lead is 8%～20%; Short fiber is 0.07%～0.15%; Sulfuric acid is 5%～10%; Water is 5%～10%.
Above-mentioned Daojin lead powder oxidizability is 70%～80%, and water absorption rate is 100～130ml/Kg, Fe in the impurity content≤0.0005%, Cu≤0.001%.
The lead plaster curing process is to adopt hot and humid technology, and temperature is between 70 ℃～85 ℃, and humidity is more than 95%, and curing time is between 20 hours to 30 hours.
Adopt above technical scheme, Daojin powder in the form of sheets, the reaction table area is big, so the initial capacity height; The 4BS that adopts hot setting to generate, has the formation network-like structure, prevent the function that active material comes off, and hot setting easily makes grid and active material interface form fine and close corrosion layer, active material is combined with grid firmly, guarantee the anodal enough intensity that has, improve the charge acceptance of battery, thereby cause having extended cycle life.In a word, adopt Daojin powder and grittiness paste to carry out high temperature and heavy wet solidification, the initial capacity that can guarantee battery can guarantee the cycle life of battery again.
Embodiment
Adopt the wherein a kind of of above scheme, the percentage by weight of each composition is Daojin lead powder 72%, red lead 10%, short fiber 0.10%, sulfuric acid 8%, water 9.9% in the lead paste formula; Solidify and adopt hot and humid technology, humidity is 100%, and temperature is 80 ℃, and be 20 hours curing time.Experimentizing after making electrode assembling 2V300Ah battery, with the 30A constant-current discharge to the 1.80V/ monomer.The battery that adopts this programme to make was put 11 hours 45 minutes, and the battery that adopts a crust powder and grittiness paste hot setting to make was at present only put 10 hours 15 minutes, as can be seen, was made the battery that the initial capacity of battery makes than a crust powder by this programme and improved 12%.Carry out cycling life test again, test method is: earlier with 1.0I
10Be discharged to final voltage 1.80V/ monomer, with 2.35V/ monomer constant voltage 1.5I
10Current-limiting charge 10h is then with 2.25V/ monomer constant voltage 1.0I
10Current-limiting charge 24h is behind the static 1h, again with 1.0I
10Being discharged to final voltage 1.80V/ monomer, more than is a unit, continuous detecting to discharge capacity be lower than initial capacity 80% till.The battery cycle life that adopts this programme to make is 62 times, adopting Daojin powder and sticky plaster to carry out the battery cycle life that low-temperature setting makes only is 45 times, and visible this programme is made the battery that battery cycle life makes than Daojin powder and sticky plaster low-temperature setting and improved 14%.
