Abstract
The invention relates to an anode of a lead acid storage battery, in particular to a lead plaster for an anode of a lead acid battery and a preparation method thereof. The lead plaster comprises the following components by weight: 100 portions of lead powder, 7 to 13 portions of 1.35g/cm<3> sulfuric acid, 8 to 12 portions of deionized water, 3 to 7 portions of red leads, 6 to 10 portions of six percent of PTFE emulsion and 2 portions of bismuth oxide 0.08-0 anode. Due to the addition of the red leads, the invention ensures that the pressure of a groove is lower when an unformed plate is formed, reduces the forming power consumption, and improves the contents of the lead dioxide of the plate. Due to the addition of PTFE, bismuth oxide and other components, the capacity and the service life of the battery are ensured to be improved.
Description
Technical field
The present invention relates to a kind of lead acid battery positive electrode, particularly a kind of lead-acid accumulator anode diachylon and preparation method thereof.
Background technology
Road high along with oil price, this discharging of electric motor car is few, and the walking-replacing tool of saving energy all develops rapidly in various places.And the development experience in electric motor car market shows, desires to obtain popularizing of electric motor car maximum magnitude, and people are concerned about the most remains its power section-chemical power source.Although the chemical power source that some are novel, include developmental research in succession in as Ni-H cell, lithium ion battery and fuel cell, but from the recent period, in multiple alternative chemical power source, the valve-controlled sealed lead-acid battery still with the performance of the best, price than and mature technique advantage and become the supporting first-selected power supply of present electric motor car.
Yet it is lower that lead acid accumulator also exists specific energy at present, the weakness that cycle life is too short, and this has greatly limited electric bicycle applying on market.A large amount of studies show that, is limited by positive pole the useful life of lead acid accumulator.And, on positive plate, often there is following problem along with the use of battery:
(1) product PbSO
4Bad conductivity, hindered inner active material and continued to participate in electrode reaction;
(2) the inner preferential PbSO that forms of electrode surface
4Because of its molal volume increases the duct of having stopped up between the active material, hindered the conduction of ion in the hole;
(3) disintegration of active material gel one network configuration makes active material soften prematurely, come off, thus premature loss battery initial capacity and shortened useful life of battery.
Summary of the invention
The objective of the invention is to propose a kind of lead-acid accumulator anode diachylon and preparation method thereof, mainly solve above-mentioned existing in prior technology technical problem.
For achieving the above object, technical scheme of the present invention is:
A kind of lead-acid accumulator anode diachylon is characterized in that being made up of following composition according to parts by weight:
100 parts in lead powder;
1.35g/cm

Described lead-acid accumulator anode diachylon, the oxidizability that it is characterized in that described lead powder is 73-78%.
A kind of preparation is the method for lead-acid accumulator anode diachylon as mentioned above, it is characterized in that it comprises the steps:
A puts into the cream machine that closes of heat exchanger with lead powder, adds red lead simultaneously, bismuth oxide is done and stirred 5～15 minutes;
B drenches into deionized water when stirring, and stirs 15～25 minutes again;
C adding the PTFE emulsion, stirs then;
D adds 1.35g/cm by spray
3Sulfuric acid, about 15～25 minutes of time remaining, and by heat exchanger control lead plaster temperature at 55～65 ℃;
E continues stirring and takes the dish out of the pot after 5～10 minutes.
By technique scheme, the present invention has following advantage:
1, the present invention has been owing to added red lead, makes green plate press lowlyer changing into time slot, reduces changing into power consumption, improves the brown lead oxide content of pole plate.
2, the present invention gets a promotion the capacity of battery and life-span owing to add compositions such as PTFE and bismuth oxide.Wherein, PTFE is an emulsion, and PTFE content is 6%, add can improve greatly after this material active material adhesion, the problem soft for battery life later stage active material can have good solution.
