Description

High energy storage lead acid accumulator lead paste formula and preparation method

Technical field

The present invention relates to the lead acid accumulator technical field, lead paste formula during the pole plate that is specifically related to a kind of electric boosted automobile-used lead acid accumulator is made and preparation method thereof.

Background technology

Lead-acid battery has had the history in 130 years, has dependable performance, and mature production technology is than Ni-MH battery and lithium battery low cost and other advantages.The present electric motor car overwhelming majority adopts the sealing-type lead-acid battery.The sealing-type lead-acid battery is that positive and negative pole plate interfolded is arranged in the battery case, isolates with insulating barrier between the positive and negative pole plate, and in electrolyte charged into battery case, the lead on electrolyte and the positive and negative pole plate carried out chemical reaction.When battery charge, the lead that becomes on the positive and negative two-plate of lead sulfate is discharged into the sulfuric acid composition that is fixed therein in the electrolyte, becomes lead and lead oxide respectively, and the sulfuric acid concentration in the electrolyte is constantly increased, and voltage rises, the savings energy; During discharge; Lead oxide in the positive plate and the lead on the negative plate and the sulfuric acid in the electrolyte react and become lead sulfate, and the sulfuric acid concentration in the electrolyte is constantly reduced, and voltage descends; Make energy reduce; Battery is externally exported energy, so the cycle charge-discharge of battery is the process that electric energy and chemical energy are constantly changed, finally realizes the storage and the release of energy.

Electric boosted automobile-used lead acid accumulator is the core component that is applied to the Moped Scooter field, and the performance of storage battery and quality are directly connected to the cruising of Moped Scooter, and the performance of lead acid accumulator and quality mainly receive the influence of lead paste formula.At present, the lead paste formula of domestic electric boosted automobile-used lead acid accumulator is different, directly uses the prescription of common valve-regulated lead-acid battery mostly, and the prescription of common valve control storage battery can't solve the anti-over-discharge property of storage battery and the problem of charge acceptance difference.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of the overcome over-discharge property of electric boosted automobile-used lead acid accumulator and the problem of charge acceptance difference, improves the high energy storage lead acid accumulator lead paste formula and the preparation method in its useful life.

Technical problem to be solved by this invention adopts following technical scheme to realize,

A kind of high energy storage lead acid accumulator lead paste formula is characterized in that: comprise anode diachylon prescription and cathode lead plaster prescription,

Described anode diachylon prescription is made up of following raw materials according by weight percentage:

All the other are lead powder;

Described negative plate lead paste formula is made up of following raw materials according by weight percentage:

All the other are lead powder.

The oxidizability of said lead powder is 72%～78%.

The method for preparing above-mentioned high energy storage lead acid accumulator lead plaster adds the rouge and powder in the above-mentioned anode diachylon prescription, aquadag, polyester staple fibers peacekeeping stannous sulfate in the full-automatic paste mixing machine, or the acetylene carbon black in the cathode lead plaster prescription, humic acid, barium sulfate, barium stearate, sodium lignosulfonate and polyester staple fiber is added in the full-automatic paste mixing machine; The limit is put the lead powder limit and is stirred, and has put to do behind the lead powder to stir 5～7min, and the stirring of deionization waterside is put on the limit then; Put the deionized water continued and stirred 5～6min, put dilute sulfuric acid then, added at 16～18min; The limit edged stirs, and configures the cooling system of fetching boiling water when temperature reaches 48 ℃, and temperature reaches 58 ℃ and opens air cooling system; Add sour process control lead plaster temperature at 45～63 ℃, add acid after, continue to stir 12～15min; Measure the lead plaster apparent density then, the anode diachylon apparent density requires 4.23～4.30g/cm3, and the cathode lead plaster apparent density requires 4.35～4.45g/cm3; After meeting the requirements, go out cream, and the temperature that goes out cream is less than 45 ℃.

Rouge and powder among the present invention in the positive plate lead paste formula can improve the charge efficiency of storage battery, improves the initial capacity of storage battery; Add stannous sulfate, can reduce the self discharge of battery, make pole plate be easy to the useful life of charging and improving storage battery.

Humic acid in the negative plate lead paste formula can significantly improve the charge acceptance of storage battery; Acetylene carbon black can improve the electric conductivity of active material, improves the porosity and the first ability of charging circle that improves storage battery of active material.

The invention has the beneficial effects as follows: the lead plaster of lead paste formula of the present invention and preparation method thereof preparation, process storage battery after, have very high initial capacity and cycle life, anti-over-discharge property and the first ability in charging circle are far above standard-required.
