Composition and sealing principle of EAST lead-acid battery

Lead acid batteryIt consists of positive electrode, negative electrode, electrolyte, separator and battery cell5The main components. The positive active substance of lead acid battery is two lead oxidePbO2The negative active material is spongy leadPbThe electrolyte is dilute sulfuric acid, and the separator is made of superfine glass fiberAGMOr polyvinyl chloride (or PVC)PVCThe battery tank is made of engineering plasticsABSOr polypropylenePPCorrosion resistant materials.

prefix = "v" ns = "urn:schemas-microsoft-com:vml" A storage battery is a kind of DC power source which converts electric energy into chemical energy and stores it, and then converts chemical energy into electric energy when it is used. Charge discharge reaction principle of lead-acid battery:PbO22H2SO4Pb       2PbSO42 H2O

The sealed maintenance free principle of sealed maintenance lead acid battery (cathode absorption type) is as follows:

    At the end of charging and over charging, the electric energy is mainly used to decompose the water, and the positive electrode reaches the charging amount70%Oxygen begins to pass out and oxygen passes throughAGMThe separator channel reaches the negative pole, reacts with the spongy lead and sulfuric acid of the negative electrode, and generates water again:
            2PbTenO2Ten2H2SO4 = 2PbSO4+2H2O
    The reaction results in the partial discharge of the negative electrode in the discharge state, which inhibits the hydrogen release (negative electrode charge must be reached)90%Only the oxygen released from the positive electrode can produce the lead sponge of lead sulfate, and the amount of spongy lead can be generated by charging with the negative electrode. The two can reach a balance, and the water is basically not lost.

 

1.3Main material characteristics of EAST lean liquid valve controlled sealed lead acid battery

1  Battery case

Use new engineering plastics that do not contain any recycled materialsABSorPP),V0Flame retardant (optional), high strength, not easy to damage, good sealing, and there is no due to the plastic shell itself contains recycled materials impurities caused by self discharge.

2  Grid and paste

The corrosion resistant design of thick plate is made of raw materials1Electrolytic lead with less impurities, corrosion resistance and self dischargePb-Ca-SnAlloy (high tin anode grid expansion agent and antioxidant formula); special paste containing active material, high temperature curing4BSPaste technology, ensure cycle durability.

3Safety valve

Using thick wall design, three EPDM rubber material, durable acid resistance, long term weight loss is small, can ensure the safety valve opening and closing valve constant pressure, safe and reliable.

4Separator

Ultra fine glass fiber separator is adoptedAGMIt has excellent acid absorption property, and has hydrophobic fiber, and its natural oxygen cycle

The channel ensures that oxygen and hydrogen recombination efficiency exceeds that in the battery95%It is not easy to dehydrate.

5Electrolyte

Laboratory analytical purity (ARConcentration sulfuric acid and resistivity100ten thousandΩ·cmThe deionized water is sealed in an auto dilute acid system

The electrolyte with low density (slow corrosion) made in the system and adding three element special metal sulfate additive can prevent micro short circuit and early capacity decay.

6Output terminal

The copper core silver plating embedded cylinder terminal is used to change the pollution of the output connection of the lead terminal and the copper terminal is not deformed,

1.4Technical performance characteristics of EAST lean liquid valve controlled sealed lead acid battery

1) good safety performance

The electrolyte in the battery is absorbed by the polar plate and superfine glass fiber, and there is no free flowing electrolyte in the battery. There is no electrolyte leakage under normal use,Side90Degree installation can also be used normally.

Valve controlled sealed structure, when the gas pressure in the battery is occasionally high, can automatically open through the safety valve, release pressure, to ensure safety, the internal combustion of flammable gas accumulation is less, can not reach the explosion concentration, excellent explosion proof performance.

2Maintenance free performance

The sealing efficiency of the gas seal is higher than that of the cathodic absorption type seal95%Under normal conditions, the water loss is very little, and the battery does not need regular fluid maintenance.

3Green environmental protection

No mist under normal charging, no pollution, no corrosion of equipment room environment.

4Self discharge is small

High gas evolution potential is adoptedPb-Ca-SnAlloy in20Place in the dry environment for half a year without throwing electricity

Into normal use.

Tight assembly process, internal resistance is small, can be carried out3Discharge discharge with double capacity3Minutes or6Discharge discharge with double capacity5Seconds, the battery has no exception.

7Long life

Due to the use of high purity raw materials and long life formula, battery consistency control process, in20In the environment of temperature,NP

Series battery life of up to normal float design710(year38AhAbove),GMSeries battery life of up to normal float design1215Year.

8The battery pack has good consistency

Regardless of the cost, each battery in the battery pack has a relatively uniform characteristic to ensure long term performance after being put into use

The discharge uniformity and consistency does not appear to float, the individual behind the battery and drag down the whole group battery.

(1) control the weight and thickness of the grid and the paste quantity from the source;

(2) weighing and grading of plates before assembly≥38AhA battery) to ensure the relative consistency of the amount of active substance in each monomer;

(3) quantitative accurate acid injection, four charging and three discharging system, equalization of battery performance;

Before discharging, the battery is discharged, and the capacity and open circuit voltage are matched once;

≥100AhThe stationary period of the battery before shipment is detected715DayTime trialWhen it is out of the warehouse, again100%Inspection can effectively detect the suspicious batteries which are difficult to detect when the line is out of order;

The library is based on open circuit voltage and internal resistance of battery was two times with the group.

2.2Don't make the battery discharge voltage lower than the prescribed value, over discharge will greatly shorten the battery life, serious when will cause the battery can not be used again.

2.3Don't store after discharge. Please charge immediately. The storage time should not exceed the maximum4It is difficult to recharge the battery after a long time, otherwise the battery can not be used.

2.4The maximum permissible discharge current should be controlled in the following range:

discharge current I≤1C10AThe discharge voltage of the battery monomer during intermittent discharge is equal to that of the battery1.90V);

discharge current I=3C10ADischarge time T≤3min

discharge current I=6C10ADischarge time T≤10s

  Long term high current (>1C10The discharge will have an adverse effect on the battery life.

2.5In order to ensure the battery life, each discharge depth can not be too large, the discharge capacity is best not to exceed80%. Especially in areas where electricity is frequently used, the battery after discharge should have surplus capacity to prevent damage to the battery due to long-term deep discharge.
