Detailed Product Description

Technical brief of the lead crystal battery products
1. lead crystal battery "(short for" lead crystal accumulator battery ") is on the basis of in-depth study of features and defects for lead-acid batteries and gel batteries, to self- made SiO2 composite electrolyte instead of vitriolic solution, using the sole advanced technology and engineering.

Lead crystal battery applicates its own invention patented technology and develop

the composite electrolyte technology, using a special formula, and completely replace the traditional solution of sulfuric acid, so that the product structure has undergone great change. During the charging, when the composite electrolyte of the electrolytic salt of the same pole, the role of epigenetic became crystalline active material of the plate can be fixed, and the exchange of ions leaving the channel to effectively overcome the plate sulfation, active the ills of material loss and dehydration, forming a good low temperature resistance and resistance to charge and discharge, and exponentially increase the life of the product.
GFMJ lead crystal battery products widely be used in such as transportation, energy, electricity, communications design and manufacture of energy storage backup battery.

2.1 The structural features
 (1) special electrolyte composition
Using a unique compounding technology that enables a variety of inorganic salts and organic synergy, optimize the performance of the reaction between the electrolyte and the electrode active material, to avoid the active substance into the salt off and prolong life. Several charge and discharge cycles, the crystalline state electrolyte, battery-free electrolyte, the battery can be a variety of orientation of the installation, eliminating the leakage of dangerous, improve safety performance.
 (2) the unique process
Matching in the polar group, welding, plus liquid and charge-discharge production process, production technology, the battery electrolyte is more uniform, better performance, efficiency improved.
2.2 The performance characteristics
(1) The long service life. Special grid structure made ​​of corrosion-resistant alloy, and unique national invention patents - high-energy silicon composite electrolyte technology, long-term float is not easy to produce sulfide, effective capacity can be quickly restored after the use of recharge. Than lead-acid battery life to extend more than doubled.
(2) the depth of discharge. Discharged to 0V, continue charging to resume full rated capacity.
(3) high discharge rate. 10C (A) discharge 5S, battery appearance without exception.
(4) the charge acceptance. Charge acceptance for 2I10.
(5) consistency: group capacity deviation of ≤ 3%, the open differential pressure ≤ 20mV / single cell.
(6) tolerance to low temperature performance. The normal working temperature range: -40 ℃ - +65 ℃.
(7), good environmental performance. Mist leakage, use and transport with higher safety and environmental protection, identified as "non-dangerous goods by the Chemical Registration Center of the State Production Safety Supervision Administration.

2、 Work principle

Main chemical reaction during discharge：

discharge

PbO₂  + 2H₂SO₄  +  Pb             PbSO₄  +  H₂O  +  PbSO₄

Discharge cathode active material and negative electrode active material and electrolyte of sulfuric acid the reaction of lead sulfate and water, so the acid concentration in the electrolyte to continuously reduce and vice versa during charging into positive and negative active material of lead sulfate internal sulfatereleased into the electrolyte ingredients, at the same time the positive and negative lead sulphate gradually turned into lead dioxide and spongy metallic lead, increasing the acid concentration in the electrolyte.
Ordinary lead-acid battery charging late or end-of-charge pre-charge current used for electrolysis electrolyte in the water, so that the water decomposition to produce oxygen on the cathode, anode to produce hydrogen gas in the low recombination efficiency from the battery a large number of internal escape, leaving the electrolyte within the battery reduced, resulting in dehydration, affect battery life, lead crystal battery using the composite electrolyte and proprietary grid alloy composition, in addition to the chemical reaction at the same time, the electrolytic liquid internal variety of additives are also involved in the reaction, inhibition of hydrogen, oxygen and a lot of precipitation, greatly improving the recombination efficiency of the battery, reducing battery in charge of post-dehydration phenomenon, and in the discharge of lead sulfate can completely restore the active substances, thus extending lead crystal battery life.
Lead crystal battery partitions using the very group that the AGM separator, has good electrical conductivity, heat and acid resistance, the role of the crystalline compound electrolyte can effectively protect the plate active material is easy to fall off, but also absorb and maintain the electrolyte, the electrolyte is absorbed in the plates and separators, so the battery at work from all directions.
