Introduction to battery adhesive

In the global primary battery and rechargeable battery industry, the common zinc-manganese battery developed most rapidly in the 1980s, and the alkaline zinc-manganese battery showed a strong growth trend in the 1990s because of its high cost performance advantage, both of which jointly accounted for more than 80% of the primary battery market. Li-ion batteries with high specific energy and long service life, although expensive, have become the main choice in the market of medical electronic equipment, smart cards, support power supplies and military electronic equipment, although the market is small (about 12%), it is indispensable. As the chemical power source with the widest application range and the largest consumption, the lead-acid battery industry has both opportunities and challenges. With the rapid rise of basic industries such as energy, transportation and communications and the implementation of the "Tenth Five-Year Plan", the demand for lead-acid batteries has increased by 15% to 40% annually. In 2001, the national production of lead-acid batteries reached more than 20 million kW-h. However, other batteries with high specific energy, such as nickel metal hydride (MH-Ni) batteries, lithium-ion batteries and high-efficiency, low-cost and pollution-free solar cells, will become strong competitors for lead-acid batteries. As a kind of raw material in battery industry, adhesive has a great impact on battery performance and product quality, although its amount is small.

Parameter

What is OPzV battery?

D King OPzV battery, also named GFMJ battery
The positive plate adopts tubular polar plate, so it also named tubular battery.
The nominal voltage is 2V, the standard capacity normally 200ah, 250ah, 300ah, 350ah, 420ah, 490ah, 600ah, 800ah, 1000ah, 1200ah, 1500ah, 2000ah, 2500ah, 3000ah. Also customized capacity are produced for different applications.

Structural characteristics of D King OPzV battery:
1. Electrolyte:
Made of German fumed silica, the electrolyte in the finished battery is in gel state and does not flow, so there is no leakage and electrolyte stratification.

2. Polar plate:
The positive plate adopts tubular polar plate, which can effectively prevent the falling off of living substances. The positive plate skeleton is formed by multi alloy die casting, with good corrosion resistance and long service life. The negative plate is a paste type plate with a special grid structure design, which improves the utilization rate of living materials and the large current discharge capacity, and has strong charging acceptance capacity.

3. Battery shell
Made of ABS material, corrosion resistant, high strength, beautiful appearance, high sealing reliability with the cover, no potential leakage risk.

4. Safety valve
With special safety valve structure and proper opening and closing valve pressure, water loss can be reduced, and expansion, cracking and electrolyte drying of battery shell can be avoided.

5. Diaphragm
The special microporous PVC-SiO2 diaphragm imported from Europe is used, with large porosity and low resistance.

6. Terminal
Embedded copper core lead base pole has greater current carrying capacity and corrosion resistance.

Key advantages compare to normal gel battery:
1. Long life time, floating charge design life of 20 years, stable capacity and low decay rate during normal floating charge use.
2. Better cycle performance and deep discharge recovery.
3. It is more capable of working at high temperature and can work normally at - 20 ℃ - 50 ℃.
