DETA//daryflex "Yinshan" battery group has the most advanced hardware-full automation assembly line, and the most excellent software-internal training team. The marketing department and production department work closely together to promote the products to the forefront of the international power market.

2、 Product Introduction

DETA//dryflex "silver fir" dryflex VEG gel series is designed with colloidal electrolyte and tubular positive plate, and has the advantages of valve-controlled battery (maintenance-free) and open battery (floating charge/cycle service life), which is especially suitable for use with backup time of 1 to 20 hours.

DETA//dryflex "silver fir" dryflex VEG gel series is specially designed for the requirements of backup power system, providing battery solutions with high rate discharge, high energy density and high cost performance. Because it is not limited by the use environment or maintenance, the DETA//dryflex "silver fir" dryflex VEG gel series is applicable to the environment with large temperature difference and unstable power grid, or the renewable energy storage system in the state of long-term power loss.

III. (2) Structural characteristics

3.1. The pole pole is sealed by a rubber ring (root), epoxy resin (middle) and anti-corrosion gasket (top)

The triple sealing structure overcomes the phenomenon of damaging the sealing gasket when the pole slides outward due to grid proliferation during use, and allows the battery to be placed vertically and horizontally.

3.2. Pole terminal - containing M8 internal thread brass mandrel, the surface is polished by plasma technology, and then plated with tin and

Release the oxide film.

When discharging at high rate, reduce the heat loss caused by the impedance of the contact surface

The surface does not need to be coated with Vaseline, and can still work in a humid environment for a long time.

3.3. Safety air valve - high sensitivity one-way low pressure air valve, which can be operated for 40000 times. The opening pressure is 20kpa, the closing pressure is 5kpa, and the valve is equipped with explosion-proof air plug (ceramic filter).

Under normal charging conditions, prevent internal gas leakage and prevent the atmosphere from entering.

Under abnormal charging conditions, release excess gas to ensure safe operation.

The explosion-proof gas plug prevents the flame from entering and detonates the combustible gas (hydrogen) in the battery.

3.4. Positive electrode plate - heavy lead-tin multi-element alloy grid, which can slow down the corrosion and proliferation of electrode plate and improve deep discharge

After the recovery, the floating charge and cycle working life are extended.

3.5. Negative electrode plate - antimony-free lead-calcium alloy grid, which improves the hydrogen precipitation potential, and the gas recombination efficiency reaches 99%

above.

3.6. The battery shell is made of impact resistant, corrosion resistant and anti-aging flame retardant ABS plastic. Reinforcing plate on both sides of slot

The design and slot cover positions are preset with handles or slings.

The stiffener design improves the mechanical strength of the shell, and reserves space for the heat loss to pass through, limiting the expansion of the plate to both sides under high temperature or overcharge.

In addition, the outer material of the shell can be recycled to reduce environmental pollution and respond to environmental protection.

3.7 The colloid battery adopts special microporous PVC-SiO2 separator, with high porosity to help gas diffusion, improve gas combination efficiency, and reduce the internal resistance of the battery with low internal resistance to improve the high rate discharge efficiency.

3.8 Composite mechanism

Colloidal electrolyte is required to have thixotropy, which means that when the colloid is stationary, its state is like solid. However, when the colloid is touched, the state returns to liquid, and when it is still again, it will solidify again.

Generally, the electrolyte at the later stage of the battery charging process produces gas, resulting in water loss, and the reaction is as follows:

Total reaction: 2H2O → 2H2+O2

Colloidal electrolyte is a mixture of silica particles (SiO2) and a certain concentration of sulfuric acid solution in proportion, and the silica solution is bonded to form a large three-dimensional network, that is, the silica particles are connected to form bonds, and then the bonds are interlaced to form a fine porous structure.

The smaller pores absorb a large amount of electrolyte due to the strong capillary phenomenon; Larger pores form voids, forming a channel for oxygen diffusion. Oxygen generated from the positive electrode penetrates and diffuses to the negative electrode through the pores of the electrolyte, and is absorbed by the negative electrode to form lead oxide. Then react with sulfuric acid to form lead sulfate, forming oxygen cycle.

Therefore, the charging process basically does not lose water, and the reaction is as follows:

Positive pole: H2O → 1/2O2+2H++2e-

Negative pole: Pb+1/2O2 → PbO

PbO+H2SO4→PbSO4+H2O

PbSO4+2H++2e-→Pb+ H2SO4

Total reaction: 1/2O2+2H++2e - → H2O

3.9 Terminal voltage difference

The coagulation process of colloidal electrolyte is spontaneous (independent of external influence) and slow.

At the initial stage of use, the deviation of floating charge voltage balance is a common phenomenon due to the gas cycling of some batteries stopping at the rich liquid stage, which has nothing to do with the process or quality of the battery.

Electrolyte solidification → gas cycling → terminal voltage equalization

Rich solution (W) battery → electrolyte decomposition → high terminal voltage

Lean solution (D) battery → gas cycle combination → low terminal voltage

However, after a period of use, the electrolyte structure is gradually consistent and the terminal voltage is also balanced

2.25V+0.15V -0.12V within 6 months, i.e. 2.13V -- 2.40V

After 6 months, 2.25V+0.10V -0.08V is 2.17V -- 2.35V

Even if the voltage of individual battery terminals exceeds the above range, there will be no trend of expansion. It is recommended to continue to use and observe its changes.
