2, the working principle of lead battery

The anode lead in the accumulator (PbO2) and cathode (Pb) immersed into the electrolyte (sulfuric acid), between the two poles of 2V producing power, which is based on the principle of lead-acid battery, charge and discharge through the Yin and Yang, electrode and electrolyte occurs following changes:

(anode) (electrolyte) (cathode)

PbO2 + 2H2SO4 + Pb + 2H2O + PbSO4 I PbSO4 (discharge reaction)

(lead peroxide) (sulfuric acid) (spongy lead)

(anode) (electrolyte) (cathode)

PbSO4 + 2H2O + PbSO4 + 2H2SO4 + Pb I PbO2 (charge response)

(lead sulfate) (water) (lead sulfate)

3, lead acid battery main technical process characteristics

3.1 the battery uses the tight fitting, effectively prevents the active material to fall off. Prolong the service life of the battery.

3.2 efficient internal gas recombination, sealed reaction efficiency can reach above 98%. Very little water loss. There is no need to add electrolyte or ionic water during the whole life.

3.3 grid using a special lead calcium tin alloy, more resistant to corrosion, good charging capacity. Self discharge small. The battery storage performance and use performance is better.

3.4 the use of safety and reliability of the exhaust valve. Use more secure and reliable. To avoid the explosion hazards caused by sparks.

Reinforced structure 3.5 science, greatly reduce the internal resistance of the battery. The current distribution is more uniform. Discharge performance is better.

3.6 using multi-layer labyrinth sealing technology to ensure that the battery does not have leakage. Without bulging phenomenon.

3.7 using accurate distribution and control mode, the battery and the battery, the consistency between the battery group and the polar group is more superior.

3.8 special electrolyte additives to prevent battery lead dendrite short circuit and storage passivation.

3.9 the special internal resistance, voltage and battery capacity matching equipment, battery balance is excellent, the difference is less than or equal to 20mV open circuit voltage.

4, lead acid battery superiority

Very good charge and discharge property

After discharging to charge the strong resistance in continuous 21 days after discharge, the battery capacity recovery rate of more than 99%.

Long service life.

Japan advanced technology formula and process design, good service life.

Safe and reliable performance.

The special structure of the electro hydraulic mode, the exhaust valve of fluorine rubber, quantitative and effective irrigation of acid, as well as the high sealing performance. There is no leakage of the battery. Green pollution-free, safe use no worries.

Very good environmental adaptability, high and low temperature resistant ability

To adapt to the -30 C ~ 55 degrees Celsius in the environment, in addition to the reverse button, can be installed in any direction, without space restrictions.
