What is the difference between lead carbon battery and lead acid battery?

1, the depth of discharge

The depth of discharge is the extent to which discharge occurs during using. 100% depth refers to the release of full capacity. The life of lead-acid batteries is greatly affected by the depth of discharge. The focus of design considerations is deep cycle use, shallow cycle use or float charge. If the battery used in the shallow cycle is used for deep recycling, the lead-acid battery will quickly fail.

Because of the positive active material of lead dioxide itself in combination with each other not firm, discharge generated when lead sulfate, charging back as the lead dioxide, lead sulfate molar volume is larger than lead oxide, when the discharge volume expansion of active material. If one mole of lead oxide is converted into one mole of lead sulfate, the volume is increased by 95%. This repeated shrinkage and expansion causes the mutual bonding between the lead dioxide particles to gradually relax and easily fall off. If a mole only 20% of active material of lead dioxide discharge, the degree of the contraction and expansion is greatly reduced, the binding force damage variable is slow, so, the deeper the depth of discharge, the shorter its cycle life.

2, the degree of charging

Charging with a large number of gas evolution, then the impact of the positive plate active substances by gas, the impact will promote active material loss; In addition, the positive plate grid alloy also suffered serious anodic oxidation and corrosion, so the battery charging will make the application period shorten.

3, the influence of the temperature

Lead acid battery life extends with increasing temperature. Between 10 ℃ ~ 35 ℃, every increase 1 ℃, increase about 5 ~ 6 cycle, between 35 ℃ ~ 45 ℃, every increase 1 above 25 ℃ can prolong life cycle; Above 50 ℃ due to negative sulfide capacity loss reduces the longevity.

Battery life in a certain temperature range increases with temperature rise, because the capacity increases with temperature rise. If the discharge capacity does not change, the depth of discharge decreases as the temperature increases, and the solid life is prolonged.

4, the influence of the concentration of sulfuric acid

Acid density increase, is advantageous to the positive plate capacity, but increased the self-discharge of the battery, board gate corrosion is accelerated, also helped lead dioxide loose fall off, with the increase of storage battery used in the acid density, cycle life.

5, Effect of discharge current density

As the discharge current density increases, the life of the battery decreases because the positive electrode dioxide is loosely detached under conditions of high current density and high acid concentration.

Lead carbon battery and lead acid battery and what is the difference between lead carbon batteries

Lead carbon batteries is the innovation of the lead-acid battery technology, compared to the lead-acid battery has many advantages. Lead carbon battery has the following advantages: one is the fast charging, 8 times charging speed; Second, the discharge power increased 3 times; Three is circle life up to 6 times, charging circuit number up to 2000 times; Four is cost-effective, than lead-acid battery prices have improved, but the life of the recycled greatly improved; Five is the use of safe and stable, can be widely used in all kinds of new energy and energy efficiency. In addition, the lead carbon batteries also played a lead-acid battery than energy advantage, and have very good charge and discharge performance - 90 minutes to charge (lead-acid battery if such a charge, discharge, life less than 30 times). Moreover, due to the addition of carbon (graphene), the sulphation of the negative electrode is prevented, and a factor of battery failure is improved.

Lead carbon batteries have what advantage

Lead carbon is a new type of super battery, battery is a lead-acid battery and super capacitor combination: both played a super capacitor moment both the advantages of large capacity rechargeable also played a lead-acid battery than energy advantage, and have very good charge-discharge performance - 90 minutes to charge (lead-acid battery if such a charge, discharge, life less than 30 times).And because of the added carbon (graphene), to prevent the phenomenon of cathode sulphates and improved the battery failure of a factor in the past, more longer battery life. Lead carbon batteries are asymmetric super capacitors with lead-acid battery using mixtures in parallel combination of both, as a new type of super batteries, carbon batteries is to lead lead-acid battery and super capacitor, the fusion technology is a kind of capacitance characteristics and dual function with battery characteristics energy storage battery. So both played a super capacitor instantly work spontaneously and the advantages of large capacity rechargeable also made use of the advantages of lead-acid battery energy, an hour can be fully charged. Has a good charge and discharge performance. Carbon technology with the use of lead, lead the carbon battery performance is much better than the traditional lead-acid battery, can be applied to new energy vehicles, such as: hybrid and electric vehicles, electric bicycles, and other fields; It can also be used in new energy storage areas, such as wind power storage. Lead-carbon batteries have the same low price advantage and mature industrial manufacturing base as traditional lead-acid batteries, and have strong competitive advantages in various application fields.

The hybrid technology can quickly during vehicle acceleration and braking charge output and input, particularly suitable for micro hybrid "stop a start" system. Lead carbon batteries can improve the power of original lead-acid battery, prolong service life.

In addition, the lead carbon batteries also giving full play to the advantages of the lead-acid battery than energy, and have very good charge and discharge performance - 90 minutes to charge (lead-acid battery if such a charge, discharge, life less than 30 times).And because of the added carbon (graphene), to prevent the phenomenon of cathode sulphates and improved the battery failure of a factor.

1. Positive and negative lead paste adopts unique formula and optimized curing process. The positive active material has strong anti-softening ability, good deep cycle life and high utilization rate of active materials; negative electrode lead paste has strong anti-vulcanization ability, low capacity decay rate and good low-temperature starting performance.
