Lead-carbon battery is a kind of capacitive lead-acid battery, which is a technology evolved from the traditional lead-acid battery. It adds activated carbon to the negative electrode of the lead-acid battery, which can significantly improve the life of the lead-acid battery.

Lead-carbon battery is a new type of super battery, which combines lead acid battery and supercapacitor: it not only gives play to the advantages of instant large-capacity charging of supercapacitor, but also gives play to the advantages of specific energy of lead acid battery, and has very good charge-discharge performance - it can be fully charged in 90 minutes (if the lead acid battery is charged and discharged in this way, its life is less than 30 times). In addition, the addition of carbon (graphene) prevented the sulfation of the negative electrode, improved a factor of battery failure in the past, and extended the battery life.

Lead carbon battery for energy storage has high cost performance and cycle life of more than 3000 times

In the field of energy storage, lead-carbon battery has the advantage of cost-effective in the short term compared with lithium battery. At present, the lead-carbon battery used by the company for energy storage can reach a cycle life of more than 3000 times, with high cost performance and high promotion value. The promotion speed mainly depends on the domestic business operation mode.

Will lead acid batteries be completely replaced by lead carbon batteries in the future

Lead-carbon battery has the following advantages: First, it can charge quickly and increase the charging speed by 8 times; Second, the discharge power has been increased by three times; Third, the cycle life has been increased to 6 times, and the number of cycle charging has reached 2000 times; Fourth, it has a high performance-price ratio, which is higher than the price of lead-acid battery, but its cycle life is greatly improved; Fifthly, it is safe and stable, and can be widely used in various new energy and energy conservation fields 7] In addition, lead-carbon batteries also give full play to the specific energy advantage of lead-acid batteries, and have very good charge-discharge performance - they can be fully charged in 90 minutes (if the lead-acid batteries are charged and discharged in this way, the service life is less than 30 times). Moreover, the addition of carbon (graphene) prevented the sulfation of the negative electrode and improved a factor of battery failure.

The above is theoretical data, but now some companies have begun to produce lead-carbon batteries, which are indeed superior to ordinary lead-acid batteries in all aspects.

Discharge power and life are two important indicators of electric vehicles. Lead-carbon batteries are more suitable for low-speed electric vehicles than lead-acid batteries. As for high-speed and high-endurance electric vehicles, it is the world of lithium batteries.

For reference, the lead-carbon battery of Libang electric vehicle on the market is indeed better than the ordinary lead-acid battery.

Nowadays, more and more lithium-battery pure electric vehicles are produced in traditional automobile factories, and the price has reached the range of 40000 to 50000. Low-speed electric vehicles include lithium batteries and lead-acid batteries. Low-speed electric vehicles with lithium batteries may occupy the range of 30000 to 40000, while lead-acid batteries only have the range of 20000 to 30000.

But now the lead-acid battery has a short life and has no advantage in terms of price. The cycle number of ordinary lead-acid batteries is more than 300, and that of ordinary lithium batteries is more than 700. In terms of price, ordinary lithium batteries are about twice as expensive as ordinary lead-acid batteries. In this way, lead-acid batteries have no advantages, but also have the disadvantages of heavier weight and slow running.

The lead-carbon battery solves all the disadvantages of lead-acid battery, and its price is similar to that of ordinary lead-acid battery. If lead-carbon battery can reach half the theoretical performance, lead-acid battery will be completely replaced in the future.

Lead carbon battery structure

Lead-carbon battery is a combination of carbon material (C) with double-layer capacitance characteristics and sponge lead (Pb) anode to make a lead-carbon dual-functional composite electrode (referred to as lead-carbon electrode) with both capacitance characteristics and battery characteristics. The lead-carbon composite electrode is then matched with the PbO2 anode to form a lead-carbon battery.

Lead-carbon battery is a mixture of asymmetric supercapacitors and lead-acid batteries in internal parallel. As a new type of super battery, lead-carbon battery is a combination of lead-acid batteries and supercapacitors. It is a dual-function energy storage battery with both capacitance characteristics and battery characteristics. Therefore, it not only gives full play to the advantages of instantaneous power and large-capacity charging of supercapacitors, but also gives full play to the energy advantages of lead-acid batteries, which can be fully charged in an hour. It has good charge and discharge performance.

Principle of lead carbon battery

A new type of battery based on lead carbon technology developed by AxionPower Company in Pennsylvania, the United States, that is, the lead carbon battery, is to mix high specific surface carbon materials (such as activated carbon, activated carbon fiber, carbon aerogel or carbon nanotubes, etc.) into the lead negative electrode, give full play to the high conductivity of high specific surface carbon materials and the dispersibility of lead based active substances, improve the utilization rate of lead active substances, and inhibit the growth of lead sulfate crystals. The principle is similar to that of super battery. It is another kind of super battery. The carbon material is added to the negative plate to give full play to its advantages of instant large-capacity charging of supercapacitors, play a role of buffer during high-rate charging/discharging, effectively protect the negative plate and inhibit the "sulfation" phenomenon.
