Lead Carbon Battery
Lead Carbon Batteries are a relatively new and significant battery energy storage technology that evolved from the lead acid batteries used in cars for over 100 years. Right off the bat, this makes which makes Lead Carbon Batteries easy to understand and maintain.
What can destroy a lead acid battery?
Lead acid batteries are one where you physically shorten the life if you continue to discharge a battery, even below 50% charge. If you leave the car lights on for several days, it can kill the battery, especially if there is a freeze and a dead lead acid battery is filled with water and can freeze and ruin the battery plates, or even the outside case.
Lead Carbon Battery
Better partial state-of-charge performance, more cycles, and higher efficiency
Replacing the active material of the negative plate by a lead carbon composite potentially reduces sulfation and improves charge acceptance of the negative plate.
The advantages of lead carbon therefore are:
– Less sulfation in case of partial state-of-charge operation.
– Lower charge voltage and therefore higher efficiency and less corrosion of the positive plate.
– And the overall result is improved cycle life.
Lead carbon battery performance
The charging time of lead-carbon battery is one-eighth of that of lead-acid battery, and the cycle life is more than four times that of lead-acid battery. Compared with lithium battery, it also has the advantages of low temperature performance, low cost, mature production and recycling process, etc. The performance has also been greatly improved, and the industrial application of lead carbon batteries in the field of energy storage has begun to mature.
Yang Yusheng, an academician of the Chinese Academy of Sciences, believes that lead carbon batteries have been successfully applied to urban microgrids, wind energy storage power stations, wind circuit lights, etc. due to their significant advantages such as low cost, safety, easy availability of raw materials, reliability, and mature industrial technology. Providing kinetic energy for various electric vehicles is an energy storage battery that conforms to China’s industrial layout and manufacturing level.
Composition of lead carbon battery
The lead carbon battery is a special capacitive lead-acid battery. The traditional lead-acid battery unit is composed of a lead dioxide positive plate and a sponge lead negative plate, while the asymmetric super capacitor is made of lead dioxide positive electrode. The plate and the carbon negative plate are composed. Since the two have a common positive plate, they can be combined in the same battery system, that is, a so-called lead carbon battery is formed. Figure 1 shows the evolution and changes in the structure from traditional lead-acid batteries to lead-carbon batteries.
