Acetylene carbon black additive for lead-acid batteries
Lead-acid batteries are one of the most common types of batteries, whose positive and negative electrodes are composed of lead and lead dioxide, respectively, and whose electrolyte is a sulfuric acid solution with a concentration of 30% to 40%.
Lead-acid batteries are one of the most common types of batteries, whose positive and negative electrodes are composed of lead and lead dioxide, respectively, and whose electrolyte is a sulfuric acid solution with a concentration of 30% to 40%. In the process of using lead-acid batteries, some problems will occur, such as prone to polar plate sulfation, electrolyte consumption, capacity decline and shortened life. In order to solve these problems, people have researched additives, among which acetylene carbon black additive is one of the more common ones.
Acetylene carbon black is a kind of carbon black produced by the combustion of acetylene, which is characterized by high surface area, high adsorption, high electrical conductivity, high chemical stability, high abrasion resistance and high temperature stability. These characteristics make acetylene carbon black an excellent additive to improve the performance of lead-acid batteries.
Acetylene carbon black can increase the capacity of lead-acid batteries. The capacity of lead-acid battery is mainly affected by the active materials of positive and negative electrodes, while acetylene carbon black can increase the surface area of active materials and improve the reaction activity of electrodes, thus increasing the capacity of the battery.
Acetylene carbon black can reduce the polar plate sulfation. Plate sulfation is a common problem in lead-acid batteries, which will reduce the capacity and life of the battery. Acetylene carbon black can adsorb sulfate ions in the electrolyte, preventing sulfate ions from reacting with lead plates, thus reducing the occurrence of plate sulfation.
Acetylene carbon black can also extend the life of lead-acid batteries. In the process of use, the electrolyte of lead-acid battery will be gradually consumed over time, acetylene carbon black can adsorb the sulfate ions in the electrolyte, slowing down the consumption of electrolyte, thus extending the life of lead-acid battery.
Acetylene carbon black additives can improve the performance of lead-acid batteries, increase capacity, reduce plate sulfation and extend life. When using acetylene carbon black additives, it is also necessary to pay attention to the addition amount and control conditions to ensure the stability and safety of lead-acid batteries.
