Add acetylene black to battery plates (lead acid battery, lithium battery, lithium ion battery, polymer battery, air battery, etc.) to absorb more electrolyte and improve the ion conductivity of the electrodes.
The particle diameter of acetylene carbon black is at the middle level. It has very high structure, low ash and volatile content, so the resistivity is very low. The acetylene carbon black for lead battery can enhance the battery storage time, and extend its service life. The conductive carbon black (35-40nm) through high-temperature cracking and decomposition of acetylene carbon black normally refers to the high-performance carbon black which is collected after cooling and thermal cracking and decomposition of purified acetylene gas at a high temperature and isolated from air, while acetylene is made with calcium carbide. The high-performance carbon black is commonly known as acetylene carbon black, ACET for short.
The oil absorption value is often used to indicate the structure. The higher oil absorption value, the higher structural performance of carbon black. It can easily form the space network channel and can’t be damaged easily. The high structural carbon black boasts fine particles, tightly piled network chains. It’s larger than the surface area and there are more unit granular mass, which benefits formation of the chain conductive structure in the polymer. Among a large variety of carbon black, acetylene carbon black is a perfect choice.
In addition, among all kinds of conductive carbon black, as acetylene black has quite stable chemical properties, it will not react with acid, alkali and water easily. Therefore, it has become a necessary and significant material in producing battery plates of lead storage battery, lead acid battery, lithium battery, lithium ion battery, polymer battery, air battery and the like.
