Acetylene carbon black, as a crucial industrial material, plays an important role in many fields, especially in electrochemical applications such as lithium thionyl chloride batteries. Among them, there is a close and subtle connection between its oil absorption value and conductive performance, which deeply affects the performance of related products.

The oil absorption value, as an important indicator for measuring the adsorption capacity of acetylene carbon black, is usually expressed by the amount of a specific oil (such as linseed oil) adsorbed by a unit mass of carbon black. The level of the oil absorption value essentially reflects the microscopic structural characteristics of acetylene carbon black. Acetylene carbon black with a high oil absorption value often has a more developed and complex microscopic structure, presenting abundant branches and pores, similar to a highly intricate three-dimensional network architecture. This unique structure provides advantageous conditions for electron transmission. In the electrode material system, when acetylene carbon black is mixed with other active substances, the complex structure of carbon black with a high oil absorption value can act like a bridge, enabling more extensive and continuous connections among active substances. Electrons encounter relatively fewer obstacles when shuttling through it, thus being able to migrate efficiently, greatly promoting the formation of conductive pathways and significantly improving the overall conductive performance of the material.

Conversely, acetylene carbon black with a low oil absorption value has a relatively simple and compact structure. It has fewer branches and pores, and its microscopic morphology is relatively regular. Such a structure has obvious disadvantages in constructing conductive pathways. The transmission paths of electrons in it are not rich and continuous, and they are easily restricted and hindered by the structure itself, resulting in frequent scattering and other phenomena during the conduction process, and ultimately greatly reducing the overall conductive performance.

In practical application scenarios, for example, in the preparation of electrodes for lithium thionyl chloride batteries, it is crucial to accurately control the relationship between the oil absorption value and conductive performance of acetylene carbon black. If the oil absorption value of acetylene carbon black can be reasonably selected and adjusted to optimize its microscopic structure, an efficient conductive network can be constructed, reducing the internal resistance loss of the battery and improving the charging and discharging efficiency and overall performance of the battery. Meanwhile, in other fields where acetylene carbon black is used as a conductive additive, such as the conductive modification of rubber and plastics, a deep understanding of this relationship also helps to selectively choose acetylene carbon black products with appropriate oil absorption values according to specific requirements, optimize the conductive performance design of materials, meet the strict requirements for the electrical properties of materials in different industrial application scenarios, and promote the technological development and product innovation of related industries.
