Commonly used conductive agents for lithium-ion batteries can be divided into traditional conductive agents (such as carbon black, conductive graphite, carbon fiber, etc.) and new conductive agents (such as carbon nanotubes, graphene and their mixed conductive pastes, etc.). The types of conductive agents on the market are SPUERLi, S-O, KS-6, KS-15, SFG-6, SFG-15, 350G, acetylene black (AB), Ketjen black (KB), vapor grown carbon fiber (VGCF) , carbon nanotubes (CNTs), etc. 1. Carbon black Carbon black is chain-like or grape-like under scanning electron microscope, and a single carbon black particle has a very large specific surface area (700m2/g). The high specific surface area and tight packing of carbon black particles facilitates the close contact between the particles, forming a conductive network in the electrode. The process problem caused by the larger specific surface is that it is difficult to disperse and has strong oil absorption. This requires improving the ...
