Which lithium battery conductive agent is better?

Lithium battery conductive agents are divided into metal conductive agents and carbon conductive agents according to the material; currently the most important ones are carbon conductive agents, including: Super-P, acetylene carbon black, graphite, VGCF, CNT, etc. In terms of resistivity, CNT has the smallest resistivity, followed by VGCF, and Super-P has the largest resistivity; however, the problems faced by VGCF and CNT are dispersion and price issues; some domestic lithium battery manufacturers are studying the dispersion Conductive liquid, but the effect is not very good, and the cost performance is not cost-effective, so the most used conductive agent is Super-P and conductive graphite. In addition, acetylene carbon black is also effective. The most important thing is nano-superconducting acetylene carbon black. Adding a small amount can greatly improve the conductivity. At present, most lithium battery processing manufacturers use composite conductive agents, which is to mix several conductive agents: the commonly used combination is SP+KS series; or SP+VGCF, etc.; even some manufacturers use 3-component conductive agents.
