6 FAQs about [Application scope of conductive agent for energy storage batteries]

Should conductive agents be selected for dry-processed electrodes?

This study reports the importance of selecting appropriate conductive agents for dry-processed electrodes and optimizing the electrode composition based on the design principles by electrode parameters.

Which conductive additives are used in electrode slurry?

In this research, we compared three electrically conductive additives: PEDOT:PSS (poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate), further PEDOT) conducted binder polymer, conventional additive Super P carbon black (CB), and carbon nanotubes (CNT). Electrode slurry components’ names and proportions are presented in Table 1.

Are carbon nanotubes conductive additives for high-power Li-ion batteries?

A thorough comparison of three conductive additives demonstrates that carbon nanotubes are the most compatible and promising conductive additives for modern conventional manufacturing of high-power Li-ion batteries. Decades of Li-ion batteries (LIBs) development have resulted in their widespread adoption in our everyday life.

What are conductive additives?

Currently, perspective conductive additives such as carbon nanotubes [16, 17, 28], graphene [28, 29], and other electrically conductive binder [30, 31] are widely studied. Each of the above components allows to increase the weight content of the active material, without compromising the conductive properties.

Does porous spherical conductive agent improve lithium-ion transport characteristics?

By applying various conductive agents in the dry process, we discovered that the porous spherical conductive agent improves both the electrical performance and lithium-ion transport characteristics, which are difficult to incorporate in conventional wet processes.

Which Binder/carbon black ratio is best for a lithium ion battery?

In a theoretical study, it was shown that a binder/carbon black ratio of less than 4 achieves the best LIB performance, and the most optimal ratio is 90% of the active material; a binder and conductive additives (carbon black) are from 2 to 8% . The ratio of the latter is selected depending on battery types and conditions of use.
