What to know before you buy
This collection groups anode battery materials and the carbons used to build electrodes around them. It suits labs making test anodes, studying new carbon hosts or adding conductivity to electrode slurries.
For metal anodes and counter electrodes, there are battery grade sodium metal chips for sodium-ion half cells. Carbon structures include multi walled carbon nanotubes and carbon nanofibers, carbon nanotube sponges, ordered mesoporous carbon CMK-3, mesoporous nano carbon for lithium-sulfur work and fullerenes C60 and C70.
Conductive additives are mixed into anodes and cathodes alike. Options include Super P, Super C45, Super C65, Ketjenblack EC600JD and acetylene black. Choose by surface area and how much additive your electrode recipe allows. We also customize anode materials for battery research, so ask if you need a composition or form not listed.
Frequently Asked Questions
Which conductive carbon should I add to my anode?
Super P and Super C65 are common starting points for graphite and silicon anodes. Super C45 has a lower surface area, which can reduce binder demand. Ketjenblack EC600JD has a very high surface area, so small loadings build a network. Compare at the same weight percent.
When should I use carbon nanotubes instead of carbon black?
Carbon nanotubes and nanofibers form long conductive paths, so they can connect particles at lower loading than carbon black. They help with silicon and other anodes that swell during cycling. Many recipes combine a small amount of nanotubes with a carbon black for both short and long range contact.
What carbon host suits lithium-sulfur electrodes?
Porous carbons hold sulfur in their pores and limit polysulfide loss. The mesoporous nano carbon for lithium-sulfur batteries and ordered mesoporous carbon CMK-3 are both used for this. CMK-3 has a regular pore structure that helps when studying pore size effects.
How should I handle sodium metal chips?
Sodium reacts with moisture and air, so open and handle the chips only in an argon glove box. Keep the can sealed when not in use, use dry tools, and cut away any oxidized surface before assembly. Dispose of scraps following your lab procedure for reactive metals.
Can I order a custom anode material or larger amounts?
Yes. We customize anode materials for battery technology. Send the composition, particle size or form and quantity through the quote request form. For larger amounts of a listed material, use the bulk order request form.
