SUPER C65 Carbon Black Powder for Lithium Ion Battery Electrodes

The C65 is a high performance conductive carbon black powder. SUPER C65 is an ultra-high purity product that has been used as a conductive additive in lithium ion battery electrodes (cathode and anode) to improve the battery performance.

a. The lowest Fe impurity level (1 ppm)
b. High specific surface area (62 m2/g)
c. Superior battery performance
The primary purpose of use of these SUPER C65 carbon black is to provide electrical conductivity to lithium-ion battery electrodes at low to very low loading.

Application Benefits:
Increased battery safety
Lower rejection ratio
Fully compatible with most electrolyte systems
No additional pre-dispersing is needed
No dispersing aid is needed
Very high loading is possible
Cost savings on NMP and faster drying time
High energy density
Improved power density
Cost reduction thanks to lower dosage needed
Improved flexibility of the electrode
