The C-NERGY SUPER C65 is a high performance conductive carbon black powder made by IMERYS. SUPER C65 was introduced by IMERYS as an improved version of the SUPER P carbon black. 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.
Advantages:
a. The lowest Fe impurity level (1 ppm)
b. High specific surface area (62 m2/g)
c. Superior battery performance
The Imerys C-NERGY SUPER C65 carbon black meets the highest purity requirements for low metallic impurities and grit. 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

Abstract
Thicker electrode layers for lithium ion cells have a favorable electrode to current collector ratio per stack volume and provide reduced cell manufacturing costs due to fewer cutting and stapling steps. The aim of this work is to investigate the delivery of energy in such cells compared to cells with thinner electrodes. In this regard, lithium ion cells with single sided 70 um and 320 um NMC based cathodes and graphite based anodes with low binder and carbon black (SUPER C65) contents were prepared and tested in half cell and full cell configurations. Thick and thin electrodes showed capacity losses of only 6% upon cycling at C-rates of C/10 and C/5 while cycling at C/2 resulted in significant losses of 37% for the thick electrodes and only 8% for the thin electrodes. Pouch cells with thick electrodes showed 19% higher volumetric energy density at C/5 in comparison to thinner electrodes. This can be an innovative approach to reduce cell costs and to achieve more competitive prices per energy for applications where only medium to small C-rates are required.
