C-NERGY™
C-NERGY - high-performance graphite and carbon black
C-NERGY is our latest brand of graphite and carbon black products that includes high-purity synthetic graphites with different particle sizes and morphologies, and high purity and high structure carbon blacks developed especially for the lithium-ion battery industry.
As the name suggests, C-NERGY brings together several high-performance grade products, such as those from the L-Series. They are used as conductive additives in the positive and negative electrodes of lithium-ion batteries.
C-NERGY conductive carbon blacks meet the highest purity requirements making them the ideal additive to give electrical conductivity to lithium-ion batteries with low loadings. Their proprietary production process results in the unique combination of high structure and low surface area, which guarantees exceptional distribution in electrode slurries. This is complemented by their low moisture pick up, being highly graphitic to ensure excellent system stability and reduced Open Circuit Voltage (OCV), which reduces rejection rate and improves safety.
