Lithium-ion Batteries

Lithium-ion Batteries

Imerys Graphite & Carbon is the global leader in conductive additives for lithium-ion batteries.

Our C-NERGYTM line of extremely high purity graphites and conductive carbon black powders are used as conductive additives in the positive and negative electrodes of lithium-ion batteries.

The benefits of our products include:

  • Increased energy and power density
  • cost reduction and operational efficiency
  • improved battery safety

Our C-NERGYTM Actilion GHDR grades for the active mass of the negative electrode are made with our patented  chemical vapor deposition coating – an environmentally friendly alternative to pitch coating.

In addition, we have just introduced a new line of additives for the active mass. Adding a small percent of our QX Quick Charge line to your active mass will significantly improve your battery’s charge and cycling rate, especially at low temperatures.

Finally, our carbon-based dispersions are an ideal coating for the aluminum current collector.
