CATL adopts use of Toyocolor conductive carbon nanotube battery materials

Chinese battery-maker CATL has chosen to use Japan-based Toyocolor‘s Lioaccum conductive carbon nanotube (CNT) dispersion for its high-capacity Li-ion batteries. The batteries will be installed in mass-produced vehicles beginning in 2024. 

According to Toyocolor, its Lioaccum dispersion CATL contributes to expanded battery capacity and energy density through adoption of highly conductive CNTs. Battery cathodes consist mainly of active materials, conductive materials and a binder, and by substituting CNTs for conventional carbon black as the conductive material, Toyocolor says it has achieved superior conductive performance with a nominal amount of material.

To meet CATL’s supply needs, Toyocolor will be expanding the capacity of its dispersion production base, Zhuhai Toyocolor, in Guangdong, China.
