Functional materials firm Toyocolor is set to supply carbon nanotubes to Korea’s lithium-ion battery maker SK Innovations’ plants in the US and Europe.

Toyocolor, the colorants and functional materials division of Japan’s Toyo Ink Group, will supply its Lioaccum series of conductive carbon nanotube (CNT) dispersions. 

Lioaccum dispersions are used as the conductive additive in lithium-ion cathodes to expand battery capacity that enables electric vehicles to increase driving distances and charge faster. 

In this instance, the CNT’s will be used in lithium-ion batteries for Volkswagen Group and the Ford Motor Company.

Toyocolor said in a statement that its researchers in Japan had achieved high conductivity levels by replacing carbon black in the battery cathode with a small amount of Lioaccum CNT dispersions as the conductive additive.

At present, Toyocolor is providing SK Innovation with Lioaccum dispersions produced at its plant in Georgia, US.

Supply to SK Innovation’s European plants is due to move to Toyo Ink Hungary, in Hungary, in the first quarter of next year. 

Toyo Ink SC Holdings, the parent company of the Toyo Ink Group, plans to invest around 10 billion yen ($9990 million) up to 2026, to strengthen its global battery dispersions production network.

Live meetings are back on the agenda as South Korea’s biggest battery expo, “Inter Battery,” opened on Wednesday, when the social distancing measures were lowered to Level 1.

Among the 198 companies showcasing their battery technologies at the expo are: LG Chem, Samsung SDI and SK Innovation.

As Korea’s battery powerhouses boasted their technologies, also hovering over the expo was the word “safety” due to the recent cases of fire from EVs loaded with Korean-made batteries.
