CNT dispersions for LiBs is adopted by Primearth EV Energy and installed in Toyota's hybrid vehicles

~CNT dispersions adopted for the first time as a conductive additive for lithium-ion batteries for mass-produced vehicles made in Japan~

[The following text was translated using artificial intelligence.]

LIOACCUM ™, conductive carbon nanotubes (CNT) dispersions manufactured by artience group 's TOYOCOLOR CO., LTD. (President and Representative Director Hideki Okaichi, Chuo-ku, Tokyo)  have been adopted by Primearth EV Energy Co., Ltd. (PEVE) as a conductive additive for lithium-ion batteries. This is the first time that CNT dispersions has been adopted as a conductive additive for lithium-ion battery cathode materials for mass-produced vehicles made in Japan. This product has started shipping for hybrid vehicles manufactured by Toyota Motor Corporation.

The conductive CNT for lithium-ion battery cathode materials dispersions LIOACCUM ™, which has been selected for use in Toyota's hybrid vehicles through PEVE, is a key material that enables higher capacity and output of lithium-ion batteries by using a high-conductivity type CNT with a smaller amount of conductive additive than conventional carbon black.

In conjunction with this adoption, TOYO COLOR will expand the facilities of the Fuji Plant, which is TOYOCOLOR 's dispersions production base, to strengthen its production capacity. In addition, in anticipation of an increase in demand in the North American area due to the local production of Toyota's on-board batteries in North America, we will begin preparations for supply from LioChem, Inc., artience group 's North American manufacturing base.

Features of the CNT dispersions LIOACCUM ™ for lithium-ion battery cathode materials

TOYOCOLOR has strengths in carbon dispersion, and has been supplying carbon dispersions for lithium-ion battery cathode materials since 2015, and has accumulated trust and achievements as a lithium-ion battery material manufacturer.
The cathode material of a lithium-ion battery is mainly composed of an active material, a conductive additive, and a binder. By using CNT instead of carbon black as the conductive additive, conductive performance can be achieved with a small amount of conductive additive. TOYOCOLOR has dramatically increased the dispersibility and conductivity of CNT using proprietary additives and dispersions manufacturing methods, and has succeeded in significantly reducing the resistance value of lithium-ion battery cathodes with less usage.
This will reduce the cost of conductive additives for lithium-ion batteries and increase the capacity of batteries by increasing the amount of active material in the cathode, thereby extending the cruising range of HVs, PHVs, and EVs and improving the fast charging performance.
