Global carbon nanotube (CNT) specialist J.O Co., Ltd. announced on the 2nd that it has signed its first contract with a domestic secondary battery-related client company to supply a dry electrode process plant. With this contract as momentum, the company plans to expand its dry electrode process facility business, which is attracting attention as a next-generation secondary battery manufacturing technology.
The equipment supplied by J.O consists of a secondary battery dry dispersion facility, a cathode active material carbon coating, and a cathode composite composition pretreatment facility. The dry electrode process is a method of directly coating a solid-state active material onto a current collector, omitting the drying step that was essential in the wet process.
The dry electrode process consists of a dry dispersion facility for carbon nanotubes (CNTs), which are the conductive material, a facility for coating and fiberizing them onto positive and negative electrode active materials, a roll-to-roll facility for rolling the fiberized material, and a packaging facility. Among these, J.O. has completed the development of a carbon nanotube dry dispersion facility and a dry coating and fiberization facility.
The company said that while it will continue to expand its carbon nanotube business as a secondary battery conductive material, it plans to expand its business area to the positive electrode active material field based on its dry process core technology. It currently supplies multi-walled carbon nanotubes and few-walled carbon nanotubes as secondary battery conductive materials, and is focusing on securing mass production technology and expanding production capacity for single-walled carbon nanotubes for cathodes.
A J.O official said, “We have secured carbon coating for positive electrode active materials and pretreatment facilities for composite compositions, as well as related process technologies, and are conducting business in earnest targeting global secondary battery customers, electric vehicle companies, and active material manufacturers,” adding, “We plan to actively expand new businesses in the secondary battery materials sector by 2028 based on dry process facilities and plant technology.”
