LG Chem said on Wednesday that its second carbon nanotube (CNT) factory at Yeosu has finished construction and began production.

With the factory going live, the company’s annual CNT production capacity has now increased from 500 metric tonnes to 1,700 metric tonnes.

CNT has the same levels of heat conductivity to copper and diamonds, but has hundred times the strength of steel.

It is used in battery, semiconductor, automobile components and other devices.

LG Chem said its second factory at Yeosu was the world’s largest single production line for CNT.

The firm applied its self-developed fluidized bed reactor to increase the line’s production capacity. It also automated the whole production process than reduced power consumption by 30%, the company said.

LG Chem will be supplying CNT to LG Energy Solution and other customers.

Use of CNT as conductive material can increase conductivity by 10% compared to carbon blacks. This will allow batteries to pack in more cathode than conductive agents, which will increase its energy density and life span.
