Nexeon to build anode materials plant in South Korea

British anode material developer Nexeon plans to build its first commercial production site in South Korea. According to official company statements, the plant being built in the industrial city of Gunsan will enable the company to meet its binding supply agreement with Panasonic in early 2025.

Several tens of thousands of tons per year

The land in question is to be adjacent to the production facility of OCI, which will supply monosilane, a key raw material for the production of Nexeon’s silicon anode materials, in the long term. OCI would supply the raw material through a dedicated and direct pipeline between the two facilities at the Gunsan site. OCI plans to expand the supply pipelines in parallel, which will allow for the production of silicon anode material at a rate of tens of thousands of tons per year, he said.

50 percent higher energy density

Nexeon’s silicon-based anode material is said to have the potential to increase the energy density of lithium-ion cells by up to 50 percent. The Generation 2 “drop-in” materials are said to allow cell manufacturers to use a much higher silicon content in lithium-ion cell anodes compared to first-generation materials, such as silicon oxide, without requiring critical changes to the cell manufacturing process or significant capital investment.
