Nexeon to build first volume production plant for Panasonic silicon batteries
Nexeon has secured a site for its first commercial volume silicon anode material plant in Gunsan, South Korea.
The plant will use existing available land adjacent to a plant by OCI. Nexeon has also signed a binding deal with OCI for long-term supply of monosilane, a critical raw material required for the production of its second silicon anode materials. The silane is a waste product from the adjacent plant.
Through the contract, OCI will supply monosilane to Nexeon from 2025. Nexeon’s first commercial facility will be established on land adjacent to OCI’s Gunsan plant to deliver tens of thousands of tonnes of silicon anode material annually.
Supply of commercial material begins in early 2025, initially fulfilling the recently announced binding supply agreement with Panasonic.

This infrastructure provides an advantage in cost competitiveness as it uses a by-product gas produced during the manufacturing of polysilicon for semiconductors at the Gunsan plant. It also enables both companies to take advantage of avoiding complex and expensive logistics operations and equipment associated with transporting gas chemicals.
OCI will deliver the raw material through a dedicated and direct pipeline between both facilities, called a ‘fence-line’ infrastructure on the Gunsan site. As Nexeon expands production capacity, OCI has the capability to increase supply lines in parallel to enable production of silicon anode material in the tens of thousands of tonnes per year.
“The collaboration with OCI is a significant milestone that will help rapidly scale our operations. Between securing a strong supply chain of raw material and our supply agreement with Panasonic, we are one step closer to delivering the best performing and cost-efficient silicon anode materials – a vital enabler of more energy dense batteries” said Scott Brown, CEO of Nexeon.
The silicon-based dropped into existing battery manufacturing lines without requiring critical changes to the cell manufacturing process or significant capital investment.

“We expect that high-tech materials company OCI, and Nexeon who have the leading silicon anode material technology, will maximize their strengths to produce products with quality as well as price competitiveness,” said Kim Taek-Joong, vice chairman of OCI.
