Nexeon, a UK-based developer of silicon-based anode materials for lithium-ion batteries, has received an investment from Honda through the automaker’s Honda Xcelerator Ventures programme.
The companies did not disclose the financial terms of the transaction. Nexeon said the funding will support ongoing development and commercialisation activities related to its silicon anode technology.
Honda Joins Nexeon’s Investor Group
The investment was made through Honda Xcelerator Ventures, Honda’s global open innovation initiative focused on emerging technologies and startup partnerships.
Nexeon was established as a spin-out from Imperial College London more than 20 years ago and has previously raised funding from a range of financial and strategic investors. In 2022, the company announced a funding round exceeding US$200 million.
Focus on Silicon-Based Battery Materials
Nexeon develops silicon-based materials for lithium-ion battery anodes. The technology is intended to replace or supplement conventional graphite anodes used in battery cells.
According to the company, silicon-based anode materials can increase battery energy density and support improvements in charging performance.
Nexeon said it has continued development of silicon-carbon materials aimed at next-generation battery applications.
Production Facility in South Korea
The company is currently advancing commercial production through its manufacturing facility in Gunsan, South Korea.
Construction of the plant began in 2023, and Nexeon announced in late 2025 that the site had reached production readiness.
The facility is located adjacent to OCI, which supplies monosilane gas used in the production process. Previous company statements indicated that the plant is designed to produce tens of thousands of tonnes of silicon anode material annually.
Industry Partnerships
Panasonic has previously been identified as a customer for Nexeon’s silicon anode materials. The materials are expected to be used in battery cells produced at Panasonic’s manufacturing facility in De Soto, Kansas.
Commenting on the investment, Nexeon Chief Executive Officer Dr Scott Brown said the company plans to continue working with Honda and other industry partners as it expands production capacity.
“We are pleased to welcome Honda as a shareholder as we enter an exciting phase and commercialise our technology, and we look forward to collaborating closely with them and our other partners as we scale production,” said Dr Scott Brown, Chief Executive Officer of Nexeon.
“This funding round is not only a validation of our technology and commercial traction, but also a clear endorsement of the strategic role that Nexeon can play in the global transition to electrification.”
The investment reflects ongoing collaboration between automakers and battery technology companies as the industry continues to explore materials that may support future improvements in battery performance and manufacturing.
