Consortium Funded for Battery Materials Initiative

Jun 25 2019

Oxfordshire-based Nexeon, a developer and supplier of materials for rechargeable Li-ion batteries – is leading a new project to optimise coating technology for its silicon material. The project named SPICE (Silicon Product Improvement through Coating Enhancement), aims to improve cell performance and also extend the system compatibility of silicon anode materials, allowing use of lower cost electrolyte formulations and lower overall battery cell costs.

Nexeon is working with partners Phoenix Scientific Industries (PSI), AGM Batteries and Oxford University’s Department of Materials and the team has been awarded £2 million in funding through the Government’s ISCF Faraday Battery Challenge by Innovate UK, part of UK Research and Innovation.

Nexeon will lead the project, having already established a laboratory scale coating process for its silicon anode material, and its scale up team has expertise in scaling up high value materials to mass production.

A chemical vapour deposition coating process is being designed by PSI, whose experience in producing a similar system for coating powders for a major aerospace company make it an ideal partner in this project.

AGM Batteries Ltd is the UK’s only cell manufacturer, with significant experience in developing new battery technology and chemistry. Its skills enable the transfer of new products to manufacture. AGM’s role in the SPICE work is to validate the performance of prototype cells incorporating Nexeon’s coated silicon anode powder, and to open its subsequent routes to market.

The project draws on Oxford University Department of Materials expertise to understand what is happening at the molecular level – assessing the uniformity, quality and performance of the special coating, using the UK’s most advanced equipment of its type for the purpose.

“This is an important step in the development of silicon battery materials”, said Dr Scott Brown, CEO of Nexeon. “Using an optimised coating has several important performance advantages, and will further strengthen the case for adoption of silicon anode technology by OEMs and battery makers globally.”
