Nexeon, the Abingdon-based company which develops and produces materials for better batteries, has secured funding from Innovate UK for a new research initiative. The £1.5 million Silicon Anode Battery for Rapid Electrification (SABRE) project will develop battery cells with higher energy density, in response to the demand for increased EV driving range.
The SABRE project has been awarded funding from the Faraday Battery Challenge at UK Research and Innovation, and Nexeon will work with its partners, Britishvolt and University College London (UCL), to deliver test cells with a combination of advanced Li-ion cell design and novel silicon anode material.
The project starts immediately, and will extend over twelve months. The partners will exploit the potential for Nexeon silicon anode materials, already shown to improve the performance of Li-ion batteries. Silicon has a greater affinity for lithium than graphite, and this enables the production of cells with increased energy density. Nexeon’s highly innovative silicon material design is achieving a combination of high lithium capacity with low volume change for long cycle life.
In the SABRE project, Britishvolt will apply innovative computer-aided cell design and simulation to accelerate the integration of silicon into the anode design. These tasks will be supported by UCL’s Electrochemical Innovation Lab.
The project will also utilise the new cell assembly capabilities at the Coventry-based UK Battery Innovation Centre (UKBIC) which opened recently, for the fabrication of 21700 cells to test and validate the new cell design.
Dr Scott Brown, CEO of Nexeon, said: “We are very excited to lead this important work, and to collaborate with our partners in designing and producing higher performance battery cells.
“This project, and others like it, are important in building a UK-based lithium ion battery capability, and reducing risk in an increasingly competitive supply chain.”
