Nexeon in the UK is to start supplying silicon anode material to Panasonic in a partnership for the next generation of higher energy battery cells in 2025.

The long term supply agreement will see Panasonic Energy develop silicon battery cells for electric vehicles from 2025. Panasonic is a key supplier to Tesla which is also working on silicon battery cells.

Nexeon’s material has the potential to boost the energy density of lithium-ion cells by up to 50%. The ‘drop-in’ material allows Panasonic to use a much higher percentage of silicon in lithium-ion cell anodes when compared with first generation materials such as silicon oxide, without requiring critical changes to the cell manufacturing process or significant capital investment.

“The partnership with Panasonic is a testament to the progress we have made with our battery material technology,” said Scott Brown, CEO of Nexeon. “Our silicon anode material will bring dramatically improved vehicle range and charging speeds for EVs, helping to address drivers’ concerns and accelerate the transition to cleaner forms of mobility.”

“This collaboration will help us drive growth of the lithium-ion battery industry and accelerate the world towards a net-zero emissions future,” said Shoichiro Watanabe, Executive Vice President of Panasonic Energy. “By integrating Nexeon’s silicon battery material with our advanced cell manufacturing capabilities, we believe that we can address the concerns such as range anxiety and charging time and contribute to accelerating the adoption of EVs.”;
