Graphmatech has announced that a pilot project with Graphenea and Northvolt has upcycled graphene oxide from end-of-life EV batteries. “Producing graphene oxide from end-of-life batteries makes the entire graphene value chain more sustainable and cost-effective,” says Graphenea Advanced Materials CEO Jesus de la Fuente.
“This breakthrough uses the material left after Northvolt has extracted valuable metals and minerals,” says Graphmatech. “Until now, that remaining material has been waste.” Northvolt set up its Northvolt Labs recycling plant to provide graphite-based material with enough purity to support the production of graphene oxide. Graphmatech and Graphenea will use the graphite-based material to scale up graphene oxide production.
Graphmatech’s hydrogen pressure vessels and pipes include modified graphene oxide.
“Modified graphene oxide can be added to metals to create materials which are more conductive, stronger and tougher than alternatives, whilst reducing metal consumption, making it an attractive and useful material within the green transition,” says Graphmatech.
