One person's waste is another's resource.

Today’s carbon-based supercapacitors are expensive, but recently scientists at Imperial College London have found that they can use lignin to replace the graphene-based carbon used in supercapacitors today. The lignin-derived material can store more electrical energy for a given volume than carbon-based components and it is cheaper.

Finnish company Stora Enso is piloting production of a sustainable graphite replacement for lithium ion battery anodes made from lignin. Range and performance are as much about weight reduction as power and energy storage.

Under the skin: Is the paper industry's waste the car world's gain? | Autocar

The 100 million tonnes of naturally occurring lignin produced as a by-product of paper-making annually could lead to lighter, cheaper, long-range EVs

www.autocar.co.uk

A year later:

Northvolt will use Stora Enso’s lignin-based hard carbon anode material, Lignode, to produce battery cells and ultimately a sustainable battery made from raw materials sourced from Nordic forests. When the battery goes into production, it will be the first to be made entirely from European raw materials on an industrial scale.
