Bright day graphene

Biobased graphene for green, high-performing batteries and other high-tech applications.

​​​​​​​Bright Day Graphene, a Swedish start-up, has found a new way to produce the super material graphene, from biomass. Our patented process produces a high-performing material, especially suited for energy storage solutions. When used as a conductive additive in the battery cathode, it can more than double the life time, lower the weight, improve fast-charging properties and reduce safety risks.
We call our graphene green, because it’s made from a renewable source instead of a finite resource and we use no toxic chemicals in our production process.
