Date:24 March 2022

Country: Sweden

Application

• Energy storage: Enhances battery capacity, reliability, and charging speed for next-generation energy solutions.
• High-tech applications: Utilizes graphene's exceptional thermal and electrical conductivity in supercapacitors and other advanced technologies.

Description

Bright Day Graphene, founded in 2017 in Sweden, produces sustainable graphene from lignin, a renewable by-product of the forest industry. Their toxin-free process creates high-quality "green graphene," ideal for energy storage applications like batteries and supercapacitors. This graphene enhances energy capacity by 45%, improves reliability, and reduces charging times. Bright Day aims to revolutionize energy storage and mass-produce premium graphene for various high-tech industries.

Pathway Description:

Bright Day Graphene converts lignin into graphene through a hydrothermal carbonization process. In this method, lignin is subjected to high-temperature, high-pressure conditions in an aqueous environment, breaking down the lignin structure. The process creates graphene-like carbon structures by rearranging the molecular structure of lignin, resulting in a material with properties suitable for energy storage. This method is toxin-free, sustainable, and allows for the scalable production of high-quality graphene from a renewable biomass source.
