Pioneer projects are initiatives aimed at improving the level of technical readiness (TRL) of graphene technology, and each Spearhead project is led by an industry-leading company with specific business objectives. Their respective goal is to produce a high-TRL prototype or market-ready product by the end of the current phase of the graphene flagship in 2023.
Graphene Flagship's commitment to the Spearhead project is unshakable, and our total one-third of our capital is invested in these companies, a bold move to maximize the impact of Graphene Flagship in the innovation ecosystem and the European economy."
By the end of Graphene Flagship Core 3 in 2023, Spearhead Project GrEEnBat plans to enter a four-year automotive development cycle with its battery module.
Graphene flagship pioneer project GrEEnBat's automotive batteries use graphene as a high-quality anode. The GrEEnBat Spearhead project aims to expand the manufacture of lithium-ion battery anode silicon/graphene composite electrodes and develop full-featured battery modules for automotive applications.
Key innovations in the device have been developed and patented in the previous phase of the development of the graphene flagship project. By 2025, all target specifications for materials, batteries, and modules will be able to compete with the most advanced modules predicted.
GrEEnBat's R&D efforts are focused on increasing the production of high-quality anode materials to a scale of one ton per year. In 2020, their team surpassed the surface capacity and recyclability of the same electrode produced in the previous stage of the graphene flagship by 40% and 10%, respectively.
The team is also working on optimizing their electrode formulations, electrolyte formulations, and battery designs. Full unit testing helps narrow down the target specifications for future prototype unit buildings and module demonstrations.
Lithium-ion batteries for automotive applications and electric vehicles can greatly contribute to reducing global greenhouse gas emissions if electricity comes from sustainable and renewable sources.
