Background
Stellantis is a constellation of 14 iconic automotive brands and two mobility arms. In March 2022, Stellantis presented Dare Forward 2030, a holistic plan that paves the way for Stellantis to transition to a sustainable mobility tech company that delivers value for all stakeholders. The core targets of this strategy include slashing carbon emissions to achieve carbon net zero in 2038 and setting to course for 100% BEV sales in Europe. Developing battery materials with a lower carbon footprint are important to achieve these aims.
In an NMC (Nickel Manganese Cobalt) battery, the anode is generally made of graphite, a crystalline form of carbon where the carbon atoms are arranged in a hexagonal structure. This graphite is usually natural graphite (extracted from mines), or synthetic graphite (produced from coke or coal tar pitch).
Biochar has been identified as a promising alternative source of graphite. Biochar is a high carbon material, produced from the pyrolysis of biomass. Biochar production is a way to valorise unused waste by capturing carbon initially absorbed from the atmosphere through photosynthesis.
The motivation of this challenge is to produce graphite from biochar to reduce carbon footprint, production costs and dependence on virgin raw material supply. The solution could help reduce the carbon footprint and improve the resilience of Stellantis’s global supply chains by allowing localised production and less reliance on natural and synthetic graphite which is only available in certain regions.
The Challenge
The proposed solution must cover a process or approach which produces graphite at suitable quality for battery anodes from an initial biomass source or directly from biochar.
The maturity level of the proposed solution must be ≥ TRL4 including:
- Demonstration of the approach in an operational experimental pilot
- An assessment of graphite quality compared to the high-grade graphite standards for batteries application
- An assessment of overall production costs (CAPEX+OPEX) in the limit of the boundaries defined above
- A CO2 footprint assessment per tonne of produced graphite
- An assessment of energy demand per tonne of produced graphite
The process should be harmless for humans and environment, considering viable control measures.
-
The solution must/should:
- Feasibly produce sufficient graphite for automotive batteries once fully developed. In the context of this challenge, a solution that can produce a few hundred kilograms at a pilot scale would be good.
- Use feedstocks from locally available materials in different regions to allow scaling to different international locations
- Provide an overview of the proposed supply chain
It is expected that the process will need to be developed to pilot plant scale. Successful demonstration could then lead to larger scale and commercially ready operations.
-
The solution must be able to produce graphite of a suitable quality for typical battery applications. Solutions will be assessed based on information provided on the quality of the graphite that can be produced so details should be included in the application on:
- Concentrations of pollutants
- Density
- Particle size distribution
- Porosity
- Carbon content
The solution, once fully developed, must also have lower energy demand and CO2 footprint than current state of the art solutions from natural graphite and synthetic graphite production processes. Information to support this should be provided in the application.
-
The solution must:
- Produce graphite for use as an anode within a Li-ion battery
- Comply with EU regulations for pollutants emissions
Meet the following Stellantis High-Quality Criteria:
- No harm: prove no negative environmental, social or economic impact by preparatory analysis, collaboration with local communities, robust planification & regular monitoring
- No leakage: avoid displacing or creating emissions by preparatory analysis, collaboration with communities and robust planification
- If the solution starts from biomass as input material, this biomass must not cause competition with food
-
- Solutions that do not comply with the Stellantis High-Quality Criteria of No harm and No leakage
- Solutions where the source of biomass is in competition with food
-
The levelised cost of the solution can be higher than current production costs for natural and synthetic graphite, but it must demonstrate quantitively lower CO2 footprint. However, cost is an important consideration so solutions that can achieve lower costs once developed are preferable.
-
Successful applicants will be given an opportunity to pitch to Stellantis. The applications will be reviewed by technical experts in battery materials at Stellantis. Selected solutions may be co-developed towards commercial adoption through co-development, pilot studies or other arrangement depending on mutual agreement between Stellantis and the solution provider.
