The project ran between April and November 2024.
Demand for graphite and hard carbon for use in batteries will increase dramatically to around 4.5 million tonnes in 2050, from today’s 907 thousand tonnes. The Green Deal aims to make the EU’s batteries sustainable and circular, and to increase Europe’s resilience in battery production. In addition, spent coffee grounds are produced in large volumes globally and are an untapped source of biomass for battery production. Selecta coordinated the project aiming to show that spent coffee grounds can be used as a bio-based raw material to produce anodes in lithium-ion and sodium-ion batteries. Coffee grounds were characterized by type, charred, analyzed, and benchmarked against a reference. Granode Materials, an anode manufacturer for LiB batteries, tested the new raw material in next generation batteries and RISE provided expertise and specialized labs for carbonization, slurry formulation, SiB cell assembly and performance testing. The project supported SDG targets 7.2, 9.4 and 12.4.
Participants
Selecta AB, Granode Materials AB and RISE Research Institutes of Sweden AB.
Budget
The project’s total budget was approximately 900 KSEK.
