Silicon based materials and new processing technologies for improved lithium-ion batteries

Project description

A new energy storage solution that is long-lasting and cost-effective

In Europe’s race to achieve ambitious climate energy objectives, one challenge stands out: energy storage. As the continent seeks sustainable solutions, the EU funded SINTBAT project aims to develop a cost-effective and maintenance-free lithium-ion energy storage system with an exceptional lifespan of 20 to 25 years. By harnessing advanced analysis methods and innovative materials, SINTBAT targets precise lifetime predictions, heightened performance, and substantial cost reductions. With the potential to bring cell costs down to EUR 130 per kWh, battery based storage systems could become economically viable, supporting Europe’s pursuit of a greener future. Taking a holistic approach, the project’s consortium will establish an Industrial Advisory Board encompassing various European battery material suppliers, cell manufacturers, and end users.


According to the European Energy Storage Technology Development Roadmap towards 2030 (EASE/EERA) energy storage will be of the greatest importance for the European climate energy objectives. The Sintbat project aims at the development of a cheap energy efficient and effectively maintenance free lithium-ion based energy storage system offering in-service time of 20 to 25 years. Insights gained from advanced in-situ and in-operando analysis methods will be used for multi scale modelling targeting on the simulation of aging mechanisms for a reliable lifetime prediction and enhancement. In addition, the latest generation of anode materials based on silicon as well as a prelithiation process for lifetime enhancement will be implemented in the cell manufacturing process. The implementation of high energy materials combined with a low cost and environmental benign aqueous cathode manufacturing process will lead to remarkable cell costs reduction down to 130 € per kWh. This will enable battery based storage system for an economic reasonable price of less than 400 € per kWh (CAPEX) and will lower the OPEX down to less than 0.09 € per stored kWh for the targeted in-service time of 20 to 25 years (10,000 cycles). The technical developments will be supported by the set-up of a relevant roadmap as well as a catalogue for good practice. To guarantee the highest possible impact for the European economy the Sinbat consortium installed an Industrial Advisory Board including various European battery material suppliers, cell manufacturer and end-users whereby the whole value added chain in this way is completed within the Sintbat project. This strong interaction of the Sintbat consortium with relevant stakeholders in the European energy economy will assure that battery based energy storage systems are becoming an economic self-sustaining technology.
