Descrizione del progetto
Un’alternativa sostenibile alle batterie ad alta tensione per automobili e aeromobili
Il progetto HighSpin, finanziato dall’UE, si propone di rafforzare la posizione dell’industria europea delle batterie fornendo la prossima generazione di batterie per applicazioni automobilistiche e aeronautiche. In particolare, mira a sviluppare una cella con anodo in silicio/grafite e catodo in ossido di nichel manganese e litio. La cella HighSpin sarà progettata per 2 000 cicli profondi e fornirà una densità energetica di 390 Wh/kg. Le attività del progetto comprendono l’ottimizzazione della microstruttura dei materiali attivi, lo sviluppo di formulazioni di elettroliti ad alta tensione, la strutturazione laser ad alta velocità degli elettrodi e l’inclusione di sensori a livello di cella. I ricercatori mirano a portare la tecnologia al livello di maturità tecnologica 6.
Obiettivo
HighSpin aims to develop high-performing, safe and sustainable generation 3b high-voltage spinel LNMO||Si/C material, cells and modules with a short industrialisation pathway and demonstrate their application for automotive and aeronautic transport applications. The project addresses in full the scope of the HORIZON-CL5-2021-D2-01-02 topic, setting its activities in the “high-voltage” line. The project objectives are:
• Further develop the LNMO||Si/C cell chemistry compared to the reference 3beLiEVe baseline, extracting its maximum performance.
• Develop and manufacture LNMO||Si/C cells fit for automotive and aeronautic applications.
• Design and demonstrate battery modules for automotive and aeronautic applications.
• Thoroughly assess the LMNO||Si/C HighSpin technology vs. performance, recyclability, cost and TRL.
The HighSpin cell delivers 390 Wh/kg and 925 Wh/l target energy density, 790 W/kg and 1,850 W/l target power density (at 2C), 2,000 deep cycles, and 90 €/kWh target cost (pack-level). The project activities encompass stabilisation of the active materials via microstructure optimisation, the development of high-voltage electrolyte formulations containing LiPF6 and LIFSI, high-speed laser-structuring of the electrodes, and the inclusion of operando sensors in the form of a chip-based Cell Management Unit (CMU). HighSpin will demonstrate TRL 6 at the battery module level, with a module-to-cell gravimetric energy density ratio of 85-to-90% (depending on the application). Recyclability is demonstrated, targeting 90% recycling efficiency at 99.9% purity. HighSpin aims at approaching the market as a second-step generation 3b LNMO||Si/C in the year 2028 (automotive) and 2030 (aeronautics), delivering above 40 GWh/year and 4 billion/year sales volume in the reference year 2030.
