High-Voltage Spinel LNMO Silicon-Graphite Cells and Modules for Automotive and Aeronautic Transport Applications

Project description

A sustainable, high-voltage battery alternative for cars and aircraft

The EU-funded HighSpin project aims to strengthen the position of the European battery industry by delivering the next generation of battery cells for automotive and aviation applications. In particular, it aims to develop a cell with a silicon/graphite anode and lithium nickel manganese oxide cathode. The HighSpin cell will be designed for 2 000 deep cycles and will deliver an energy density of 390 Wh/kg. Project activities will include microstructure optimisation of the active materials, development of high-voltage electrolyte formulations, high-speed laser structuring of the electrodes, and the inclusion of cell-level sensors. Researchers aim to bring the technology to TRL 6.

Objective

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.
