Si-DRIVE will develop the next generation of rechargeable Li-ion batteries, allowing for cost competitive mass market electric vehicles (EV) by transformative materials and cell chemistry innovations, delivering enhanced safety with superior energy density, cycle life and fast charging capability using sustainable and recyclable components. The Si-DRIVE technology will exceed the stringent demands of EV batteries where safety is paramount, by dramatically improving each component within the accepted Li-ion platform and achieving this in a market competitive process with whole of life considerations. The Si-DRIVE consortium boasts the required academic and industrial partner expertise to deliver this technology and spans material design and synthesis, electrochemical testing, prototype formation and production method validation, life cycle assessment and recycling process development


Si-DRIVE intends to make Li-Si a market ready and safe rechargeable battery
technology for electric vehicles, by dramatically improving energy density (ED), power density, charging rates, lifetime and manufacturability. The following aims will be reached:
- Innovative technology to deliver safe, energy dense and fast charging Li-ion batteries for EVs in a cost effective and resilient manufacturing process embedded in Europe.
- Exploitation of new materials at Anode, Electrolyte and Cathode optimised by full-cell experiment and theoretical modelling to understand and control interfacial processes.
- Materials optimisation to achieve long term operation (1000 cycles 1st life) and 5000 cycles (2nd Life) with 50% recyclability.
- Develop a Li-ion technology consistent with EV roadmaps (ERTRAC, SET plan, EUROBAT) that have identified Li-ion with or without solid electrolyte as the technology solution that will be acceptable to EV manufacturers.
