ExpectedOutcome:

Projects are expected to contribute to the following outcomes:

  • Advanced Li-ion batteries delivering on cost, performance, safety, sustainability and recyclability, with clear prospects for cost-competitive large-scale manufacturing and uptake by the electro mobility as well as other application sectors.
  • Increase in energy density and hence increasing driving distance at reduced cost on module and pack level, inducing a broader customer’s acceptance.
  • Broader user acceptance leading to a significantly broader market penetration, helping to reduce GHG emissions of the transport and industry sectors to support EU’s efforts to become climate-neutral by 2050: demonstrated for recyclability.

Translating these outcomes into indicative KPIs to guide the R&I efforts, it is recommended to target the following for impact by 2025 and beyond:

  • Gravimetric, volume energy density at cell level of 350-400 Wh/kg, 750-1000 Wh/l respectively.
  • Power density at cell level of 700 W/kg, 1500+ W/L.
  • For high voltage application, operation at 4.7+ Volt.
  • 3000+ and 2000+ deep cycles for high capacity and high voltage applications respectively.
  • Cost at pack level < 100 euro/kWh.
Scope:

The overarching R&I challenges lie in the development of advanced materials enabling higher energy / power density thanks to higher capacity (voltage range 4.3-4.5V) and/or operating at higher voltage (4.7+V). Focus is on adapting the cathode materials (high-nickel NMCs for capacity, spinels / Li-rich Mn NMCs for voltage), the anode materials (graphite-containing Si(Ox)), the electrolytes (stabilised formulations) and their interplay.

  • For the higher capacity approach, focusing on maximising energy and power density should address topics such as
    • High-capacity cathode materials operating in 4.3-4.5 Volt range while delivering on cycle life, protective coatings for safety improvements;
    • High-performance anodes with advanced graphite and silicon materials (increase Si content in Si/C anodes to achieve capacities ideally at 1000 mAh/g), - Other option is to, develop complete Si or other alloying anode solutions in nanostructured form;
    • Suitable inactive materials (binders, conductive carbons, current collectors, separators);
    • Electrolytes stable in 4.3-4.5 Volt (new additives and/or solvent systems), advanced processing routes for the novel materials and advanced electrode and cell/module designs.
  • For the higher voltage approach, focusing on maximising energy and power density should address topics such as
    • High-voltage stable electrolyte systems (new electrolytes and/or new formulations);
    • High-voltage stable cathode active materials (e.g. HV spinels, Li-rich Mn NMCs, phosphates, disordered materials etc. with lowered content in critical and high price elements, protective coatings);
    • Tailoring and operando monitoring of the electrochemical interplay between the cathode active material and the electrolyte formation of stable SEI interfaces;
    • Advanced high performance anodes matching these high-voltage cathodes and electrolytes;
    • Structuring of the cathode and anode electrodes for among others their competition and electric conductivities.
