For Generation 4a (solid state with conventional materials) projects are expected to cover all bullets:

• Developing low direct current resistance active materials
• Reducing thickness of the anode
• Developing thin solid electrolyte with high ionic conductivity
• Developing concepts/strategies for manufacturing new solid electrolyte interlayers
• Improving interface design to ensure efficient charge-transfer and electrochemical stability and improved cell mechanical stability
• Proposed approach is expected to have no negative impact on energy densities, safety, and cyclability
• Development of coating strategies for current collectors

For Generation 4b (solid state with Li metal-based anode materials) projects are expected to cover one or several bullets:

• New materials and/or chemistries to increase the energy densities beyond the state of the art of batteries used in electro mobility applications.
• At the anode side, lithium metal appears as the most appealing choice in terms of gravimetric energy density.
• Improved reversibility, homogeneity and density of electrodeposition process by doping or coating strategies.
• Solutions for manufacturing and handling Li metal sheet in dry atmosphere.
• Novel solutions for low cost manufacturing strategies such as solvent-free electrode manufacturing and solid electrolyte deposition.
• Another technology (anode-less), could also be developed by designing current collectors for reversible electrodeposition of lithium. Current collector coating strategies which regulate lithium deposition and improve cycling performance can also be developed.
• Solid-state electrolytes and lithium metal anodes open the way to new cathode chemistries reaching high energy density such as lithium-free cathode in combination with lithium metal or Li-excess cathode exhibiting high irreversible capacity in the anode-less configuration.
• Improving interface design to ensure efficient charge-transfer and electromechanical stability and improved cell mechanical stability.
• Bipolar cell design concepts and processing.
