| Abstract Scope |
To meet the simultaneous requirements of high energy and power density for thick lithium-ion electrodes, advanced electrode structuring, or electrode architecture design, must be implemented to avoid liquid-phase, lithium-ion mass-transport losses. Next-generation lithium-ion technologies, such as all-solid-state cells, will also need a thick cathode to be paired with the lithium metal anode. Oak Ridge National Laboratory is developing multiple techniques to mitigate these limitations with partners such as Argonne National Laboratory, Palo Alto Research Center, and Karlsruhe Institute of Technology. This presentation will focus on methodologies such as particle-size and pore-size grading of multilayer thick electrodes, laser ablation structuring and patterning of electrodes, and co-extrusion of interdigitated structures with high and low porosity. Challenges associated with thick, low-Co (high-Ni) cathode processing in water will be discussed. Perspectives on full-scale manufacturing methods for these structures and how they may be integrated with next-generation lithium-ion technologies and active materials will be given. |
