Upscaling of 3D Electrode Architectures for High-Performance EV Batteries

3D architectures in high-mass-loaded electrodes have significant impact for electrochemical performance of lithium-ion batteries, such as cycle lifetime, lithium-plating, cell degradation, and high-rate capability. Fast charging and high power operation for high energy batteries with thick-film electrodes becomes possible. Ultrafast laser structuring of cathodes and anodes in roll-to-roll processes is currently being upscaled to push this technology towards TRL6 and beyond.
