Sustainable and cost-effective electrode manufacturing for advanced lithium batteries: the roll-to-roll dry coating process

The transition to electric vehicles motivated by global carbon neutrality targets has intensified the demand for lithium-ion batteries (LIBs) with high energy density. While the innovation of cathode/anode active materials has reached a plateau, development of thick electrodes has emerged as a critical breakthrough to achieving high-energy-density LIBs. However, the conventional wet coating process has intrinsic limitations, such as binder migration during the solvent drying process, which becomes increasingly problematic with thick electrodes. To address these challenges, dry coating processes have been actively explored in three main forms: electrostatic spraying, hot pressing with thermoplastic polymers,…
