Slot-die coating is actually the most used coating method for the manufacturing of lithium-ion battery electrodes. An easy way of reducing production costs is to increase the line capacity. Thus, the relatively high-viscous slurries are coated at continuously increasing velocities.
The aim of the electrode manufacturing process is to deposit onto a metallic current collector (typically aluminium for cathodes or copper for anodes), a dry (solvent …
Until now, the NCM series lithium-ion batteries have had a higher energy density []. However, the theoretical capacity of the graphite anode of commercial lithium-ion batteries is only 372 mAh g −1, which is far from being able to meet the demand for high-energy].
In order to reduce the cost of lithium-ion batteries, production scrap has to be minimized.
