The current lithium-ion battery (LIB) electrode fabrication process relies heavily on the wet coating process, which uses the environmentally harmful and toxic N-methyl-2-pyrrolidone (NMP) solvent.
Venjakob, a specialist in coating lines, and Plasmatreat, a manufacturer of atmospheric plasma technology, have developed a contact-free protective coating process for battery cells. Instead of using film wrapping, battery cells are coated with a protective layer applied in a continuous process. This method ensures comprehensive protection.
Here, we will discuss some of the innovative researches on the manufacturing processes for LIB production, mainly focusing on mixing, coating, drying, solvent recovery, calendering, slitting, and formation and aging. Other steps including stacking and enclosing are very mature, and not much research has been done on these steps.
