Charged EVs | Dürr unveils X.Cellify DC dry electrode coating system for battery manufacturing

Skinny has introduced the event of X.Cellify DC, a dry electrode coating course of that types a free-standing movie of lively battery materials, which is absolutely recyclable till it’s laminated onto the collector foil. The corporate says this method reduces lively materials waste in battery electrode manufacturing, and its proof-of-concept confirms the expertise’s reliability, scalability,and suitability for lithium-ion battery electrodes, with potential functions in solid-state battery manufacturing sooner or later.

Standard electrode manufacturing primarily makes use of moist coating, through which slurry is utilized to steel foils after which dried in an energy-intensive course of. X.Cellify DC replaces this with a solvent-free course of that makes use of a dry powder combination. The dry battery materials is pressed into a movie through the Activated Dry Electrode course of, equipped by growth companion LiCAP Applied sciences. The method levels embrace dosing, movie formation, densification and lamination onto the collector foil.

Dürr says that dry coating with X.Cellify DC gives notable course of benefits for battery manufacturing, together with reductions in required manufacturing area by as much as 65 p.c and power consumption by as much as 70 p.c. These financial savings are attributed to the elimination of drying ovens and solvent restoration methods.

The strategy additionally permits a closed loop for high quality management, because the free-standing movie might be recycled inside the manufacture line if it fails to satisfy specs, lowering scrap of lively supplies. The system’s net steerage design permits transport of the self-supporting movie and compacts it earlier than lamination onto the present collector.

“The profitable proof of idea is a serious step ahead for us. We have now demonstrated that the brand new type of dry coating with free-standing movie works reliably and delivers persistently good high quality. It may be scaled up, making it the premise for preliminary pilot tasks in business,” stated Bernhard Bruhn, Vice President of Dürr’s World Enterprise Unit LIB. “Since we don’t want a provider foil till the ultimate step, we are able to return the movie to the method in its entirety if it doesn’t meet the specified specs. Due to the closed loop, no beneficial lively materials is misplaced and we considerably cut back waste – an necessary level in battery manufacturing.”
