Alternatives to PFAS in LIBs
+ Talked to people from industry and academia + Focused on binder material and electrolyte
Binder 3 alternatives:
+ water-soluble polymeric binders + 3D nanocarbon binding structure
* binder-free technology
+ Unclear about large scale potential
N Prien
i4 Next generatiy on technologi"es
Electrolyte + PFAS salts at low concentrations improve
performance
+ LiPF, sufficient as main salt
+ Electrolyte composition depends on
performance requiemenis
. + Solid state batteries (e.g. fluoropolymers)

Conclusions
+ Encouragingthatso many alternativteos uses of PFAS already available and
transitions have occurred or happening + Challenges remain:
+ Unique propertiesof PFAS offering multiple functions
+ Some applications with no available alternatives currently available
+ Ensuring no regrettable substitutions (alternatives assessment)
* Resistance from some industries
+ Green energy transition being used as a "free pass" for derogations
.
+ Denyingthe problems with PFAS
Y
+ Claims that no altematives to PFAS when there clearly are
Sr
+ Adaption to new processes and materials likely costly and time consuming
: + PFAS restriction is an opportunity for innovation and for Europe to be world leaders
