Researchers identify new class of non-flammable electrolytes for Li-ion batteries

Green Car Congress

Balsara at UC Berkeley, have identified a new class of nonflammable electrolytes based on functionalized perfluoropolyethers (PFPEs) for lithium-ion batteries. In addition to being nonflammable, PFPE exhibits very interesting properties such as its ion transport. That makes this electrolyte stand apart from previous discoveries.
