Why it matters

Now, a study, published in the Journal of the American Chemical Society, reports on a new method that improves the way plasticizers work with poly(vinylidene fluoride) (PVDF) in the electrolytes of lithium batteries, further improving performance and safety.

Common ground

The plasticizer compatibility–stability trade-off Polymer electrolytes are attractive for their stability and processability, but face challenges with interfacial instability.
