文摘
- •
VDF based copolymers are used as multi-functional binders for lithium–sulfur batteries.
- •
P(VDF-TRFE) binder exhibits higher adhesion strength, less porosity, and stronger affinity to polysulfides.
- •
P(VDF-TRFE) binder could enhance the electrochemical performance of lithium–sulfur batteries.
