Induction Effect of Fluorine-Grafted Polymer-Based Electrolytes for High-Performance Lithium Metal Batteries (IMAGE)
Caption
- luorine-grafted quasi-solid-state composite electrolyte (F-QSCE)@30 exhibits high ionic conductivity of 1.21 mS cm–1 at 25 °C.
- The inductive effect weakens the coordination between Li+ and TFSI‒, enhancing Li+ transport.
- LiF in the solid electrolyte interphase of F-QSCE@30 comes from decomposed F segments, not TFSI‒.
- F-QSCE@30 maintains stability with Li metal for over 4000 h and inhibits dendrite growth.
