In situ-fabricated quasi-solid polymer electrolytes incorporating an ionic liquid for flexible supercapacitors

Abstract

A quasi-solid polymer electrolyte is fabricated by an in situ polymerization of PEGDMA in AN solvent based on a thermal initiation mechanism and incorporating the ionic liquid EMITFSI for application in flexible supercapacitors.

Gradient-integrated bilayer solid polymer electrolyte enabling enhanced room-temperature cyclability for rechargeable lithium metal batteries

“…34 Especially, a prominent B–F peak and weak B–O peak were observed in the B 1s spectrum, indicating that LiODFB is involved in the formation of a passivation film on the cathode. 35–37 Consequently, the construction of an F, N, B-rich interface due to the cooperative contribution of the PVDF matrix, IL and LiODFB minimizes the side reactions at the cathode/electrolyte interface and preserves the integrity of the cathode structure, 38 enhancing the reversible capacity and lifespan of the LMBs.…”
