An initiator loaded separator triggering in situ polymerization of a poly(1,3-dioxolane) quasi-solid electrolyte for lithium metal batteries

“…Furthermore, there is a red shift regarding the C–O–C vibration mode (1022 cm −1 ) and the presence of the vibration mode from long-chain C–C (845 cm −1 ) for all of polymerized samples. 40–42 This result provides clear evidence that in situ polymerization of DOL is achieved. Additionally, Raman spectra shown in Fig.…”
