摘要

This work develops a fluorinated block copolymer electrolyte that disrupts poly(

-caprolactone) (PCL) crystallinity to enhance ion transport and

in situ

forms a LiF-rich solid electrolyte interphase (SEI) for stable lithium metal cycling.

Abstract

The practical deployment of polyester-based solid electrolytes such as poly(

-caprolactone) (PCL) is hindered by two inherent material-level constraints: the semicrystalline nature of PCL chains severely restricts segmental mobility and limits ionic conductivity

whereas interfacial instability against lithium metal anodes jeopardizes long-term cycling. Based on orthogonal polymerization technology combined with electrolyte structural design concepts

this work achieved a one-step fabrication of a polyester-based block copolymer electrolyte (BCPE) system comprising fluorinated segments (PTFEA) and poly(

-caprolactone) (PCL). Structurally

this design enables a dual breakthrough in electrochemical performance: on one hand

the introduction of fluorinated segments with steric hindrance effects can effectively disrupt the regular arrangement of the PCL main chain

reduce the crystallinity of PCL within the polymer electrolyte

and significantly enhance the segmental mobility of the polymer matrix; on the other hand

during the charge/discharge cycles of lithium batteries

fluorinated segments can induce the formation of a LiF-rich solid electrolyte interphase (SEI) through

in situ

decomposition reactions

achieving interface stabilization and homogeneous lithium-ion deposition regulation.
