Fluorinated DOL-based copolymer electrolytes enabling wide electrochemical window and stabilized interphases for lithium batteries

Employing a fluorinated copolymer strategy enhances performance by broadening Li + pathways to 7.3 × 10 −4 S cm −1 , enhancing stability beyond 5.9 V and 300 °C, and facilitating LiF-rich interphase formation.
