氟掺杂两亲性碳纳米片的微波强化制备及其锂金属电池性能
Microwave-enabled synthesis of fluorine-doped amphiphilic carbon nanosheets for improved lithium metal battery performance
摘要
Abstract
The extreme electronegativity of fluorine can change the intrinsic reactivity of carbon materials by reconstructing the carbon π-conjugation system through its electrons,which may have potential use in energy storage systems.However,high fluorine doping levels often lead to reduced surface polarity and electrolyte wettability,which limits their applicability.Herein,fluorine-doped carbon nanosheets with both a high fluorine content(6.10%,atomic percent)and amphiphilicity were fabricated from ethylene tar pitch by a novel microwave-assisted ionic liquid intensification strategy within a remarkably short time(20 min).During microwave treatment,the ionic liquid served as a heating medium,enabling a rapid temperature increase(100 ℃ min-1)through microwave absorption,thus ensuring efficient synthesis.When this material is used as a separator coating,the electrolyte wettability is much better.Meanwhile,the inherent covalent C―F bonds facilitate the formation of a LiF-rich solid electrolyte interphase layer upon lithiation,promoting uniform lithium deposition and suppressing dendrite growth as well as the formation of dead Li.The assembled lithium metal batteries had a high Coulombic efficiency retention(≥98.9%after 1200 cycles),ultra-long cycling stability(3400 h at 1 mA cm-2)and excellent full battery performance.This work suggests new ap-proaches to the synthesis and uses of novel fluorine-doped carbon materials.关键词
