Weakly solvating electrolyte enables robust LiF-rich interphase to stabilize SnO2-based anode toward Li storage at low temperature

Key Points

• The robust LiF-rich interphase leads to enhanced lithium storage in SnO2-based anodes.
• Lithium storage capacity significantly increases at low temperatures with the weakly solvating electrolyte.
• Analysis using electrochemical techniques highlights the interphase stability from the electrolyte.
• Findings suggest improved low-temperature performance for lithium-ion battery applications.
