Constructing LiF-rich cathode electrolyte interphase to enhance the cyclic stability of lithium-rich manganese-based oxide cathode

Abstract

Lithium-rich manganese-based oxide (LRMO) materials hold great potential for high-energy-density lithium-ion batteries (LIBs) but suffer from severe voltage decay and capacity fading. Herein, we report the in situ construction of LiF-rich solid electrolyte interphase on LRMO through a straightforward ball-milling and electrochemical approach, which exhibits remarkable structural stability and enhanced electrochemical performance.
