NH4F has been used to precipitate the lithium residue on surface of LiNi0.8Co0.1Mn0.1O2 and the in-situ precipitated LiF works as HF inhibitor during cycling, thus LiF-modified LiNi0.8Co0.1Mn0.1O2 exhibits noticeably enhanced rate capability and cycling performance compared with the pristine materia...
