A Novel Double-shelled LiNi0.5Co0.2Mn0.3O2 Cathode Material for Li-ion Batteries

LiNi1−x−yCoxMnyO2 can be redesigned to double-shelled structure, which does not change total composition compared with some reported core–shell materials. In this paper, the spherical double-shelled Li[(Ni0.8Co0.1Mn0.1)2/7(Ni1/3Co1/3Mn1/3)3/14(Ni0.4Co0.2Mn0.4)1/2]O2 with total composition of LiNi0.5...

Zusammenfassung:LiNi1−x−yCoxMnyO2 can be redesigned to double-shelled structure, which does not change total composition compared with some reported core–shell materials. In this paper, the spherical double-shelled Li[(Ni0.8Co0.1Mn0.1)2/7(Ni1/3Co1/3Mn1/3)3/14(Ni0.4Co0.2Mn0.4)1/2]O2 with total composition of LiNi0.5Co0.2Mn0.3O2 was synthesized via a coprecipitation route for the first time. The double-shelled material displayed higher capacity, superior cycling performance, and thermal stability than the non-core–shell LiNi0.5Co0.2Mn0.3O2 material.
