Cubic mono-dispersion LiNi0.8Co0.1Mn0.1O2 micrometer particles synthesized by co-precipitation method exhibit enhanced structural stability and cycling performance compared to conventional spherical and irregular mono-dispersion LiNi0.8Co0.1Mn0.1O2.
LiNi0.8Co0.1Mn0.1O2 cathode material for lithium-ion battery exhibits high capacity, but it suffers from interfacial side reactions and structural/Ni0.8Co0.1Mn0.1)C2O4 center dot 2H(2)O particles with micron size are synthesized by co-precipitation method. The oxalic precursor is sintered with lithium hydroxide to obtain cubic mono-dispersion LiNi0.8Co0.1Mn0.1O2 micrometer particles. Structural stability, cycling performance, rate capability and compacting density of the cubic mono-dispersion material are investigated. Conventional spherical and irregular mono-dispersion LiNi0.8Co0.1Mn0.1O2 are also prepared for comparison. The results reveal that the cubic mono-dispersion LiNi0.8Co0.1Mn0.1O2 dramatically enhances the structural stability and cycling performance at a little cost of capacity and rate capability.
