Abstract

In this paper, the structural properties and electrochemical performances of CaCO3 coated LiNi0.8Co0.1Mn0.1O2 cathode is investigated for next generation high-energy lithium-ion battery. The crystallinity and microstructure of the samples are measured via XRD, SEM and TEM. The thickness of thin and uniform coating layer is approximately 30.1 nm. The initial discharge capacity and capacity retention of CaCO3 coated LiNi0.8Co0.1Mn0.1O2 cathode are 197.3 mAh g-1 and 83.1 % after 70 cycles, respectively, superior performances as compared to pristine LiNi0.8Co0.1Mn0.1O2. The CaCO3 coating layer can reduce the Ni dissolution, lowering resistance between electrolyte and cathode
