Abstract Spherical Ni 0.6 Co 0.2 Mn 0.2 (OH) 2 precursor with the concentration of Ni and Mn changed in opposite was prepared by co-precipitation. Then, well-ordered spherical LiNi 0.6 Co 0.2 Mn 0.2 O 2 was synthesized by sintering the mixture of as-prepared precursor and LiOH⋅H 2 O first calcined at 550 °C for 4 h in air, followed at 820 °C for 12

Abstract As attractive materials for the power sources with high energy density, high-nickel electrode materials are limited by cyclability and safety problems for extensive applications. In order to improve the performance of LiNi0.6Co0.2Mn0.2O2 (NCM622), aluminium phosphate (AlPO4) modification was adopted via a facile approach.

Abstract Homogenous nanoscale LiNi 0.6 Co 0.2 Mn 0.2 O 2 (NCM) cathode material powder was successfully synthesized by the ultrasonic-assisted co-precipitation (UC) method. Compared with traditional co-precipitation (TC) method, the obtained NCM by UC method has better layered structure and lower level of cation mixing, which is confirmed by the XRD

Abstract Interfacial stability is regarded as one of the greatest challenges in the commercialization of Ni-rich layered cathode materials, especially at high voltage. In this study, amorphous silica modified LiNi0.6Co0.2Mn0.2O2 cathode materials (NCM622) are successfully prepared by chemical grafting method using silane coupling agent (KH550).

Cycle life modeling and the capacity fading mechanisms in a graphite/LiNi0.6Co0.2Mn0.2O2 cell
Journal of Applied Electrochemistry, 2015A 3.0 Ah pouch-type lithium-ion cell with a high energy density (200 Wh kg−1) was studied to establish a cycle life model of the battery. The cells consisted of graphite and LiNi0.6Co0.2Mn0.2O2 electrodes, and they were cycled at 1 C over a 100 % depth of discharge at different temperatures (25, 35, and 45 °C).

Understanding the role of Mg-doped on core-shell structured layered oxide LiNi0.6Co0.2Mn0.2O2
Electrochimica Acta, 2019Abstract Mg-doped on core-shell structured layered oxide LiNi0.6Co0.2Mn0.2O2 cathodes are synthesized by doping Mg into LiNi0.8Co0.1Mn0.1O2 core and LiNi0.2Co0.4Mn0.4 O2 shell，respectively or Mg co-doped both in core and shell. The influence of Mg doping on crystal structure are characterized by XRD，EDS，XPS and ICP-ES. Electrochemical tests show that
