摘要: Abstract In this study, we initially report the effect of lithium cobalt oxide (LiCoO2) doped with different Ni ion contents on dielectric and microwave absorption properties. Pure phases LiCoxNi1−xO2 (x = 0.2, 0.4, 0.6 0.8) have been synthesized using a solid-state reaction. Both permittivity permeability values composites distinctly shifted increasing Ni-doping content. The result indicates that LiCo0.4Ni0.6O2 composite exhibits appropriate permittivity, which can be attributed to distribution distortion lattice volume. Further, eʹ eʹʹ are 3.5 35 times higher than LiCo0.8Ni0.2O2 composite. minimum reflection loss wide band obtained by calculating various compositions (x) thicknesses. optimum value is −46 dB thickness 2.6 mm at 8.63 GHz, absorber bandwidth (RL
