摘要:
Li-rich layered Li2MnO3 is of great attraction for high energy lithium ion batteries. However, its cycling is still needed for improvements. Here we report a hollow microsphere-structured xLi(2)MnO(3)center dot(1-x)LiNiO2 (x = 0.3-0.7) that is synthesized by using in-situ template-sacrificial strategy. Powder X-ray diffraction (XRD) and scanning electron microscope (SEM) characterizations prove that thexLi(2)MnO(3)center dot(1-x)LiNiO2 (x = 0.3-0.7) are based on monoclinic Li2MnO3 with alpha-NaFeO2 layered structure in which Li+ ions are orderly arranged in the transition metal layers, and the...
