摘要：

A novel electrode system composed of three-dimensionally ordered macroporous (3DOM) Li1.5Al0.5Ti1.5(PO4)(3) (LATP) and LiMn2O4 was fabricated by the colloidal crystal templating method and sol-gel process. A LATP nanoparticle for the fabrication of 3DOM-LATP was prepared by a sol-gel process. A suspension containing polystyrene (PS) beads and the LATP nanoparticles was filtrated by using a polycarbonate filter to accumulate PS beads and LATP. The accumulated PS beads had a close-packing structure, and the void between PS beads was filled with LATP nanoparticles. 3DOM-LATP was obtained by heat treatment of the accumulated composite. Li-Mn-O sol was injected by a vacuum impregnation process into the macropores of 3DOM-LATP and then was heated to form three-dimensionally ordered composite materials consisting of LiMn2O4 and LATP. The formation of the composite between 3DOM-LATP and LiMn2O4 were confirmed with scanning electron microscopy and X-ray diffraction method. The prepared composite electrode system exhibited a good electrochemical performance.
