【 摘 要 】

3-Dimensionally ordered macroporous LiMn₂O₄ thin film was prepared by a sol-gel and dip coating method on Pt/Ti/SiO₂/Si substrate. An opal structure consisting of mono dispersed polystyrene beads (300 nm) was used as a template. After solution containing Mn and Li precursors was coated on the template-deposited substrate, the template and organic materials in the precursors was removed by calcination at 400�?. And then the 3-dimensional LiMn₂O₄ thin film with spinel structure was fabricated by heat treatment at 700�?. The structural and electrochemical property was investigated by XRD, SEM and charge-discharge cycler.
