摘要：

Three dimensionally ordered macroporous membrane of a Li-ion conductive ceramic, Li-La-Ti-O (LLT), for all solid-state rechargeable lithium battery was prepared using colloidal templating process combined with sol-gel method. An opal structure consisting of mono-dispersed polystyrene beads (470 nm in diameter) was used as a template. The preparation conditions of LLT membrane were optimized to obtain a relatively large size porous membrane. The LLT calcinated at 600 degrees C was amorphous, and its Li-ion conductivity was 10(-5) S cm(-1) at room temperature. The composite electrodes of LLT-Li4Ti5O12 and LLT-LiMn2O4 were successfully prepared by sol-gel process. (c) 2005 Elsevier B.V. All rights reserved.
