Herein, porous Li₄Ti₅O₁₂ has been prepared by a facile sol-gel process with poly(ethylene oxide) used as a phase separation inducer, which presents a novel micro/nano structure with micro-sized secondary structure (2–5 μm) constructed by many interconnected nano-sized primary components (30–60 nm). As an anode material for lithium ion batteries, the as-prepared Li₄Ti₅O₁₂ exhibits good cycling stability and rate capability, which could be attributed to the unique porous micro/nano structure.

微/纳米结构Li ₄ Ti ₅ O ₁₂作为锂离子电池的高倍率负极材料

本文中，多孔聚Li ₄ Ti ₅ O ₁₂是通过一种简便的溶胶-凝胶法制备的，其中聚环氧乙烷用作相分离诱导剂，呈现出具有微米级二级结构的新型微/纳米结构（2–5 μm）由许多相互连接的纳米级主要成分（30–60 nm）构成。作为锂离子电池的负极材料，所制备的Li ₄ Ti ₅ O ₁₂具有良好的循环稳定性和倍率性能，这可以归因于独特的多孔微/纳米结构。
