Abstract
Brookite TiO2 mesocrystals were synthesized for the first time using amorphous titanate used as a precursor, exhibiting a high rate capability when applied as an anode for lithium-ion batteries. An in situ X-ray diffraction test of lithium intercalation into the brookite TiO2 structure was further investigated and revealed a reversible phase transformation.
摘要
首次使用无定形钛酸盐作为前驱体制备了锐钛矿 TiO2 介晶，将其用作锂离子电池的阳极时表现出高倍率性能。进一步对锂离子嵌入锐钛矿 TiO2 结构的原位 X 射线衍射测试进行了研究，揭示了其可逆的相变过程。
