据报道，Li+嵌入TiO 2-B纳米线的组合物高达Li 0.91 TiO 2-B（比电荷容量：305 mA h g（-1）），并且具有比纳米颗粒和块状TiO 2-B上级的倍率性能（见图）。Li+嵌入的高容量、高倍率能力和类似于1.6V的电势的组合使得嵌入的纳米线作为可再充电锂电池的阳极和超级电容器的负电极令人感兴趣。
Li+ Intercalation into TiO2-B nanowires is reported up to a composition of Li0.91TiO2-B (specific charge capacity: 305 mA h g(-1)) and with a superior rate capability to nanoparticulate anatase and bulk TiO2-B (see Figure). The combination of high capacity for Li+ intercalation, high rate capability, and a potential of similar to 1.6 V, renders the intercalated nanowires interesting as anodes for rechargeable lithium batteries and negative electrodes for supercapacitors.
