Amorphous materials have many advantages over their crystalline states in transfering Li⁺ without restriction of defects, tolerating large volume change during the charging/discharging process and achieving a higher potential in lithium-ion batteries (LIBs). Crystalline LiTi₂(PO₄)₃/TiP₂O₇ nanoparticles embedded in porous CNTs were constructed firstly by sol-gel and calcination, in which sulfonated polymer nanotubes as both carbon source and template. Afterwards, amorphous (Li-)Ti-P-O nanoparticles embedded in porous CNTs were formed by electrochemical activation. Due to amorphous (Li-)Ti-P-O nanoparticles providing the multi-channel transport of Li⁺ and the porous carbon matrix preventing the gathering and pulverization of (Li-)Ti-P-O nanoparticles during the electrochemical process, (Li-)Ti-P-O/C hybrid nanotubes exhibit stable cyclic performances and good rate capacities (the capacities of Li-Ti-P-O/C and Ti-P-O/C hybrid nanotubes possess 388.9 and 457.2 mAh g^-1 at 0.2 A g^-1 after 500 cycles, and maintain 155.0 mAh g^-1 at 5 A g^-1 after 500 cycles and 123.3 mAh g^-1 at 5 A g^-1 after 3000 cycles, respectively). This paper provides a feasible method for the preparation of other anode materials with superior lithium storage performance.

非晶态材料在不限制缺陷的情况下转移Li ⁺，在充电/放电过程中可承受较大的体积变化以及在锂离子电池（LIB）中获得更高的电势方面具有优于晶态的许多优势。首先通过溶胶-凝胶法和煅烧法制备了嵌入多孔CNT中的结晶LiTi ₂（PO ₄）₃ / TiP ₂ O ₇纳米颗粒，其中磺化的聚合物纳米管既是碳源又是模板。然后，通过电化学活化形成嵌入多孔CNT中的无定形（Li-）Ti-PO纳米颗粒。由于无定形（Li-）Ti-PO纳米颗粒提供了Li ⁺的多通道传输并且多孔碳基体阻止了电化学过程中（Li-）Ti-PO纳米颗粒的聚集和粉碎，（Li-）Ti-PO / C杂化纳米管表现出稳定的循环性能和良好的倍率容量（Li-Ti的容量） -PO / C和Ti-PO / C杂化纳米管在500次循环后在0.2 A g ^-1时具有388.9和457.2 mAh g ^-1，在500次循环后在5 A g ^-1时保持155.0 mAh g ^-1和123.3 mAh g ^-1在5 A G ^-1后3000个循环，分别地）。本文提供了一种可行的方法来制备其他具有优异储锂性能的负极材料。
