Na2TiSiO5 is investigated as a novel anode of the lithium ion battery for the first time. The low working potential (above 0.1 V) and high capacity (>300 mA h g-1) give this material a high energy density, along with improved safety. After 100 cycles, the capacity retention remains at 94%. Furthermore, possible Li+-occupied sites and the migration path in the Na2TiSiO5 structure are also calculated and discussed in this work.
Na2TiSiO5 是首次被研究作为锂离子电池的新型阳极。该材料具有较低的工作电位（高于 0.1 V）和较高的容量（>300 mA h g-1），这使其具有较高的能量密度，同时提高了安全性。经过 100 次循环后，容量保持率仍保持在 94%。此外，本工作还计算并讨论了 Na2TiSiO5 结构中可能的 Li+占据位置和迁移路径。
