ABSTRACT = {Solving intrinsic structural problems such as low conductivity is the main challenge to promote the commercial application of Li<sub>2</sub>TiSiO<sub>5</sub>. In this study, Li<sub>2</sub>TiSiO<sub>5</sub> is synthesized by the sol-gel method, and the surface modification of Li<sub>2</sub>TiSiO<sub>5</sub> is carried out at different temperatures using low-temperature plasma to enhance its lithium storage performance. The morphological structure and electrochemical tests demonstrate that plasma treatment can improve the degree of agglomeration. The peak position of the plasma-treated Li<sub>2</sub>TiSiO<sub>5</sub> is shifted to a lower angle, and the shift angle increases with increasing sputtering power. Li<sub>2</sub>TiSiO<sub>5</sub> after 300 W bombardment shows excellent capacity (144.7 mA·hg<sup>−1</sup> after 500 cycles at 0.1 Ag<sup>−1</sup>) and rate performance (140 mA·hg<sup>−1</sup> at 5 Ag<sup>−1</sup>). Electrochemical analysis indicates that excellent electrochemical performance is attributed to the enhancement of electronic and ionic conductivity by plasma bombardment.},
