Abstract

Solving intrinsic structural problems such as low conductivity is the main challenge to promote the commercial application of Li2TiSiO5. In this study, Li2TiSiO5 is synthesized by the sol-gel method, and the surface modification of Li2TiSiO5 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 Li2TiSiO5 is shifted to a lower angle, and the shift angle increases with increasing sputtering power. Li2TiSiO5 after 300 W bombardment shows excellent capacity (144.7 mA·hg−1 after 500 cycles at 0.1 Ag−1) and rate performance (140 mA·hg−1 at 5 Ag−1). Electrochemical analysis indicates that excellent electrochemical performance is attributed to the enhancement of electronic and ionic conductivity by plasma bombardment.
