Metal silicates are good candidates for use in lithium ion batteries (LIBs), however, their electrochemical performance is hindered by their poor electrical conductivity and volume expansion during Li⁺ insertion/desertion. In this work, one-dimensional core–shell structured MnSiO₃ supported with carbon nanotubes (CNTs) (referred to as CNT@MnSiO₃) with good conductivity and electrochemical performance has been successfully synthesized using a solvothermal process under moderate conditions. In contrast to traditional composites of CNTs and nanoparticles, the CNT@MnSiO₃ composite in this work is made up of CNTs with a layer of MnSiO₃ on the surface. The one-dimensional CNT@MnSiO₃ nanotubes provide a useful channel for transferring Li⁺ ions during the discharge/charge process, which accelerates the Li⁺ diffusion speed. The CNTs inside the structure not only enhance the conductivity of the composite, but also prevent volume expansion. A high reversible capacity (920 mA h g⁻¹ at 500 mA g⁻¹ over 650 cycles) and good rate performance were obtained for CNT@MnSiO₃, showing that this strategy of synthesizing coaxial CNT@MnSiO₃ nanotubes offers a promising method for preparing other silicates for LIBs or other applications.
