Abstract

Polyanionic LiTi₂(PO₄)₃ material with 3D framework structure is intensively investigated to be used in lithium ion batteries. However, the LiTi₂(PO₄)₃-based materials suffer from poor electronic conductivity hindering the application as electrode active materials. This work describes an effective and simple strategy to synthesize LiTi₂(PO₄)₃/C core–shell structure without the addition of external carbon sources. This approach is achieved by a simple one-step solid state reaction using organometallic salt as raw material. The as-prepared LiTi₂(PO₄)₃ exhibits uniform and thin carbon coating on the particle surface. The electrochemical properties of the LiTi₂(PO₄)₃/C composite are investigated, and the results demonstrate that the as-prepared LiTi₂(PO₄)₃/C shows good cycling performance and rate capability.
