Abstract

In this study, a one-pot sintering process incorporating sol-gel preparation route and in-situ carbon coating was proposed for the synthesis of carbon-coated nanosized LiTi₂(PO₄)₃. Experimental results show that the prepared LiTi₂(PO₄)₃ particles are of high crystallinity and well-coated by turbostratic carbon. Attributed to nanosized particles and enhanced conductivity provided by turbostratic carbon coating, the carbon-coated LiTi₂(PO₄)₃ showed high rate performance and good cycling life in aqueous electrolyte. Particularly, the carbon-coated LiTi₂(PO₄)₃ exhibited initial specific capacities of 103 and 89 mAh g^-1, and retained 80.6% and 97% of the initial capacities after 120 cycles at 1C and 10C in aqueous electrolyte, respectively. The high rate performance and good cycling life of carbon-coated LiTi₂(PO₄)₃ in aqueous electrolyte reveal its potential as negative electrode in aqueous lithium-ion batteries for electric vehicles and industrial-scale energy storage systems.
