Abstract

We report on the Na-insertion/extraction properties of NASICON type carbon-coated LiTi₂(PO₄)₃ (C-LiTi ₂(PO₄)₃) in aqueous medium. Sub-micron sized LiTi₂(PO₄)₃ particles are synthesized by a pechini type polymerizable complex method and subsequently coated with carbon. Na-insertion properties are evaluated in a three electrode configuration and it was found that ∼1.32 mol of Na (capacity of ∼91 mA h g^-1) could be reversibly inserted/extracted at 1 C rate. High power capability of C-LiTi₂(PO₄)₃ is also demonstrated with good capacity retention characteristics.
