【Abstract】 The polyanionic compound lithium titanium phosphate [LiTi₂（PO₄）₃] of NASICON structure has attracted extensive attention due to its stable three-dimensional structure, high ionic conductivity(2.0 × 10^-6S/cm), stable operating voltage. Researchers have applied it to the anode material of aqueous and the coating layer of lithium-ion batteries, but the poor electronic conductivity of LiTi₂（PO₄）₃restricts the development of the material. Thus, the structure and properties, preparation methods and modification methods with poor conductivity of LiTi₂（PO₄）₃was summarized, and the development direction of LiTi₂（PO₄）₃materials was forecasted.更多还原
