New phosphate based composition, LiNi4(PO4) has been synthesized by sol-gel method and characterized by powder X-ray diffraction, scanning electron microscope and infrared techniques. This compound crystallizes in the monoclinic lattice. Cole�Cole plot was obtained from the impedance data and a maximum conductivity of 3.5 � 10�6 S cm�1 was obtained at room temperature  . The electrochemical properties were analyzed by cyclic voltammetry between 2 and 3.5 V vs. Li/Li+. Galvanostatic discharge�charge experiments were carried out between 1.5 and 4.2 V.
