Abstract: Chiral sodium zinc phosphate was prepared by solid state method.The X-ray diffraction(XRD) pattern and trans- mission electron microscope(TEM) images revealed that as-prepared sample was porous structure of chiral sodium zinc phosphate which belonged to hexagonal system and P6122 space group.The electrochemical properties showed that synthe- sized sodium zinc phosphate had excellent electrochemical reaction activity,and the oxidation peak was basic anastomotic with the reduction peek after many times′cycles.With the increase of cycling times,the discharge voltage increase gradually and the capacity remain 170 mA·h/g after 100 cycles.The excellent electrochemical stability is mainly attributed to the porous structure of sodium zinc phosphate,which increased the effective area of electrode reaction and reduced the electrode polarization.
