Abstract

The optimal conditions for the synthesis of Na4Nb8P4O32 were found and the phase composition, morphology and electrochemical properties were studied in this work. The effect of the temperature and the synthesis time on the phase composition of Na4Nb8P4O32 were shown. According to the X-ray phase analysis data the optimal synthesis conditions were 900°C and 2.5 hours. The values of ionic and electronic conductivity were 2.7 · 10−7 S/cm and 6.1 · 10−6 S/cm, respectively. The obtained values of the charge and discharge capacities were 43 mA·h/g and 44 mA·h/g, respectively.
