Sol–Gel Synthesis and Electrochemical Studies on Mo3Nb2O14

Abstract

Shear ReO3 structure type Mo3Nb2O14 was prepared by both solid state reaction, sol–gel methods, characterized by Powder X-ray Diffraction Patterns (PXRD) and compared the electrochemical cycling performance. Ex-situ XRD studies proved that the structure is retained. Sol–gel sample shows high capacity 175 mAhg−1 after 20 cycles. At C/5 rate, Sol–gel sample shows lower capacity fading 243 mAhg−1, when compared with solid state reaction sample 170 mAhg−1 after 20 cycles. Mo3Nb2O14 shows good cycling behavior. The complete outcome will be discussed based on the charge/discharge cycles.
