摘要：
A simple method for the synthesis of niobium pyrophosphate NbP1.8O7 using polymer was proposed. A polymer-assisted one-step calcination was used to prepare pure-phase niobium pyrophosphate by regulating the addition amount of phosphorus-containing polymer. The calcination heating rate was adjusted to further improve the amorphization of the anode material. Then the electrochemical performance of the electrode material was investigated. The results show that the optimized electrode materials present excellent electrochemical sodium storage performance. Niobium pyrophosphate tends to be more amorphous at temperature rise rate of 5 ℃ / min and exhibits better electrochemical performance. It has a reversible discharge capacity of 164. 6 and 101. 37 mA·h/ g after 5000 cycles at a current density of 1000 mA/ g and 2000 mA/ g. © 2024 University of Petroleum, China. All rights reserved.
