摘      要：Sodium-ion batteries(SIBs)are considered one of the most promising energy storage systems for replacing lithium-ion batteries because of the high abundance and low cost of *** oxyfluoride(FeOF)is a promising conversion-based cathode material for SIBs because of its high theoretical capacity of about855 mA h g^(-1),low-cost chemical compositions,and its lower sensitivity to the size of charged carrier ***,the poor electrical conductivity and ionic diffusion of FeOF result in a low rate capability and *** this work,FeOF nanoparticles wrapped by graphitic carbon layers were synthesized using abietic or maleopimaric acid as both the carbon source and organic *** addition,the morphology of the FeOF particles was gradually controlled from rod to spherical shapes,simply depending on the rosin *** FeOF nanoparticles prepared with maleopimaric acid showed a large reversible discharge capacity of 356.7 mA h g^(-1)with a fading rate of 0.21%per cycle after 100 cycles at a current density of 100 mA g^(-1)and an excellent rate capability.
