ABSTRACT:Abstract(#br)Due to its high theoretical capacity and stable structure, Na 3 V 2 (PO 4 ) 3 has gained much attention as a potential cathode for sodium-ion batteries (SIBs) in large-scale energy storage applications. However, poor electronic conductivity usually results in the low rate capacity and poor cyclability, limiting its application. Herein, we successfully introduce Fe 3+ to substitute V 3+ through doping engineering. Compared with Na 3 V 2 (PO 4 ) 3 /C, an excellent initial high-rate ca... 更多
