Ultra-stable carbon-coated sodium vanadium phosphate as cathode material for sodium-ion battery
文献摘要：
Based on the excellent sodium ion mobility of sodium superionic conductor structures,Na3V2(PO4)3 materials have become promising cathode materials in sodium-ion batteries (SIBs).However,inadequate elec-tronic transport of Na3V2(PO4)3 limits the cycling stability and rate performances in SIBs.In this work,high-perfor-mance conductive carbon-coated Na3V2(PO4)3 materials are obtained via a simple and facile ball-milling assisted solid-state method by utilizing citric acid as carbon sour-ces.The carbon-coated composite electrodes display a high initial specific capacity of 111.6 mAh·g-1,and the specific capacity could retention reach 92.83％ after 100 cycles at 1C with the high coulombic efficiency (99.95％).More importantly,the capacity of conductive carbon-coated nano-sized Na3V2(PO4)3 can remain 48.5 mAh·g-1 at 10C after 3000 cycles (initial capacity of 101.2 mAh·g-1).At the same time,high coulombic efficiency (near 100％) has little decay even at a high rate of 20C during 1000 cycles,demonstrating the excellent cycling stability and remark-able rate performances,and showing potential in large-scale productions and applications.
