主 题:Organic anode material Low redox potential Composite anode Sodium-ion batteries
摘 要:Sodium-ion batteries (SIBs) with organic electrodes are an emerging research direction due to the sustainability of organic materials based on elements like C,H,O,and sodium ***,organic electrode materials for SIBs are mainly used as cathodes because of their relatively high redox potentials(1 V).Organic electrodes with low redox potential that can be used as anode are ***,a novel organic anode material (tetrasodium 1,4,5,8-naphthalenetetracarboxylate,Na4TDC) has been developed with low redox potential (0.7 V) and excellent cyclic *** three-sodium storage mechanism was demonstrated with various in-situ/ex-situ spectroscopy and theoretical calculations,showing a high capacity of 208 mAh/g and an average decay rate of merely 0.022%per ***,the Na4TDC-hard carbon composite can further acquire improved capacity and cycling stability for 1200 cycles even with a high mass loading of up to 20 mg *** pairing with a thick Na3V2(PO4)3cathode (20.6 mg cm-2),the as-fabricated full cell exhibited high operating voltage (2.8 V),excellent rate performance and cycling stability with a high capacity retention of 88.7% after 200 cycles,well highlighting the Na4TDC anode material for SIBs.
