主 题:Cu pro cycle Lithium Storage Property of Graphite/AlCuFe Quasicrystal Composites Graphite
摘 要:Quasicrystals have long-range quasi-periodic translational ordering and non-crystallographic rotational ***-Cu-Fe quasicrystals have great potential for lithium storage because of their high Al content and a large number of defects in the *** our previous study(*** Compd.805(2019)942)we showed that Al-Cu-Fe quasicrystals have good initial capacity whereas its cycle stability is *** the present study,graphite/AlCuFe is prepared by the mechanical alloying *** results show that graphite/AlCuFe quasicrystal composites are successfully synthesized by planetary ball milling at 550 rpm for 80 *** quasicrystal particle size decreases and the amorphous graphite forms onion-like carbon(OLC)when the two phases mix *** forms on the surface of the Al-Cu-Fe quasicrystalline *** and discharge tests show that graphite/AlCuFe quasicrystal composites have high-stability capacity of 480 mAh/g after 20 cycles,which is larger than the sum of capacities of graphite and Al-Cu-Fe quasicrystals.
