  In this paper, Al-Cu-Fe quasicrystal alloy was used as anode material of
lithium-ion batteries. The first specific discharge capacity of quasicrystal
was 204mAh/g. Cyclic voltammetry showed that oxidation peak of Al-Cu-Fe
quasicrystal was at about 1.4V. The reduction peak was at 0.3V. Al-Cu-Fe
quasicrystal have higher Li-ion diffusion impedance and Warburg in the first
cycle. X-ray diffraction analysis demonstrate that Li atom enter into
quasicrystal structure can not fully leave quasicrytal during first
charge/discharge cycle which induce the irreversible capacity.
