摘要：

Li1.5Al0.5Ge1.5(PO4)(3) (LAGP) with a NASICON (LiM2(PO4)(3)) structure has been successfully prepared using solid-state reaction. Structural characterization shows LiM2(PO4)(3) to be the main phase. The total conductivity of the as-prepared LAGP is about 3.5 x 10(-6) S/cm with an electrical conductivity of 10(-9) S/cm Electrochemical study reveals that the LAGP is stable up to 7 V with a slight reduction at about 0.85 V (vs Li/Li+). For the first time, the electrochemical performance of the LAGP as an anode for lithium battery is tested, showing that the LAGP could be used as an anode material with good cycleability (C) 2010 Elsevier B V All rights reserved
