摘要：

Two ceramic electrolytes, Li4Zr0.06Si0.94O4 and Li3.94Cr0.02Zr0.06Si0.94O4, were prepared by a citrate sol-gel method. The structure, morphology, particle size, conductivity and electrochemical property were investigated. Both electrolyte materials had quite similar lattice parameters. The Li3.94Cr0.02Zr0.06Si0.94O4 exhibited higher total conductivity value of 1.83 x 10(-4) S cm(-1) at an ambient temperature and 1.13 x 10(-3) S cm(-1) at 500 degrees C which are an order of magnitude higher than those of Li4Zr0.06Si0.94O4. Ionic transference number corresponding to Li+ ion transport was 0.92 for Li4Zr0.06Si0.94O4 and increased to 0.97 for Li3.94Cr0.02Zr0.06Si0.94O4. The Li3.94Cr0.02Zr0.06Si0.94O4 sample showed a maximum discharge capacity of 103 mAh g(-1) at the rate of 0.05 C in a potential range of 3.0-4.2 V. (C) 2013 Elsevier Ltd and Techna Group S.r.l.
