Abstract

Li2ZnTi3O8/TiO2 composite anode materials were synthesized by using a one-pot co-precipitation method for the first time. Texture characteristic and electrochemical measurements were taken of this composite and of pure as-prepared Li2ZnTi3O8 to investigate their structures, morphologies and electrochemical properties. The Li2ZnTi3O8/TiO2 composite anode material showed a better cycle performance and a higher rate performance than did the pure Li2ZnTi3O8. At current densities of 1000 mA g−1, 2000 mA g−1 and 3000 mA g−1, the dual-phased Li2ZnTi3O8/TiO2 composite yielded discharge capacities, respectively, of 211.1 mA h g−1, 199.8 mA h g−1 and 180.8 mA h g−1 at the first cycle, and 150.6 mA h g−1, 137.2 mA h g−1 and 108.2 mA h g−1, respectively, after 1000 cycles. The high specific capacity together with outstanding rate and cycle performance of the Li2ZnTi3O8/TiO2 composite suggest it to be a promising anode material for lithium ion batteries.
