Li2ZnTi3O8 (LZTO) and
reduced graphite oxide modified Li2ZnTi3O8
which are designated as LZTO@RGO10, LZTO@RGO25 and LZTO@RGO50 anodes were
successfully prepared by a facile and cost effective ball mill assisted solid
state method. RGO/LZTO mass ratios were selected as 0.1: 1, 0.25:1 and 0.5:1,
respectively. The effects of RGO
content on the crystal lattice, particle morphology and electrochemical
properties were investigated. The electrochemical performance of LZTO could be
improved by adjusting the content of RGO.
Among all the samples, LZTO@RGO25 exhibits excellent electrochemical
performance in terms of high capacities (302, 250, 221, 194 and 154 mAh g-1
at current densities of 0.1, 0.5, 1, 2 and 5C, respectively). Cycling
performance measurements show that , LZTO@RGO25 has 200 mAh g-1 residual capacity
compared with that (66 mAh g-1) of LZTO after 100 cycles at 1C rate.
