Zn2GeO4 Nanorods synthesized by low-temperature hydrothermal growth for high-capacity anode of lithium battery

Zinc germanate (Zn2GeO4) nanorods have been synthesized using a low-temperature hydrothermal method. The nanorods show a well-crystallized nanostructure with diameter in the range from 20 to 30 rim and length ranging from 100 to 150 nm. Electrochemical measurements demonstrate that the Zn2GeO4 electrodes retain a capacity of 616 mAh g(-1) after 100 cycles and possess excellent rate capability indicating that the Zn2GeO4 could be used as a candidate as high-capacity anode for lithium batteries.
