In this work, Fe2O3 nanooval is successfully synthesized with variation of glycine composition of 9, 12, and 15 mmol at hydrothermal temperature of 160 °C. The Fe2O3 nanooval is indexed by XRD as α-Fe2O3. SEM and TEM images show that the 12 mmol of glycine has the largest diameter with the perfect nanooval form. Nyquist plot shows that the 12 mmol of glycine sample has the best conductivity value of 8.26x10-5 S/m. The CV of sample 12 mmol delivers the best intercalate/de-intercalate with ΔV of 0.82 V. The 12 mmol sample shows the largest specific discharge capacity of 631.62 mAh/g. It is attributed to high conductivity and high kinetics reaction of Li ion during charge-discharge process. Therefore, Fe2O3 nanooval is a promising candidate as anode for lithium-ion battery.

A facile technique was used to prepare self-assembled 3D urchin-like V2O5 under solvothermal condition. The 3D urchin-like V2O5 could provide high Li[Formula: see text] capacity with excellent rate performance, presenting a high reversible discharge capacity of 271.6[Formula: see text]mAh[Formula: see text]g[Formula: see text], at 0.1[Formula: see text]C. At current density of 1[Formula: see text]C, it shows a high reversible capacities of 209[Formula: see text]mAh[Formula: see text]g[Formula: see text] with capactity retention of 91.8% (191[Formula: see text]mAh[Formula: see text]g[Formula: see text]) after 380 cycles. Even at 2[Formula: see text]C and 5[Formula: see text]C, the capacity displays 172.4 and 129.24[Formula: see text]mAh[Formula: see text]g[Formula: see text]. The above enhanced performance is caused from greatly enhanced charge transportation, which closely relates to the structural stability and more channels for Li[Formula: see text] transfer of the unique 3D urchin-like V2O5.

The Sn-Ge metal composite powder was obtained by reduction of the SnGeO3. The XRD and SEM analysis of Sn-Ge were completed. The simulation battery was prepared by using the Sn-Ge as lithium ion battery anode material, and its electrochemical properties were characterized. The results indicate that the SnGeO3 was reduced at 723K to generate the Sn-Ge composite powder instead of the alloy. The first embedding lithium capacity (discharge capacity) was 625 mAh·g-1, the first taking off lithium capacity (charge capacity) was 590 mAh·g-1 for the simulation battery. The capacity gradually decreased with the charge-discharge cycle number increasing, and the discharge capacity corresponded to 88% of the initial discharge capacity, and the charge capacity corresponded to 89% of the initial charge capacity at 20th week. The Sn-Ge composite powder can be used as the lithium ion battery anode material due to possessing embedding / taking off lithium capacity.
