Abstract
Electrode materials with tailored shapes for one-dimensional (ID) nanorods were manufactured using
a solvothermal approach. Different conditions led to the formation of samples with diverse
morphologies and compositions. Structural characteristics were studied using XRD, FT-IR, EDX, FE-SEM,
TEM and BET analysis (NH4)2V6O16 and (NH4)2V10O25$8H2O structures were obtained under these
conditions. The charge–discharge test was conducted to compare the activity of electrode materials
with different phase purities. After 15 cycles at a current density of 1 mA, the fabricated
(NH4)2V10O25$8H2O material displayed a capacity of 956 mA h g−1
, and a maximum capacity of
5268 mA h g−1 was obtained at the 7th cycle. However, the (NH4)2V6O16 electrode material showed
324 mA h g−1 capacity. Vanadium-based materials have poor conductivity. Therefore, designing 1D
structures improves the hydrogen storage efficiency of the electrodes. The optimized sample with
a nanorod structure and (NH4)2V10O25$8H2O phase purity shows a surface area of 23.571 m2 g−1
