Effect of Operational Synthesis Parameters on the Morphology and the Electrochemical Properties of 3D Hierarchical AlV3O9 Architectures for Li-Ion Batteries

Novel generation rechargeable battery technology awaits advanced materials with stable structures and special construction in order to have control over side reactions and provide a well-balanced set of physicochemical interactions to store electrochemical energy. Here, we synthesize various morphology and size of AlV3O9 structures (AV) via a simple hydrothermal method. The high specific capacity for flower-like, rod-like and polygon spheres are 233, 317 and 278.5 mAh g(-1) respectively. Also, urchin-like AlV3O9 as optimum electrode deliveries discharge capacities 294.65 mAh g(-1) (as cathode) and 609.09 mAh g(-1) (as anode) at the current rate of 0.1 C, which leads to capacity maintenance of 99.79% after 100 round cycles at a 1 C current rate with excellent rate capacity. We opine that the framework of this research arranges a principle of fabrication for electrochemically appropriate constructions, which is of excellent potential and function for progressing battery storage efficiency by modifying the structure and morphology of AlV3O9 materials on multidimensional structures.
