Morphological Perspective on Energy Storage Behavior of Cobalt Vanadium Oxide
Abstract Currently available graphitic‐based anodes for lithium‐ion storage do not meet the present‐day energy requirements. Concerning the upcoming energy demands, it is necessary to discover high‐performance anode materials that are suitable for lithium‐ion energy storage systems. Herein, a CoV2 O6(cobalt vanadium oxide, cobalt vanadate denoted as CV) anode material using a simple solvothermal technique is synthesized. Furthermore, the effects of modifying the molar concentration of the precursor materials are investigated. Interestingly, there is no change in the crystal structure, but there is a morphological evolution in the materials. Due to the morphological variations, the electrochemical performances vary significantly. Among the synthesized materials, the CV‐2 compound performs the best, exhibiting excellent performance for lithium‐ion batteries as an anode. At the end of 500 cycles, the material delivers a specific discharge capacity of 391.03 mAh g−1 with a current density of 500 mA g−1..
