abstract = "Moving toward the commercialization of safe and sustainable energy storage systems, the research on aqueous rechargeable batteries (ARBs) becomes more intensive. Moreover, development of alternative ARBs based on more abundant and sustainable element chemistry (Na, Mg, Ca, and Zn) has received significant attention. Great efforts for their development started to pay off when an aqueous sodium battery (NaTi2(PO4)3//1 M Na2SO4//Na0.44MnO2) appeared on the market alongside organic rechargeable batteries. In this study, a hybrid full- cell aqueous configuration was made from biomass-derived activated carbon (anode), 5 M aqueous solution of Ca(NO3)2 (electrolyte), and layered CaV2O6 (cathode). A high surface area carbon was synthesized by the simultaneous carbonization and activation of vine shoot- derived biochar at 700 °C under Ar atmosphere (ACvs). CaV2O6 composite with the carbon (CaVO/C) was obtained by the sol-gel complexation method. The charge storage behaviour of ACvs and CaVO/C materials was investigated in the aqueous solution of 5 M Ca(NO3)2 and showed promising results. Not only do materials individually exhibit good electrochemical behaviour, full-cell configuration ACvs700//5 M Ca(NO3)2//CaVO/C displayed improved charge storage (89 mAh g-1 at 100 mA g-1) in comparison to mentioned commercial aqueous NaTi2(PO4)3//1 M Na2SO4//Na0.44MnO2 model (≈50 mAh g-1 at ≈100 mA g-1). These results enrich the existing hybrid aqueous battery design and open up a new research era for Ca-ion batteries.",
