<jats:title>Abstract</jats:title><jats:p>Lithium‐ion batteries (LIBs) play a crucial role in using renewable sources. Vanadates have been applied as anode material due to the combined diffusion mechanisms and higher and stable capacities. Despite the interest in vanadates as anode materials, only a few studies have considered Ca<jats:sub>2</jats:sub>V<jats:sub>2</jats:sub>O<jats:sub>7</jats:sub> (CVO) as an active material for LIBs. This work focuses on the use of CVO as a potential alternative anode‐active material for LIBs. Additionally, we investigate the effect of the conductive additive (C65) on the electrochemical properties of the electrodes, utilizing densified electrodes with a porosity of about 40 %. In doing so, this study provides important insights into new materials for LIBs, where the electrodes were manufactured using the commercial slurry methodology, replacing graphite by CVO – which was synthesized via the Pechini route (D50: 8 μm after milling). In summary, the results reveal that the amount of C65 positively affects the electrode‘s capacity. An increase in specific capacity was observed by up to 30 % using 10 wt.% C65. Such electrodes showed 235 mAh/g<jats:sub>AM</jats:sub> at C/10 and, when cycled at 1 C, completed 300 cycles with a retained capacity of 39 %. The results demonstrate that CVO might be a promising anode material for LIB energy storage systems.</jats:p>
