The capability of high‐rate cycling and environmental benignity at less expensive defines the ingress of upcoming energy storage system. The urge of such system comes into the picture because today, the state‐of‐the‐art lithium technology is ineffectual to improve its rapid‐charging ability beyond a certain limit, in commercial scale. Here, we introduce reversible electrochemistry of Ca‐ion full cell in conjunction with inexpensive aqueous electrolyte, 1M aq. Ca(ClO 4 ) 2 . In the full cell, carbon cloth, barium hexacyanoferrate (BaHCF) and meso‐carbon microbeads (MCMB) have been explored as the current collector, cathode and anode material, respectively. The full cell provides 40 mAh g ‐1 capacity at 5C rate till 100 cycles. We believe, the investigation of this simple full cell at the early stage of Ca‐ion battery will pave a fast transition in the forthcoming energy storage systems.
