Aqueous metal batteries have the potential to revolutionize the next-generation energy storage infrastructures due to their high energy density, high safety and low cost. However, two major issues of dendrite growth and corrosion reactions in metal anodes have hindered the deployment of this technology. To address these issues, we report an ideal candidate: aqueous cadmium-metal battery (ACB). The metal cadmium (Cd) anode not only shows a high specific capacity (476.5 mAh g-1) but also offers suitable redox potential (-0.4 V versus standard hydrogen electrode). Additionally, we introduce this ACB operating with a low-cost chloride electrolyte composed of CdCl2 and NH4Cl in water. The inclusion of NH4Cl reconstructs the hydrogen bond network of aqueous electrolyte and forms tetrachlorocomplex ([CdCl4]2-), which facilitate ultrafast reaction kinetics in ACBs and endow dendrite-free/corrosion-resistant capabilities in Cd anodes. Consequently, the tailored electrolyte achieves a convincing Coulombic efficiency (99.93%) for Cd plating/stripping behavior at a high anode utilization of 55.5%, making it suitable for practical applications. More importantly, the ACBs demonstrate outstanding compatibility paired with coordination-type, intercalation-type and capacitance-type cathodes, exhibiting excellent high-/low-rate and long-term rechargeable capabilities. On a practical note, the high-load ACB with a low negative-to-positive capacity ratio of 1.91 delivers an impressive lifespan of 800 cycles. In summary, our work suggests a practical aqueous battery capable of supporting robust energy storage infrastructures.
