摘要
The shortage of lithium resources is promoting the development of cost-efficient battery candidates, especially aqueous rechargeable batteries (ARBs) with high safety and power density. Copper hexacyanoferrate (CuHCF) nanoparticles with high redox potential and rate capability is employed as the battery cathode for hosting ammonium-ion coupling with low-cost zinc anode. Benefiting from the selective ammonium-ion channel in CuHCF, an aqueous rechargeable zinc ammonium hybrid battery is successfully engineered. It presents high cell voltage (1.8 V), outstanding rate performance, low self-discharge, and satisfactory energy density of 114 Wh kg-1 in consideration of total electrodes' active mass.
