Aqueous sodium-ion batteries have been proposed as an attractive alternative to large-scale energy storage in terms of safety and economic efficiency. We experimentally confirmed that the potential width of the practical electrochemical window of a highly concentrated aqueous NaClO_4 electrolyte had 2.8 V by using the method of cyclic voltammetry. This positive effect allowed the Na_2MnFe(CN)_6 cathode to operate reversibly at unusually higher potentials in highly concentrated aqueous electrolyte without any side reactions such as undesirable oxidation of water.
