An Ambient Temperature Secondary Aluminum Electrode: Its Cycling Rates and Its Cycling Efficiencies
Electrochemically active aluminum can be cathodically deposited and anodically stripped from acidic mixtures of 1-methyl-3-ethylimidazolium chloride and aluminum chloride at room temperature. The rates of deposition can be high (25 mA/cm sup 2), and the deposited aluminum can be quantitatively cycled in large amounts (>25 C/cm sup 2) at high efficiency (>99%).
