초록
In this paper, we successfully fabricated Al-modified Li4Ti5O12 in one-step, easily, simply, and quickly. The structuralproperties of Li4Ti5O12 by Al modification were favorable to electrochemical activity compared to pristine Li4Ti5O12, and thus,it was confirmed that electrochemical performances such as cell balancing and initial discharge capacitance were effectivelyimproved. The optimized anode/cathode thickness was selected 70 μm/240 μm. Al modified Li4Ti5O12 realized high dischargecapacitance of 61 F/g. Therefore, Al modification can be considered as one of the effective methods for the electrochemicalperformances of Li4Ti5O12 anodes for next-generation hybrid supercapacitors.
