Abstract
Spherical Li4Ti5O12 and Li4Ti5O12 carbon nanotube (CNT) composites were synthesized using a colloid system. The electrochemical properties of the composites were thoroughly examined to determine their applicability as hybrid capacitor anodes. The electrical conductivity of the spherical Li4Ti5O12-CNT composite was improved over that of the spherical Li4Ti5O12 composite. The synthesized composites were utilized as the anode of a hybrid capacitor, which was assembled with an activated carbon (AC) positive electrode. The CNTs attached on the spherical Li4Ti5O12 particles contributed to a 51% reduction of the equivalent series of resistance of the Li4Ti5O12-CNTs/AC hybrid capacitor compared to the Li4Ti5O12/ AC hybrid capacitor. Moreover, the Li4Ti5O12-CNTs/AC hybrid capacitor showed a larger capacitance than the Li4Ti5O12/ AC hybrid capacitor; specifically, the Li4Ti5O12-CNT/AC hybrid capacitor showed 1.6 times greater capacitance at 40 cycles with a 10 mA cm-2 loading current density.
